• When does anaerobic respiration occur?

  When the body is in debt of oxygen

  Eg.whilst exercising
• Word equation for anaerobic respiration

  Glucose ----> lactic acid
• Why do we favour aerobic over anaerobic respiration?

  There is an incomplete breakdown of glucose as there is a lack of oxygen to oxidise it.This means that not all of its' energy is released.

  Anaerobic respiration produces lactic acid as a bi-product, which can build up and damage cells and lead to oxygen debt and therefore it need removing.
• What is the formulae for anaerobic respiration in yeast and plants?

  Glucose ---> Ethanol + Carbon Dioxide
• What is the anaerobic respiration of yeast called?

  Fermentation
• Where does anaerobic respiration occur?

  In the cytoplasm of living cells.
• What is oxygen debt?

  The amt of oxygen required to break down the lactic acid.
