RESPIRATION

RESPIRATION

ANAEROBIC
1. Anaerobic respiration is used for short quick powerful movement
2. glucose --> lactic acid or C6H12O6 --> 2C3H6O3
3. Takes place in the cytoplasm not the mitochondria
4. OXYGEN DEBT
  1. Lactic acid causes cramp
  2. Once oxygen can be supplied, lactic acid is then broken down fully in the liver forming carbon dioxide and water
  3. The amount of oxygen need to do this is known as your OXYGEN DEBT
  4. This is why you keep breathing deeply after exercise.
AEROBIC
1. aerobic respiration uses OXYGEN
2. Glucose + Oxygen --> Carbon dioxide + Water or C6H12O6 + 6O2 --> 6CO2 + 6H2O
3. Uses of energy in respiration: 1. Muscle contractions. 2. Active transport. 3. Protein synthesis. 4. control of body temperature
4. CELL RESPIRATION
  1. Respiration is NOT BREATHING. Respiration IS the release of energy in cells
  2. Energy comes in many different forms
  3. Our energy comes from food which contains chemical energy
  4. The energy is converted (transduced) into other forms during respiration
5. takes place in the mitochondria
EFFECTS OF EXERCISE
1. when you exercise, your heart has to beat faster so that more blood can flow around and the body and reach your cells to give them the energy and oxygen needed to complete a certain activity
FERMENTATION
1. FERMENTATION IN YEAST
  1. Anaerobic respiration uses NO OXYGEN
    1. This is why we use yeast to make bread rise or alcoholic drinks
      1. NOTE – Yeast can do aerobic respiration too
  2. Glucose → Ethanol + Carbon dioxide C6H12O6 → 2C2H5OH + 2CO2
