Question
A molecule of acetyl-CoA enters the citric acid cycle. How many molecules of ATP (if any) are used during this process?
Solution
No molecules of ATP are used during the citric acid cycle. Instead, the cycle produces ATP. Specifically, for each acetyl-CoA that enters the cycle, one molecule of ATP (or an equivalent) is produced. The citric acid cycle is part of cellular respiration, which overall produces ATP, it does not consume it.
