What first happens to the carbon atoms that enter the Krebs cycle as acetyl CoA?

Question

Quizplus · Accepted Answer

The carbon atoms that enter the Krebs cycle as acetyl CoA combine with a 4-carbon sugar (oxaloacetate) to form a 6-carbon sugar (citrate) in the first step of the cycle. This process is known as condensation. The citrate molecule then undergoes a series of chemical reactions that ultimately release carbon dioxide and regenerate the 4-carbon sugar needed to start the cycle again.
