FAQs
Question: What is the main function of the TCA Cycle? Answer: The main function of the TCA Cycle is to generate energy through the oxidation of acetyl-CoA, producing ATP, NADH, and FADH2.
Question: How does the TCA Cycle relate to aerobic respiration? Answer: The TCA Cycle is a key component of aerobic respiration, as it occurs in the mitochondria and contributes to the production of energy carriers that are used in the electron transport chain.
