RESPIRATION
- Aerobic
  - glucose + oxygen = carbon dioxide + water + energy
    - Glucose = result of digestion
    - Carbon dioxide released as waste product
  - Respiration using oxygen
  - Plants and animals all the time
  - Reactions happen in mitochondria
  - Reactions controlled by enzymes
- Anaerobic
  - Exercise without oxygen
  - glucose = energy + lactic acid
  - Incomplete break down of glucose
  - Muscle fatigue
    - Muscles get tired & stop contracting efficiently
    - Lactic acid builds up in the muscles
  - Oxygen debt
    - "Repay" oxygen that didn't get to muscles in time because lungs etc. couldn't keep up with the demand
    - Blood flows through muscles to remove lactic acid (oxidising it)
    - = high breathing rate after exercise
- Process of releasing energy from glucose which goes on in every cell
- Exercise
  - Heart rate increases
    - Supply blood to working muscles faster
    - CO2 needs to be removed quicker
  - Rate/depth of breathing increases
    - Meet the extra demand for oxygen
  - Glycogen
    - Some glucose from food stored as glycogen
    - Some of the stored glycogen converted back to glucose for more energy

This is a concise mind map that makes good use of colour to separate the key topics. This topic is found in most GCSE science and biology specifications. Research show that it aids memory if images are added to the map so download and get creative.
