Kreb's cycle. Site of Reaction : Mitochondrial matrix in Eukaryotes Electron Transport Chain. The malate—aspartate shuttle is sensitive to the NADH/NAD+ ratios in the cytosol and mitochondria, and cannot operate if the mitochondrial NADH/NAD+ ratio is higher than that in the cytosol. They are used in the production of ATP, the 'energy currency' of the cell. The electrons ultimately reduce O2 to water in the final step of electron transport. The difference in energy between the products and the reactants is the energy that is released when the reaction takes place. FAD/FADH2 differ from NAD+/NADH since they are bound tightly (Kd approx 10-7 - 10-11 M) to enyzmes which use them. In addition to ATP, what are the end products of glycolysis? Lv 7. Since two acetyl-CoA molecules for every glucose molecule, these products need to be multiplied by two to obtain the per-glucose yield (i.e., two ATP, six NADH and two FADH2).
