Question

fill in the blank question

atp is produced during reaction number blank and reaction number blank of glycolysis.

Explanation:

Identify ATP-producing steps in glycolysis

In the standard 10-step metabolic pathway of glycolysis, ATP is generated via substrate-level phosphorylation in the payoff phase:

1. Reaction 7: Phosphoglycerate kinase transfers a phosphate group from 1,3-bisphosphoglycerate to ADP, forming ATP and 3-phosphoglycerate.
2. Reaction 10: Pyruvate kinase transfers a phosphate group from phosphoenolpyruvate (PEP) to ADP, forming ATP and pyruvate.

Determine the reaction numbers

The reaction numbers where ATP is produced are 7 and 10.

Answer:

ATP is produced during reaction number <blank>7</blank> and reaction number <blank>10</blank> of glycolysis.
