    Study Notes

    Respiratory Chain in Eukaryotic Cells

    • Occurs in the mitochondrial inner membrane

    Mechanism of Proton Pumping

    • Driven by the energy released from the transfer of electrons through a series of electron transport chain complexes

    Primary Function of the Respiratory Chain

    • Generates ATP (adenosine triphosphate) from the energy released from the electron transport chain

    ATP Synthesis

    • ATP is produced from ADP (adenosine diphosphate) and inorganic phosphate (Pi) through the process of chemiosmosis
    • ATP synthase plays a crucial role in this process

    Role of ATP Synthase

    • Catalyzes the phosphorylation of ADP to ATP using the energy generated from the proton gradient
