Answer: Option C) pyruvate kinase and phosphoglycerate kinase
Explanation:
The last five reactions of the glycolysis refers to the Pay-Off phase. Here, energy is liberated in the form of ATP as:
- phosphoglycerate kinase catalyzes the conversion of 1,3-Diphosphoglycerate to 3-Phosphoglycerate
- Pyruvate kinase catalyzes the conversion of Phosphoenolpyruvate to pyruvate
Thus, pyruvate kinase and phosphoglycerate kinase catalyzes ATP-yeilding reactions of the Pay-Off phase
