Explanation:
Detailed explanation-1: -Kreb’s cycle is the second phase of aerobic respiration during which acetyl CoA condenses with OAA to form citrate which undergoes oxidative decarboxylation forming 3 molecules of NADH2 and one molecule FADH2.
Detailed explanation-2: -In each round of -oxidation, 1 molecule of acetyl-CoA, 1 molecule of NADH, and 1 molecule of FADH2 are produced.
Detailed explanation-3: -Products of the Citric Acid Cycle Each turn of the cycle forms three NADH molecules and one FADH2 molecule. These carriers will connect with the last portion of aerobic respiration to produce ATP molecules.
