What makes transmembrane proteins unique to non transmembrane proteins. i.e. what makes them become embedded in the er membrane while others don't?
Answers
Many transmembrane proteins feature as gateways to allow the transport of precise materials throughout the membrane. They frequently undergo large conformational adjustments to transport a substance thru the membrane. they may be commonly exceedingly hydrophobic and combine and precipitate in water.
Transmembrane and peripheral proteins are forms of membrane proteins present inside the cell membrane. Transmembrane proteins form channels and pores to move molecules across the membranes. in the meantime, the peripheral proteins on the extracellular surface are responsible for cellular-cell signaling and interactions.
Transmembrane proteins that amplify via the bilayer w/ part of their mass on either facet are amphipathic. -hydrophobic components (facet chains) interact with hydrophobic tails of lipids. -hydrophilic components are uncovered on both facets of the membrane.

5. fewer amounts of the hormone
6. parathyroid hormone-like hormone (PTHLH)
7. the thyroid and parathyroid glands
8. Steroid hormones are produced from cholesterol, while nonsteroid hormones are produced from amino acids.
Explanation:
Hormones are signaling molecules secreted by the body to control cellular activities The endocrine glands are glands that don't have ducts to carry their secreted products (hormones) to the surface. Endocrine glands include the hypothalamus, ovaries, testes, pancreas, adrenal glands, parathyroid glands, pituitary gland, pineal gland, thymus and thyroid glands. The pituitary gland is an endocrine gland that secretes many hormones into the bloodstream, which are capable of controlling the functioning of other organs and glands. During the puberty stage, this gland secretes LH and FSH gonadotropin hormones that affect male and female gonads in order to activate the production of sex hormones. The adrenal glands secrete cortisol, which is known as the stress hormone. These glands also produce adrenaline which regulates visceral functions such as, for example, respiration. The parathyroid hormone-like hormone (PTHLH) is generated by epithelial cells and plays important roles in fetal and adult tissues, (i.e., cell proliferation, differentiation and morphogenesis). The thyroid gland regulates body temperature, while parathyroid glands control the calcium level in the blood by secreting the parathyroid hormone (PTH). Steroid hormones are lipidic hormones known to bind steroid receptors and they can easily cross the cell membrane, while non-steroid hormones cannot diffuse across the cell membranes and they are secreted by the endocrine system.
Advantages of seed development
Answers
Answer:
The advantages of seed development include increased crop yields, improved disease resistance, and enhanced nutritional content.
Seed development in plants provides several advantages, including protection and dispersal of offspring, dormancy for survival in unfavorable conditions, and a nutrient-rich food source for germination and early growth.
Seed development in plants offers various advantages that contribute to their reproductive success and survival.
One key advantage is the protection and dispersal of offspring. Seeds are enclosed within a protective seed coat, which shields the embryo from external threats such as desiccation, mechanical damage, and predation. Additionally, seeds have adaptations for dispersal, allowing them to spread over a wider range and colonize new habitats.Another advantage is dormancy. Seeds can enter a state of dormancy, remaining inactive until conditions become favorable for germination and growth.This allows plants to survive through periods of unfavorable environmental conditions such as drought, extreme temperatures, or lack of sunlight. Dormancy also enables seeds to delay germination until suitable resources and conditions for growth are available.
Furthermore, seeds serve as a nutrient-rich food source for the developing embryo. They contain stored reserves of carbohydrates, proteins, and lipids that provide energy and nutrients for germination and early growth when the seedling is not yet photosynthetically active.In summary, seed development in plants provides advantages such as protection and dispersal of offspring, dormancy for survival during unfavorable conditions, and a nutrient supply for early growth and development. These traits contribute to the reproductive success and resilience of plants in diverse environments.

Cancer is one of the leading causes of death in our society. Cancer is a disease in which a
cell in the body loses its sensitivity to factors which regulate cell growth and division. The
cell begins to multiply without restriction, creating a growing mass called a tumor, which
interferes with the structure and functioning of the organ in which it is located.
Frequently, cancer cells become metastatic, meaning that they travel, settling in a number
of places and giving rise to secondary tumors. Much of medical research is devoted to
finding ways of preventing, controlling, and curing cancer.
Because of the metastatic trait of cancer cells, how can we judge a cancer treatment to be
effective?

Which of the following mutations would most likely keep the transitions of T state to R state in hemoglobin unchanged, or similar to the transitions that occur in the native molecule? The three-letter codes for amino acids are used, and the numbers following the amino acids designate the amino acid position in the protein. By convention, the original, native amino acid is listed first, followed by the mutational change. Choose one: O A. Asp94lle94 O B. Tyr42–Phe42 O C. Asp94-Glu94 O D. Tyr42-Gly42
Answers
The Tyr42-Phe42 substitution is the most conservative substitution and is therefore the most likely to preserve the T-to-R transition in hemoglobin.
Hemoglobin is a complex protein that undergoes a conformational change from a tense (T) state to a relaxed (R) state upon binding to oxygen. The T state has a low affinity for oxygen, while the R state has a high affinity for oxygen. Therefore, mutations that alter the T-to-R transition in hemoglobin can have significant effects on its oxygen-binding properties and its ability to transport oxygen throughout the body.
Of the mutations listed, the one that is most likely to keep the T-to-R transition unchanged or similar to the native molecule is the Tyr42-Phe42 substitution. This is because tyrosine and phenylalanine are both aromatic amino acids that have similar chemical properties, including hydrophobicity and π-electron density. Therefore, this substitution is not likely to disrupt the interactions between the hemoglobin subunits that are responsible for the T-to-R transition.

How does exhaling remove waste from the body? Explain the systems that make this happen, using complete sentences.
Answers
Exhaling removes waste from the body by expelling carbon dioxide through the respiratory system.
Exhaling plays a crucial role in removing waste from the body, particularly in the form of carbon dioxide (CO2), a byproduct of cellular respiration. The respiratory system, composed of the lungs and airways, is primarily responsible for this process.During inhalation, air containing oxygen is drawn into the lungs through the nose or mouth. Oxygen then diffuses across the lung tissue into the bloodstream, where it binds to hemoglobin and is transported to cells throughout the body. In the cells, oxygen is utilized in metabolic processes, generating energy and producing CO2 as a waste product.When we exhale, the diaphragm and intercostal muscles relax, causing the volume of the chest cavity to decrease. This action increases the pressure within the lungs, and air rich in CO2 is expelled from the body through the airways. The CO2 is removed from the bloodstream and eliminated from the body, reducing the waste buildup.Overall, the respiratory system's main function is to facilitate the exchange of gases, allowing oxygen to enter the body and carbon dioxide to be eliminated. Exhalation plays a vital role in removing waste by expelling CO2 and maintaining a balanced gas composition within the body.For more questions on respiratory

Proteins in the plasma membrane are often the target of medicines. In paragraph format (at least four sentences), explain why this is the case.
Answers
Argeting proteins in the plasma membrane offers a promising approach for developing new medicines that can be used to treat a wide range of diseases and conditions.
What is Plasma Membrane?
The plasma membrane, also known as the cell membrane, is a thin layer of lipid and protein molecules that surrounds and encloses the cell. It serves as a barrier between the interior of the cell and its external environment, regulating the movement of substances in and out of the cell. The plasma membrane is composed of a phospholipid bilayer, which consists of two layers of phospholipid molecules with their hydrophilic (water-loving) heads facing outward and their hydrophobic (water-fearing) tails facing inward. Embedded within the phospholipid bilayer are various proteins, which perform a variety of functions such as transporting molecules across the membrane, receiving signals from other cells, and providing structural support.
Proteins in the plasma membrane are crucial for many cellular processes, including cell signaling, transport, and recognition. As such, they are often the targets of drugs and medications because they can be used to modulate or disrupt these processes. For example, many cancer drugs target proteins in the plasma membrane that are involved in cell signaling pathways, as this can help to slow down or stop the growth of cancer cells.
Additionally, drugs that target membrane transporters or channels can be used to regulate the flow of ions or molecules in and out of cells, which can be useful for treating diseases such as hypertension or cystic fibrosis.

Carlton and Vanessa are lab partners in their biology class. One of their labs was to run the smell test experiment on each other.
When performing the smell test, Vanessa was quite good at noticing a difference between the various intensities of vanilla and also
the various intensities of evergreen. Although Carlton could distinguish what the vanilla and evergreen smells were, he couldn't tell
there was a difference in the intensities in the vanilla or the evergreen. Based on the information presented in this scenario, which
of the following is true?
Vanessa has a more sensitive difference threshold than Carlton.
Carlton has an impaired absolute threshold.
Vanessa has a better absolute threshold than Carlton.
Carlton has the superior performance with respect to the difference threshold.
Vanessa has an impaired absolute threshold.
Answers
Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.
Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.
Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.
Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.
The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.
Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.
This shows that Carlton has an impaired absolute threshold.
He could not detect the smallest quantity of a stimulus to differentiate between the smells.
Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.
This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.
Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

The primary role of phospholipids is to form cell membranes. Phospholipids are a type of lipid molecule that consists of a hydrophilic head and a hydrophobic tail. In the cell membrane, the hydrophilic head faces the aqueous environment, while the hydrophobic tail is oriented towards the interior of the membrane. This creates a selectively permeable barrier that allows certain molecules to pass through the membrane while preventing others from doing so. Phospholipids play a crucial role in maintaining the structure and function of cell membranes.
