Detailed explanation-1: -NADH: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain. FADH2: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.

Detailed explanation-2: -NADH and FADH2 are electron carriers during the process of cellular respiration. They transport high energy electrons which were in the carbon-hydrogen covalent bonds of glucose to the electron transport chain where a series of redox reactions move those electrons to the terminal electron acceptor of oxygen.

Detailed explanation-3: -NADH and FADH2 are high energy molecules and they can be used as reducing agents by the cell.

Detailed explanation-4: -The Electron transport chain is the third stage of cellular respiration and is illustrated in Figure 4.10. 8. During this stage, high-energy electrons are released from NADH and FADH2, and they move along electron-transport chains on the inner membrane of the mitochondrion.

Detailed explanation-5: -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.
