Respiration

• • Aerobic/Cellular respiration- living things get energy from their food in this process.
  • For aerobic respiration take place cells need a supply of glucose and oxygen.
• Respiration is an Exothermic reaction because it releases energy.
• Oxygen - Aerobic respiration because of the glucose molecule there’s more energy

  
• • Shortage of oxygen : Anaerobic respiration
  • Less energy because the glucose is not fully oxidised.

  
• Yeast cells.

  this ethanol is produced by fermentation (converting glucose to alchol)
