Proton Pumping by ETC

The video explores the respiratory chain complexes, focusing on their roles in proton pumping and ATP synthesis. It explains the structure of the mitochondrial membrane and how proton gradients are formed. The video highlights the importance of NADH and FADH2 in powering ATP synthase, emphasizing the ultimate goal of metabolism to produce ATP. The process of rotational catalysis in ATP synthase is also introduced.
