In the Krebs cycle, substrate-level phosphorylation occurs during a single specific step. Identify the transformation where this ATP (or GTP) production happens.
Q1. In the Krebs cycle, substrate-level phosphorylation occurs during a single specific step. Identify the transformation where this ATP (or GTP) production happens.
Answer: Succinyl-CoA to Succinate
Explanation: ATP is produced directly during the conversion of Succinyl-CoA to Succinate; other steps produce NADH or FADH2 via redox.
