Detailed explanation-1: -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-2: -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.
Detailed explanation-3: -FADH2 produces less ATP then NADH because the electrons for FADH2 are dropped off at the second protein of the electron transport chain. FADH2 produces less ATP then NADH because NADH has more energetic electrons.
Detailed explanation-4: -NADH and FADH2 give their electrons to proteins in the electron transport chain, which ultimately pump hydrogen ions into the intermembrane space. This chemical gradient is used to create ATP using ATP synthase.
