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: -Both NADH and FADH2 are high energy/unstable compounds, like ATP. When electrons are removed from NAPH or FADH2, that is when these molecules are oxidized, this energy is released, and NAD+ and FAD are regenerated.
Detailed explanation-3: -The electron carriers in cellular respiration involve two molecules, called nicotinamide adenine dinucleotide (NAD+) and flavin adenine dinucleotide (FAD).
Detailed explanation-4: -During oxidative phosphorylation, electrons derived from NADH and FADH2 combine with O2, and the energy released from these oxidation/ reduction reactions is used to drive the synthesis of ATP from ADP.
