Oxidative phosphorylation

• Where does oxidative phosphorylation occur?

  Mitochondrial inner membrane
• What structures are found on the mitochondrial inner membrane?

  Enzymes and carrier proteins
• How many reduced NAD and FAD are produced from one glucose molecule?

  Ten reduced NAD and two reduced FAD
• What is the primary function of oxidative phosphorylation?

  Produce ATP
• What are the three key parts of oxidative phosphorylation?

  Electron transfer chain, protein movement, ATP synthase
• What happens to hydrogen atoms in oxidative phosphorylation?

  They split into protons and electrons
• What is created as protons are transported to the intermembrane space?

  An electrochemical gradient
• How do protons move back through the membrane?

  Through ATP synthase
• Why is oxygen important in oxidative phosphorylation?

  It is the final electron acceptor
• What is produced when oxygen accepts electrons and protons?

  Water
• What is the significance of oxygen in respiration for essay questions?

  It allows for efficient ATP production
• What is the role of reduced coenzymes in oxidative phosphorylation?

  Carry hydrogen to the final step
• How do protons move through ATP synthase?

  By facilitated diffusion
• Why is the electrochemical gradient important in ATP production?

  It drives protons through ATP synthase
• What is the overall yield of ATP from one glucose molecule in aerobic respiration?

  Approximately 30-32 ATP
