Detailed explanation-1: -So, the correct answer is ‘Acetyl-CoA’.
Detailed explanation-2: -Acetyl CoA is the link between carbohydrate and fat metabolism.
Detailed explanation-3: -Intermediary metabolism refers to the sum of all intracellular chemical processes by which nutritive material is converted into cellular components. It includes anabolism (synthesis of macromolecules) and catabolism (breakdown of macromolecules).
Detailed explanation-4: -Acetyl-CoA, the product of carbohydrate, protein, and lipid catabolism, enters the cycle by forming citrate, and is oxidized to CO2 with the reduction of coenzymes.
Detailed explanation-5: -Summary. The breakdown and synthesis of carbohydrates, proteins, and lipids connect with the pathways of glucose catabolism. The simple sugars are catabolized during glycolysis. The fatty acids from fats connect with glucose catabolism through acetyl CoA.
