The electron transport chain is a fundamental pathway in biochemistry, critical for understanding the energy production that powers cellular function.

In this episode, guest host Alex Starks breaks down the intricate process of the electron transport chain (ETC). Building on previous discussions of glucose metabolism, Alex walks through the components that play key roles in the movement of electrons through complexes within the inner mitochondrial membrane. We also cover the functions of coenzyme Q and cytochrome c, as well as oxygen’s critical role in completing the process.
