What is the net yield of ATP/GTP through substrate-level phosphorylation for every Acetyl CoA that enters the TCA cycle?
Show answer and explanation
Correct answer: 1
Each turn of the TCA cycle (driven by one Acetyl CoA) produces exactly one molecule of ATP (or GTP) directly through substrate-level phosphorylation during the succinyl-CoA to succinate conversion.
