Detailed explanation-1: -The reactants of the electron transport chain are NADH, FADH2, protons, ADP, and oxygen. NADH and FADH2 are electron carriers produced during glycolysis and the Citric Acid Cycle that donate electrons to the protein complexes in the inner membrane of the mitochondria.
Detailed explanation-2: -At the inner mitochondrial membrane, electrons from NADH and FADH2 pass through the electron transport chain to oxygen, which provides the energy driving the process as it is reduced to water. The electron transport chain comprises an enzymatic series of electron donors and acceptors.
Detailed explanation-3: -The reactants are pyruvate, NADH, and a proton. The products are lactate and NAD+. The process of fermentation results in the reduction of pyruvate to form lactic acid and the oxidation of NADH to form NAD+. Electrons from NADH and a proton are used to reduce pyruvate into lactate.
Detailed explanation-4: -NADH and FADH2 carry high-energy electrons to the electron transport chain in cellular respiration. NADPH carries high-energy electrons to the electron transport chain in photosynthesis.
Detailed explanation-5: -The Electron Transport Chain Stage three of cellular respiration is the use of NADH and FADH2 to generate ATP.
