You have discovered a mutant cell whose glycolytic pathway is shorter because of a new enzyme catalyzing the reaction: NAD+ ? NADH + H+ Glyceraldehyde 3-phosphate + H2O ? 3-phosphoglycerate Please explain why this mutant cell would die under anaerobic conditions but not aerobic conditions.

Step 1
In a normal cell, glycolysis converts glucose to pyruvate, generating 2 ATP and 2 NADH molecules. The NADH molecules are then used in the electron transport chain (ETC) to generate more ATP under aerobic conditions. Under anaerobic conditions, NADH is converted Show more…

'Suppose you discovered a mutant yeast strain whose glycolytic pathway was shorter because of the presence of a new enzyme catalyzing the reaction: Glyceraldehyde 3-phosphate +NAD+ 5 3- phosphoglycerate NADH What effect would shortening the glycolytic pathway in this way have on the cell under anaerobic conditions? What would probably happen to this cell (compare anaerobic to aerobic)? Explain your answer:'
A yeast mutant was discovered with a glycolytic pathway shorter than normal because of the presence of a new enzyme catalyzing the following reaction: Glyceraldehyde-3-Phosphate + H2 + NAD+ --> 3-phosphoglycerate + NADH + H+ Would you expect this yeast to grow under anaerobic conditions? What about aerobic conditions? Fully explain. (4 pts)
