Detailed explanation-1: -The Krebs’ cycle oxidizes the carbon atoms of the acetyl group of acetyl coenzyme A resulting from the catabolism of lipids, carbohydrates, and proteins to CO2 and transfers the electrons to NAD+ and FAD that transform to NADH and FADH2.
Detailed explanation-2: -Krebs Cycle Function These carriers are important. They carry the energy used to create a large number of ATP molecules in the final steps of aerobic respiration. The electron carriers produced (NADH and FADH2) cannot provide energy to cellular process directly.
Detailed explanation-3: -The main purpose of Krebs cycle is to generate NADH for the electron transport chain. NADH is important in ETC (electron transport chain) to get oxidized and release electrons and protons and promote chemiosmosis.
Detailed explanation-4: -The citric acid cycle serves as the mitochondrial hub for the final steps in carbon skeleton oxidative catabolism for carbohydrates, amino acids, and fatty acids. Each oxidative step, in turn, reduces a coenzyme such as nicotinamide adenine dinucleotide (NADH) or flavin adenine dinucleotide (FADH2).
