In this video, we will explain how the electron transport chain works and how it produces most of the ATP in eukaryotic cells. The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP. It uses the energy from the electrons donated by NADH and FADH2, which are produced in the citric acid cycle, to pump protons across the inner mitochondrial membrane and generate a proton motive force. It occurs in the inner membrane of mitochondria. It is composed of 4 main protein complexes: Complex I, Complex II, Complex III, and Complex IV. Each complex transfers electrons to a mobile electron carrier and pumps protons from the matrix to the intermembrane space. The final electron acceptor is molecular oxygen, which is reduced to water. The proton gradient drives the synthesis of ATP by ATP synthase, which uses the energy from the proton flow to convert ADP and Pi into ATP. Watch this video to learn more about the electron transport chain and its role in cellular respiration and photosynthesis.
