B. Phosphorylase is a better enzyme than hexokinase
C. Phosphorylase produces a glucose phosphate without spending an ATP to do it
D. All of these
Answers
Answer:
A
Explanation:
The answer is a Because Phosphorolysis reactions cleave bonds with phosphate instead of water (: just trust me
Glycolysis that starts with glycogen instead of glucose can be considered to have a higher energy yield because phosphorolysis reactions cleave bonds with phosphate instead of water. The correct option is A.
What is glycolysis?Through a sequence of processes known as glycolysis, glucose is divided into two pyruvate molecules, each of which has three carbons.
The metabolic process that changes glucose into pyruvate is known as glycolysis.
The high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process. A series of ten enzyme-catalyzed processes make up glycolysis.
In contrast to phosphorolysis reactions, which cleave bonds with phosphate rather than water, glycolysis can be thought of as having a larger energy yield because it begins with glycogen rather than glucose.
Not producing adenosine 5′-triphosphate is not the primary goal of glycolysis; rather, it is to produce pyruvate for the trichloroacetic acid (TCA) cycle.
By boosting the ratio of NADH to NAD+, the glycolytic synthesis of pyruvate lowers the cytosol.
Thus, the correct option is A.

In the following scenario, identify which stretching technique is being emphasized. Choose from ballistic, static, PNF, or dynamic stretching techniques. A ballet dancer stands facing a barre on one leg and forcefully lifts the nonstanding leg back over the head repeatedly. What type of stretch is this?
Answers
The stretching technique being emphasized in this scenario is ballistic stretching.
Ballistic stretching involves using momentum and force to move the body part beyond its normal range of motion. In this scenario, the ballet dancer is using force to lift the nonstanding leg back over the head repeatedly.
Ballistic stretching is often used in activities that require explosive movements, such as dancing or sprinting. However, it is also considered a high-risk stretching technique as it may lead to injury if not performed properly.
It is generally not recommended for beginners or those with limited flexibility. Instead, static and dynamic stretching are more commonly recommended for improving flexibility and reducing the risk of injury.

Organisms can be made up of many cells, which could be arranged into tissues, which can make up organs, organs can be part of an organ system. These are parts of the body.
Organisms can be unicellular (e.g., bacteria and protists) or multicellular (e.g., fungi, plants and animals).In multicellular organisms, cells are organized into tissues (e.g., connective tissue) that play specialized functions.In turn, two or more tissues can be organized to form organs (e.g., liver, kidney) that perform specific functions for the body. Finally, organs are arranged into systems that work together to carry out a particular function for the body. For example, the urinary system is responsible for cleaning and filtering the blood of waste products.The organ systems include the cardiovascular system, respiratory system, digestive system, nervous system, endocrine system, integumentary system, skeletal system, muscular system, lymphatic system, urinary system, and reproductive system.In conclusion, the correct levels of organization (from smallest to largest) are cells >> tissues >> organs >> organ system.

Suppose 14C-labeled CO2 is used to form malonyl-CoA from acetyl-CoA. If this labeled malonyl-CoA is used for palmitate synthesis, which carbon atom(s) in the fatty acid would be radiolabeled? a. All even numbered carbons. b. The methyl terminal carbon. c. All odd numbered carbons. d. Only the alpha and beta-carbons. e. None of the carbons. Submit Answer Tries 0/99
Answers
If 14C-labeled CO2 is used to form malonyl-CoA from acetyl-CoA, the carbon atoms that would be radiolabeled in the resulting palmitate fatty acid are all even numbered carbons.
Palmitate synthesis involves a series of condensation reactions where malonyl-CoA units are added to a growing fatty acid chain. In each condensation step, the malonyl group is incorporated into the fatty acid chain, while the CoA moiety is released.
The acetyl-CoA that serves as a precursor for palmitate synthesis comes from the breakdown of glucose or other energy sources. When 14C-labeled CO2 is used in the conversion of acetyl-CoA to malonyl-CoA, the radiolabel is incorporated into the carbon skeleton of the malonyl group.
Since malonyl-CoA is used iteratively to extend the fatty acid chain, the radiolabeled carbon from the malonyl group will be present in each subsequent addition of a malonyl group. As a result, all even-numbered carbons in the resulting palmitate fatty acid would be radiolabeled. Therefore, the correct answer is option a.

Answers
There will be 104 light sunfish expected for the population to be in Hardy-Weinberg equilibrium.
The Hardy-Weinberg equation enables us to foretell which of them they are. It is feasible to determine p since p = 1 - q and q is known. When p and q are known, it is easy to enter these numbers into the Hardy-Weinberg equation (\(p^{2}\) + 2pq + \(q^{2}\) = 1). This then gives the population's projected frequencies for each of the three genotypes for the chosen characteristic.
In this equation, \(p^{2}\) is the population's anticipated frequency of homozygous dominant individuals (AA), 2pq is the population's predicted frequency of heterozygotes (Aa), and \(q^{2}\) is the population's predicted frequency of homozygous recessive individuals (AA).
Because they lack the dominant characteristic, homozygous recessive individuals, or \(q^{2}\) in the equation, are typically the only ones whose frequency can be determined from observations of phenotypes. Either homozygous dominant (\(p^{2}\)) or heterozygous individuals might exhibit the characteristic in their phenotypic (2pq).

Does crossing over decrease genetic variation?
Answers
Chromosome crossover increases genetic variability by giving offspring chromosomes that differ from those of their parents.
The degree of genetic variation in a population is significant because natural selection depends on different alleles to change their frequencies for the better or worse.
Crossover is a process that results in fresh allele combinations in the gametes (egg or sperm) produced, assuring genetic diversity in any offspring produced.
Meiosis, also known as crossing over or recombination, is a process in which nonsister chromatids swap chromosomal regions. Cross-pollination creates new gene combinations in the gametes that are not present in either parent, increasing genetic diversity.
A species' genetic diversity is largely a result of meiosis. Two processes—independent assortment and crossing over—are the main means by which it achieves this (recombination).
