Master Oxidative Phosphorylation and Chemiosmosis fast ⚡ – clear explanations, OCR-aligned.
You’ll cover
• The role of oxidative phosphorylation as the final stage of aerobic respiration.
• How reduced NAD and reduced FAD donate electrons to the electron transport chain.
• The movement of electrons through a series of oxidation–reduction reactions.
• How energy released from electron transfer drives proton transport across the inner mitochondrial membrane.
• The formation of an electrochemical gradient of hydrogen ions.
• How chemiosmosis drives ATP synthesis through ATP synthase.
• Why oxygen acts as the final electron acceptor and forms water.
What’s included
• Labelled diagram showing the processes of oxidative phosphorylation across the inner mitochondrial membrane.
• Model exam-style explanation summarising oxidative phosphorylation.
• Table outlining the main substances involved in oxidative phosphorylation and their roles.
• Table comparing the key principles of chemiosmosis in mitochondria and chloroplasts.
