The Pay-Off phase. Which two reactions pay-off ATP?a. Enolase and triose phosphate isomerase glyceraldehyde b. 3-phosphate dehydrogenase and phosphoglycerate c. kinase pyruvate kinase and phosphoglycerate d. kinase phosphoglycerate mutase and pyruvate kinase

Respuesta :

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
