Anaerobic respiration

• Location of anaerobic respiration

  - Cytoplasm

  -Glycolysis is only source of ATP
• Anaerobic respiration in plants & microbes

  - Pyruvate produced in glycolysis is reduced to form ethanol and CO2

  - Pyruvate gains hydrogen from reduced NAD

  - Reduced NAD oxidised to NAD so can be reused in glycolysis

  - 2 ATP produced
• Anaerobic respiration in animals

  - Pyruvate produced in glycolysis is reduced to form lactate

  - Pyruvate gains hydrogen from reduced NAD

  - Reduced NAD oxidised to NAD so can be reused in glycolysis

  - 2 ATP produced
• Other respiratory substances


  - Fatty acids and amino acids can enter the Krebs cycle for continued ATP synthesis
• Lipids as respiratory substances

  - Glycerol from lipid hydrolysis converted to acetylcoenzyme A an enter the Krebs cycle
• Proteins as respiratory substances

  - Amino acids from protein hydrolysis can be converted to intermediates within Krebs
