Detailed explanation-1: -High-energy electrons are released from NADH and FADH2, and they move along electron transport chains, like those used in photosynthesis. The electron transport chains are on the inner membrane of the mitochondrion. As the high-energy electrons are transported along the chains, some of their energy is captured.

Detailed explanation-2: -The electron transport chain and ATP synthase are embedded in the inner mitochondrial membrane. NADH and FADH2 made in the citric acid cycle (in the mitochondrial matrix) deposit their electrons into the electron transport chain at complexes I and II, respectively.

Detailed explanation-3: -NADH and FADH2 molecules formed during Glycolysis and Krebs Cycle carry their electrons to the electron transport chain. The electron transport chain creates a proton gradient that ultimately leads to the production of a large amount of ATP.

Detailed explanation-4: -Explanation: Both NADH and FADH2 donate two electrons to the electron transport chain, so theoretically they should make the same amount of ATP.

Detailed explanation-5: -The electrons originally come from glucose. NADH and FADH2 carry electrons to the electron transport chain in cellular respiration. After electron transport in cellular respiration, the electrons are attracted to oxygen molecules (O2) which combine with protons (H+) to make water (H2O) molecules.
