If acetyl-CoA, uniformly labeled with 14C in the acetyl group, is condensed with unlabeled oxaloacetate and the product is oxidized via the Krebs cycle, how much of the original radioactivity will be found in the oxaloacetate formed after one turn of the cycle?

Question

Quizplus · Accepted Answer
