    • 19.1: Electron-Transfer Reactions in Mitochondria
      The page discusses the mitochondrial electron transport system and oxidative phosphorylation, focusing on electron transport complexes I-IV. It describes each complex's structure, function, and electron transfer mechanisms, including cofactors involved. The page details how electron transfer is linked to proton movement, establishing a proton gradient that drives ATP synthesis.
    • 19.2: ATP Synthesis
      This page provides an in-depth exploration of the mitochondrial F0-F1 ATPase, also known as ATP synthase, detailing its structural organization and role in cellular energy production. The page outlines its function in converting ADP and inorganic phosphate into ATP through oxidative phosphorylation, highlighting the structural components, binding change mechanism, and path of proton movement.
    • 19.3: Regulation of Oxidative Phosphorylation
      The page discusses key concepts in biochemistry related to oxidative phosphorylation including the roles of AMP, ADP, and ATP in regulating metabolic pathways, the coupling of electron transport to proton translocation, and the consequences of uncoupling. It emphasizes the integration of metabolic regulation across various pathways and how mitochondria communicate with the nucleus.
