NADH is produced during all stages of cellular respiration except the electron transport chain.

Here's a step-by-step breakdown:

a. Glycolysis: This is the first stage of cellular respiration, which occurs in the cytoplasm. During glycolysis, glucose is broken down into two molecules of pyruvate. This process produces a net gain of 2 NADH molecules.

b. Pyruvate Breakdown: This stage occurs in the mitochondria. Each pyruvate is broken down into an Acetyl CoA molecule. This process produces 1 NADH per pyruvate, so 2 NADH for the two pyruvates derived from one glucose molecule.

c. Citric Acid Cycle (also known as Krebs Cycle or TCA Cycle): This stage also occurs in the mitochondria. Each Acetyl CoA enters the cycle to be further broken down, producing 3 NADH per cycle. Since there are two cycles per glucose molecule (one for each Acetyl CoA), this stage produces a total of 6 NADH.

d. Electron Transport Chain: This is the final stage of cellular respiration, which occurs in the inner mitochondrial membrane. Here, the NADH produced in the previous stages is used, not produced. The electrons from NADH are transferred through a series of proteins in the membrane, ultimately leading to the production of ATP.
