Question

Glycolysis Shortcut Suppose you discovered a mutant yeast whose glycolytic pathway was shorter because of the presence of a new enzyme catalyzing the reactionGlyceraldehyde 3-phosphate□H2O3-phosphoglycerateNAD□NADH□H□Would shortening the glycolytic pathway in this way benefit the cell? Explain.

Answer 1

Answer:

No.

Explanation:

As you may already know, glycolysis is an anaerobic metabolic pathway, that is, without the presence of oxygen, which is able to break down glycolysis into smaller molecules that are capable of providing energy (ATP) to living beings after a series coordinated and indispensable reactions.

In the question above, we can see that a cinetist discovered a mutant yeast that was able to perform glycolysis more quickly due to the presence of a certain enzyme. If we analyze the reaction that this enzyme is capable of generating, we can conclude that the shortening of glycolysis is not beneficial to the cell. This is because the amount of ATP produced anaerobically, by glycolysis, would be non-existent. Aerobic ATP production would also be affected, but on a small scale.
