Introduction to cellular respiration and redox reactions in AP Biology.
Khan Academy
NADH, a molecule produced during cellular respiration, gets oxidized and releases electrons. These electrons pass through a series of acceptors in the electron transport chain, releasing energy. This energy pumps hydrogen protons across a membrane, creating a gradient.
Khan Academy
Explore how glucose oxidation contributes to ATP synthesis, understand the roles of NADH and FADH2, and learn why ATP yield varies. Dive into the electron transport chain and the proton gradient's role in ATP synthase.

To see how a glucose molecule is converted into carbon dioxide and how its energy is harvested as ATP and NADH / FADH 2 in one of your body's cells, let’s walk step by step through the four stages of cellular respiration. Glycolysis. In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it ...

Oxidation–reduction (redox) reactions (article) | Khan Academy
Oxidation–reduction reactions, commonly known as redox reactions, are reactions that involve the transfer of electrons from one species to another. The species that loses electrons is said to be oxidized, while the species that gains electrons is said to be reduced.

Pyruvate oxidation | Cellular respiration (article) - Khan Academy
Overall, pyruvate oxidation converts pyruvate—a three-carbon molecule—into acetyl CoA —a two-carbon molecule attached to Coenzyme A—producing an NADH and releasing one carbon dioxide molecule in the process.
