Detailed explanation-1: -Answer and Explanation: During cellular respiration, NADH delivers its electron “cargo” to the first electron transport chain protein complex and is d. reduced to form NAD+ N A D + . NADH is formed in glycolysis, beta-oxidation of fats and in the citric acid cycle.
Detailed explanation-2: -NADH: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.
Detailed explanation-3: -Electrons from NADH enter the electron transport chain in complex I, which consists of nearly 40 polypeptide chains (Figure 10.8). These electrons are initially transferred from NADH to flavin mononucleotide and then, through an iron-sulfur carrier, to coenzyme Q-an energy-yielding process with
