D)the Krebs cycle.

Question

Quizplus · Accepted Answer

When fatty acids are used to produce ATP, the process begins with the Krebs cycle. This is because fatty acids are broken down into acetyl-CoA, which enters the Krebs cycle to produce ATP. Oxidative phosphorylation and the electron transport chain are both later steps in the ATP production process, after the Krebs cycle. The Calvin cycle is not involved in ATP production, but instead is part of photosynthesis in plants.
