Question

Why nadh oxidation and atp production enerrgetically fabourable?

Answer 1

NADH produces 3 ATP during the ETC (Electron Transport Chain) with oxidative phosphorylation because NADH gives up its electron to Complex I, which is at a higher energy level than the other Complexes. ... Protons still have been pumped, enough to fuel 2 ATP created by ATP synthase.

Answer 2

Since two ATPs were required to prime the initial reactions, the net gain from glycolysis is two ATP molecules. In addition to producing ATP, glycolysis converts two molecules of the coenzyme NAD+ to NADH. In this reaction, NAD+ acts as an oxidizing agent that accepts electrons from glyceraldehyde-3-phosphate.
