Aerobic respiration

• Respiration


  A chemical reaction which releases energy from food
• Respiratory system


  Exchanges the gases involved in respiration
• Seven life processes


  • Movement
  • Respiration
  • Sensitivity
  • Growth
  • Reproduction
  • Excretion
  • Nutrition
• Respiration


  Provides the energy required for the seven life processes
• Respiration


  Provides energy for muscle contraction, nerve impulses, cell division and protein synthesis
• Respiration


  Releases energy in the form of heat to maintain body temperature
• Aerobic respiration


  Involves chemical reactions that break down nutrient molecules in living cells to release energy in the presence of oxygen
• Aerobic respiration


  Glucose + oxygen → carbon dioxide + water + energy in the form of ATP
• ATP


  The energy currency of the cell that temporarily stores energy in a high energy bond
• Mitochondria


  • Structures in the cytoplasm of all cells where aerobic respiration takes place
  • The inner membrane is folded inwards, providing a large surface area for the attachment of enzymes which catalyse the process of respiration
