The stages of cellular respiration that produce NADH but not FADH₂ are glycolysis and pyruvate oxidation.

1. Glycolysis: This is the first stage of cellular respiration. It occurs in the cytoplasm of the cell and does not require oxygen. During glycolysis, one molecule of glucose (a six-carbon sugar) is split into two molecules of pyruvate (a three-carbon compound). In the process, two NADH molecules are produced.

2. Pyruvate Oxidation: This stage occurs in the mitochondria. Each pyruvate molecule from glycolysis is converted into an Acetyl CoA molecule. During this process, one NADH molecule is produced for each pyruvate, so two NADH molecules are produced per glucose molecule.

The citric acid cycle and oxidative phosphorylation both produce FADH₂, so they do not fit the criteria.
