About this listen

Dive into the powerhouse of the cell as we unpack the electron transport chain (ETC)—a series of protein complexes that transform the energy from food into ATP, the fuel for nearly all cellular functions. We’ll explore how electrons from NADH and FADH₂ travel through the chain, sparking a cascade that creates a proton gradient across the mitochondrial membrane. This gradient powers ATP synthesis, enabling cells to perform essential tasks. From energy production to protection against reactive oxygen species, the ETC plays a central role in cellular health and efficiency. Join us as we explore how this microscopic assembly line powers life.
