Detailed explanation-1: -Final answer: Acetyl CoA is the biomolecule that is common to respiration mediated breakdown of fats, carbohydrates, and proteins.

Detailed explanation-2: -Aerobic metabolism is the most efficient way of producing ATP by producing 18 times more ATP for each molecule of glucose than anaerobic metabolism. Although the primary source of ATP in aerobic metabolism is carbohydrates, fatty acids and protein can also be used as fuel to generate ATP.

Detailed explanation-3: -Cell Respiration: Cell respiration is the process of producing energy through the oxidation of food molecules such as carbohydrates, fats, and proteins into carbon dioxide and water.
