At various chemical reactions, the NAD+ picks up an electron from glucose, at which point it becomes NADH. Then NADH, along with another molecule flavin adenine dinucleotide (FADH2) will ultimately transport the electrons to the mitochondria, where the cell can harvest energy stored in the electrons.

NADH stands for nicotinamide adenine dinucleotide hydrogen. The chemical is naturally present in the body and is involved in various metabolic processes.

The functions of NADH can be given as:

  • NADH is involved in the electron transport chain. It is a high-energy electron carrier that transports the electron generated in glycolysis and Krebs cycle to the Electron Transport Chain.

  • NADH is used to generate ATP by oxidative phosphorylation. NADH is a reduced form of NAD+, which is produced during the Tricarboxylic acid cycle and glycolysis.

Thus, the NADH is a high-energy electron carrier that is involved in the production of ATP.
