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: -FADH2 produces less ATP then NADH because FADH2 is reduced more. Correct answer: FADH2 produces less ATP then NADH because the electrons for FADH2 are dropped off at the second protein of the electron transport chain.
Detailed explanation-3: -Summary. Electron transport is the final stage of aerobic respiration. In this stage, energy from NADH and FADH2 is transferred to ATP. During electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space.
Detailed explanation-4: -The ETC is a collection of proteins bound to the inner mitochondrial membrane and organic molecules, which electrons pass through in a series of redox reactions, and release energy. The energy released forms a proton gradient, which is used in chemiosmosis to make a large amount of ATP by the protein ATP-synthase.
Detailed explanation-5: -When electrons from NADH move through the transport chain, about 10 H +start superscript, plus, end superscript ions are pumped from the matrix to the intermembrane space, so each NADH yields about 2.5 ATP.
