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
