Two molecules of what compound are produced by glycolysis? Does this molecule enter the citric acid cycle?
The citric acid cycle can be divided into two stages. In one stage, carbon atoms are added and removed, and in the second stage, oxaloacetate is regenerated. Which steps of the citric acid cycle correspond to each stage?
Two carbon atoms are fed into the citric acid cycle as acetyl-CoA. In what form are two carbon atoms removed from the cycle?
