  • Respiration is the process of releasing energy from the breakdown of glucose. Respiration takes place in every living cell, all of the time and all cells need to respire in order to produce the energy that they require.

What is the energy used for?

  • The energy produced during respiration is used in many different ways, some examples of what it is used for are:
  • Working your muscles
  • Growth and repair of cells
  • Building larger molecules from smaller ones i.e. proteins from amino acids
  • Allowing chemical reactions to take place
  • Absorbing molecules in active transport
  • Keeping your body temperature constant
  • Sending messages along nerves

Types of Respiration

  • There are two main types of respiration, aerobic and anaerobic we will look at each one of these in detail now.
  1. Aerobic Respiration
  • Aerobic means “with air”. This type of respiration needs oxygen for it to occur so it is called aerobic respiration. The word equation for aerobic respiration is:
