What is the final product of the Krebs cycle?

Explanation

The Krebs cycle, also known as the citric acid cycle, begins when acetyl-CoA combines with oxaloacetate to form citrate. Through a series of reactions, citrate is converted back to oxaloacetate. At the end of the cycle, oxaloacetate is regenerated, making it the final product. This regeneration is crucial as it allows the cycle to continue by accepting another acetyl-CoA. Malate, succinate, and fumarate are intermediates in the cycle and are not the final product. Malate is further oxidized to oxaloacetate, succinate is converted to fumarate, and fumarate is hydrated to malate. Thus, only oxaloacetate completes the cycle, ready to initiate the next round.
