Quizplus · Accepted Answer

The majority of carbon dioxide produced during aerobic respiration is a byproduct of the Krebs cycle (also known as the citric acid cycle or TCA cycle). During this cycle, acetyl CoA (derived from the breakdown of glucose, fats, or proteins) is oxidized to carbon dioxide and water, generating ATP and reducing power in the form of NADH and FADH2. The carbon dioxide is then released as a waste product. While carbon dioxide is also formed in the electron transport chain, it is a smaller fraction of the total amount produced compared to the Krebs cycle.
