NADH or nicotinamide adenine dinucleotide is a coenzyme present in all living cells. It needs to be reoxidized in order for glycolysis to continue.
One NADH molecule generates approximately 2.5 to 3 ATP through oxidative phosphorylation in the mitochondria.
It becomes NAD. This happens during electron transport where NADH drops off its H+ and electrons to be used in oxidative phosphorylation. NAD now must move to glycolysis or citric acid cycle to regain its hydrogen.
NADH can be recycled to NAD through the process of oxidative phosphorylation in mitochondria. During this process, NADH donates its electrons to the electron transport chain, leading to the generation of ATP and the conversion of NADH back to NAD+.
10 NADH molecules are produced in total. 2 during glycolysis, 2 during link reaction (1 per pyruvate, 2 per glucose molecule), and 6 during the Krebs cycle. None during the electron transport chain.
When a molecule of NAD gains a hydrogen atom, it becomes reduced to form NADH (nicotinamide adenine dinucleotide). This reduction reaction involves the transfer of electrons from the hydrogen atom to NAD, resulting in the formation of NADH.
The process in which coenzymes are reoxidized while conserving energy is typically through oxidative phosphorylation. This occurs in the mitochondria, where reduced coenzymes like NADH and FADH2 donate electrons to the electron transport chain. As electrons are passed along the chain, energy is released and used to pump protons across the mitochondrial membrane, creating a proton gradient. ATP is then synthesized as protons flow back into the mitochondrial matrix through ATP synthase, effectively conserving energy during the reoxidation of coenzymes.

Two molecules of NADH are generated after one cycle of the TCA (Krebs) cycle.
When a molecule of NAD gains a hydrogen atom, it becomes reduced to form NADH (nicotinamide adenine dinucleotide). This reduction reaction involves the transfer of electrons from the hydrogen atom to NAD, resulting in the formation of NADH.
Nadh and ATP
the free energy liberated when electrons are removed from the organic molecules must be greater than the energy required to give the electrons to NAD+
NAD+ is reduced. It becomes NADH.
Lactate is produced in this way. It is a product of the NADH fermentation.
