At which two steps is ATP generated in glycolysis?
Correct answer: B. 1,3-BPG → 3-PG and PEP → Pyruvate
- A. G3P → 1,3-BPG and 1,3-BPG → 3-PG
- B. 1,3-BPG → 3-PG and PEP → Pyruvate
- C. G3P → 1,3-BPG and PEP → Pyruvate
- D. 2-PG → PEP and PEP → Pyruvate
Explanation
ATP is produced at two substrate-level phosphorylation steps:1) 1,3-BPG → 3-PG (via phosphoglycerate kinase)2) PEP → Pyruvate (via pyruvate kinase).
