Question

Quizplus · Accepted Answer

The common molecule produced from all foods at the second stage of catabolism is acetyl-CoA. This is because during the second stage of catabolism (Krebs cycle), the breakdown products from glucose, fats, and proteins are converted into acetyl-CoA, which is then used in the electron transport chain to produce ATP. ADP, glucose, citric acid, and carbon dioxide are also involved in cellular respiration but are not specifically produced during the second stage of catabolism.
