Electron Transport Chain: Proton Pumps and Coenzyme Q

This lecture delves into the intricacies of the Electron Transport Chain (ETC) in mitochondria, focusing on the role of proton pumps and Coenzyme Q. It covers the sequential movement of electrons, the function of different protein complexes, and the redox potential changes along the ETC. The lecture also explores the chemical biology functions of Coenzyme Q, its structure, and its involvement in electron transport. Additionally, it discusses the path of electrons through the ETC complexes, the pumping of protons across the inner mitochondrial membrane, and the reaction of oxygen with electrons in Complex IV. The presentation includes detailed explanations, diagrams, and a quiz related to mitochondrial function and ETC enzymes.
