Transport of acetyl CoA from mitochondria:The membrane of the mitochondria is impermeable to acetyl CoA.
By oxidative decarboxylation of pyruvate or oxidation of fatty acids, the mitochondria create acetyl CoA.
When the body has more ATP than it needs, the extra energy is stored as fatty acids.
Acetyl CoA thus starts the TCA cyce
If there is enough energy, acetyl CoA is used in the production of fatty acids.
Acetyl CoA must be moved from the mitochondria to the cytosol because fatty acid production takes place there. Citrate is transported out of mitochondria because it cannot pass the membrane.
The enzyme citrate synthase condenses acetyl CoA and oxaloacetate to produce citrate.
Acetyl CoA is released after citrate is converted back to oxaloacetate in the cytosol.

Explanation:The difference between DNA and gene are summarized below
Difference between Gene and DNA
Gene DNA- Deoxyribonucleic acid
Genes are the DNA stretches which encode for specific proteins. DNA is a biomolecule, which contains genetic information
Regulates the traits of an organism. Regulates gene regulation.
Gene is a specific sequence present on a short stretch of DNA. DNA made up of two long chains of polynucleotides wound together
Genes are made up of either DNA or RNA. DNA is a polymer of nucleotides

Q2.
Oxygen is transported round the body by the blood.
Blood leaving the human lung can carry about 250 milligrams of oxygen per litre.
However, only 7 milligrams of oxygen will dissolve in one litre of water at body
temperature.
(a) Suggest an explanation for the difference.
The blood compared to the amount that can dissolve in water at body temperature can be explained by the presence of specialized oxygen-carrying molecules in the blood called hemoglobin.
What is the heamoglobin?Red blood cells' hemoglobin molecules serve as the primary carrier of oxygen in the bloodstream. Due to hemoglobin's strong affinity for oxygen, it can attach to oxygen molecules in the lungs and release them when necessary for tissues.
Compared to the restricted solubility of oxygen in water, this mechanism considerably increases the amount of oxygen that can be delivered in the blood.

the sodium-potassium pump is a trans-membrane protein. group startstrue or falsetrue, unselectedfalse, unselected
It is true that the sodium-potassium pump is a trans-membrane protein.
What is the sodium-potassium pump?The sodium-potassium pump is an essential protein found in the cell membranes of all animal cells. This protein helps maintain the resting potential of cells and is particularly essential in neurons and muscle cells. In the nerve cells of animals, the sodium-potassium pump is crucial for transmitting action potentials, which is essential for nerve transmission and muscle function.
The sodium-potassium pump is responsible for maintaining the normal cell functions of a cell by transferring three sodium ions (Na+) from inside the cell to the outside, while at the same time allowing two potassium ions (K+) to enter the cell. As a result, the concentration of potassium ions inside the cell is higher than the concentration of sodium ions outside the cell.
To transport these ions across the membrane, the pump utilizes a trans-membrane protein that spans the cell membrane. As a result, the sodium-potassium pump is classified as a transmembrane protein.

did not eat breakfast this morning before she headed out to class. As a result the hormone ________ will be released by her _________ in an effort to raise blood glucose levels.
The hormone cortisol will be released by her liver in an effort to raise blood glucose levels.
Why is blood sugar high before breakfast in the morning?Hormones like cortisol and growth hormone indicates the liver to increase the production of glucose in the early morning, which gives us energy to wake up. In order to maintain healthy blood glucose levels, this causes the pancreatic beta cells to release insulin.
Blood sugar levels will already be lower if we don't eat, and any medication we take could further lower them, which could result in hypoglycemia. We can become unsteady, faint, or even fall into a coma as a result of hypoglycemia. We run the risk of developing too-high blood sugar levels when we eat to "break" your fast.

When sea levels rise as rapidly as they have been, even a small increase can have devastating effects on coastal habitats farther inland. It can cause destructive erosion, wetland flooding, aquifer and agricultural soil contamination with salt, and lost habitat for fish, birds, and plants. What happens to biodiversity in coastal communities as the sea level rises?
Biodiversity decreases because plants and animals adapted for fresh water will not survive and reproduce in a different environment.
What is sea rise?The term sea rise has to do with a situation in which there is a sudden increase in the sea level. This could lead to a sudden overflow of water into rivers lakes and ponds.
We know that sea water is salty, there is excess salt concentration in a sea water while fresh water does not contain salt at all. In these cases whereby there is an overflow of seawater, the water carries salt along with it. This implies that land and fresh water could become contaminated with this salt and that would have catastrophic effects on these ecosystems.
Since fresh water organisms can not tolerate a sudden increase in the concentration of salt in the ecosystem, biodiversity decreases because plants and animals adapted for fresh water will not survive and reproduce in a different environment.

Explanation:
osmolarity-detecting cells located in the nuclei of the (click to select) are stimulated by an increasing blood solute concentration.
An increasing blood solute content stimulates osmolarity-detecting cells in the hypothalamic nuclei, notably the supraoptic and paraventricular nuclei.
The control of antidiuretic hormone (ADH), also known as vasopressin, is the responsibility of these cells.Osmoreceptor cells in the hypothalamus notice changes when blood osmolarity rises, a sign of higher solute concentration. The posterior pituitary gland releases ADH as a result of the stimulation of the osmoreceptor cells, which then send signals to the supraoptic and paraventricular nuclei.Purification of urine and a reduction in water loss from the body are both aided by ADH's action on the kidneys to encourage water reabsorption. The release of ADH by the osmoreceptor cells in response to an increase in blood solute concentration contributes to maintaining correct osmolarity and fluid balance.

1. Why are the chromosomes paired up?
Answer: Chromosome pairing refers to the lengthwise alignment of homologous chromosomes at the prophase stage of meiosis. ... For these organisms to produce cells with a single set of chromosomes, the sets have to be separated such that the daughter cells have one copy of each chromosome. The 22 pairs of homologous chromosomes contain the same genes but code for different traits in their allelic forms since one was inherited from the mother and one from the father. So humans have two homologous chromosome sets in each cell, meaning humans are diploid organisms.

A. a buffering solution
B. extra substrate
C. an acid
D. a base
Answer:
maybe the answer is C..sorry if i wrong
If an experiment was being conducted using an enzyme that was very sensitive to changes in pH, a buffering solution must be added in order to prevent the enzyme from denaturing. Thus, the correct option for this question is A.
What is the denaturation of an enzyme?The denaturation of an enzyme may be defined as a process through which a molecular structure of an enzyme gets deviate from its original state due to exposure to high temperature, pH sensitivity, etc.
The function of a buffering solution is to stabilize the pH of the given solution. It helps the other component of the solution to resist in response to pH change. A Buffer solution is capable to neutralize the effect of the small amount of acid or base.
Therefore, a buffering solution must be added in order to prevent the enzyme from denaturation. Thus, the correct option for this question is A.
