You are studying a biochemical pathway and isolate mutants I, II, and III. Mutant I can grow if you supplement the medium with Z

. Mutant II can grow if you supplement the medium with X, Y, or Z. Mutant III can grow if you supplement the medium with X and Z, but not if you supplement the medium with Y. What is the order of X, Y, and Z in this biochemical pathway?
a) X, Y, Z
b )Y, Z, X
c) Z, X, Y
d) Y, X, Z
e) X, Z, Y

Answer:

d) Y, X, Z

Explanation:

Mutant I only grows when the medium is supplemented with Z. So Z is the final product of biochemical pathway since supplying other intermediates do not lead to any growth.

Mutant III can grow if medium is supplemented with X and Z but not with Y. This means that Y is the first intermediate in this pathway since mutant III is not able to convert it into X and hence needs to be supplemented with next intermediate product X for growth.

Hence the correct order of X, Y and Z in this biochemical pathway is Y, X, Z.

Marrrta [24]

Answer: 1. Glycogen

2. Glycogenesis

3. Fatty acids

4. Catabolic reactions

5. Pyruvate

6. Fermentation

Explanation:

1. Glucose and glycogen metabolism are the primary source of ATP through glycolysis, which provides Acetyl co A needed for further generation of ATP in citric acid cycle.

2. Glycogenesis is an anabolic reaction which involves the building of glycogen chain from glucose units. Anabolic reactions involve the building of macromolecules from smaller building blocks.

3. Gluconeogenesis involves the synthesis of glucose from non glucose precursors like amino acids from protein and fatty acids from lipids.

4. Catabolic reactions involve the breakdown of macromolecules into simpler and smaller building blocks.

5. Pyruvate is the last product in glycolysis where phosphoenol pyruvate is converted to Pyruvate by the enzyme, pyruvate kinase.

6. Private has two fates; aerobic respiration and anaerobic fermentation. In anaerobic fermentation, pyruvate is either reduced to lactate through lactic acid fermentation or converted to ethanol and water in low oxygen conditions.

san4es73 [151]

Proximate; mechanistic best describes the class of questions that Insel and Young were addressing when they studied the effect of anti-diuretic hormone on monogamous voles.

Explanation:

Genetic researchers, Insel and Young, conducted various studies to analyze the neurobiological aspects of pair bonding on monogamous voles. This was done by studying the changes observed due to the action of the antidiuretic hormone, vasopressin, when their receptors were increased. The transgenic voles exhibited differential gene expressions which explained the proximate and mechanistic mating behavior.

The role of the antidiuretic hormone explained the neurochemical mechanisms of the voles mating behaviors like bonding, attachment etc. Rather than increasing the amount of hormone, just by increasing the receptors of the hormone, male voles showed an increased social reproductive behavior.
