Which of the following molecules directly enters the citric acid cycle?

Question

Quizplus · Accepted Answer

Acetyl CoA directly enters the citric acid cycle by combining with oxaloacetic acid to form citric acid. Adenosine diphosphate (ADP) is not a molecule that enters the citric acid cycle, but rather a molecule that is produced during the process of oxidative phosphorylation. Citric acid and oxaloacetic acid are both intermediates of the citric acid cycle and are not molecules that directly enter the cycle.
