What is the difference between oxidation of NADH and reduction of NAD+?
What happens in each case?
Dear student
NAD stands for nicotinamide adenine dinucleotide. It exist in two forms: NAD+ and NADH and they are collectively referred to as redox couple.
Redox reactions involve the gaining or loss of electrons. If something becomes oxidized, it’s losing electrons. Thus oxidation of NADH gives NAD+ and if something is reduced, it is gaining electrons, reduction of NAD+ gives NADH.
The conversion of NAD+ to NADH, and vice versa, are essential reactions in creating ATP during cellular respiration.

In glycolysis and the Krebs cycle, NADH molecules are formed from NAD+.
Thus both molecules play a similar role.
