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:

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.

This shortening of the glycolytic pathway wouldn't benefit the cells (anaerobic cells) because ATP isn't being produced and energy gain will be equal to 0.

What are cellular respiration and glycolysis?

Cellular respiration refers to a series of chemical reactions by which a cell can produce energy in the form of ATP by using oxygen and the chemical energy from foods.

  • Glycolysis represents the first step during the process of cellular respiration, and the only single step during anaerobic respiration.

  • Moreover, phosphoglycerate kinase and pyruvate kinase are key enzymes in anaerobic reactions to produce ATP from Glyceraldehyde 3-phosphate (G3P).

  • Mutations in these enzymes won't be beneficial for anaerobic cells because it will lead to disruption in ATP synthesis.

In conclusion, this shortening of the glycolytic pathway wouldn't benefit the cells (anaerobic cells) because ATP isn't being produced and energy gain will be equal to 0.
