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: -Answer and Explanation: Electron Transport Chain (ETC) is a series of reactions that takes place in mitochondria. It uses NADH and FADH2 as a reactant to produce energy in the form of ATP. It also produces water as a product.
Detailed explanation-3: -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-4: -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-5: -The reactants are glyceraldehyde-3-phosphate (a carbon compound), Pi (inorganic phosphate), and NAD+. These three reactants enter into a chemical reaction to produce two products, NADH and 1, 3-bisphosphoglycerate.
