Detailed explanation-1: -To summarize, for complete oxidation of a glucose molecule, Krebs cycle yields 4 CO2, 6NADH, 2 FADH2 and 2 ATPs. Each molecule of NADH can form 2-3 ATPs and each FADH2 gives 2 ATPs on oxidation in the electron transport chain.
Detailed explanation-2: -FADH2 and NADH are created from FAD and NAD+ through reduction-oxidation reactions in the Krebs cycle during respiration as seen below: This cycle gives off small amounts of energy in the form of adenosine triphosphate, or ATP, and produces these compounds, FADH2 and NADH. The Krebs cycle is like a wheel.
Detailed explanation-3: -Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.
Detailed explanation-4: -The citric acid cycle takes place in the matrix, or inner fluid of the mitochondrion. The citric acid cycle involves eight chemical reactions that produce carbon dioxide, ATP, NADH and FADH2. The NADH and FADH2 are electron carriers that can be used by the electron transport chain (ETC).
