3. Anaerobic respiration
• When the final electron acceptor is anything but oxygen.
• The final electron acceptor is an inorganic molecule such as nitrate,
sulphur etc.
• Less efficient as compared to aerobic respiration.

5. Energy calculation of anaerobic respiration:
• Anaerobic respiration results in the production of 2ATP molecules.
• The H+ ions that are removed during this process are usually released into the
surrounding cellular respiration.
• This process regenerates NAD+ for glycolysis to continue in the absence of
oxygen.
7. Chemiosmotic theory:
• Proposed by Peter Mitchell in the 1960s.
• Chemiosmotic theory: Electron transport and ATP
synthesis are Coupled by a proton gradient across the
inner mitochondrial membrane.

9. Summary
• Anaerobic respiration is a metabolic process that occurs in the absence of
oxygen. There are two main pathway – Lactate fermentation and Alcoholic
fermentation.
• Rate of respiration depends on several factors such as temperature, O2,CO2,
light, water, injury, chemicals etc.
• Chemiosmotic Theory explains the synthesis of ATP through the action of ATP
synthase.
