- Respiration
- Carbohydrates
- They are polymers.
- Made from smaller carbohydrates such as sugars.
- Starch is an example of one.
- Starch is synthesised from glucose monomers.
- Plants convert glucose into starch.
- It is a chemical store.
- Starch is synthesised from glucose monomers.
- Carbohydrase enzymes break down carbohydrate.
- They are polymers.
- Proteins
- Proteins are polymers.
- Formed from amino acids.
- 20 different types.
- The order in which amino acids are joined determines the protein.
- Protease enzymes break down proteins to amino acids.
- Lipids
- Fats and oils.
- Good energy store.
- Some animals use them for insulation.
- Synthesised from 3 fatty acids and a glycerol molecule.
- Lipase enzymes break down lipids into fatty acids and glycerol.
- Aerobic Respiration
- With oxygen.
- ATP is used to:
- Synthesise larger molecules.
- Movement
- Staying warm.
- Glucose reacts with oxygen.
- Energy comes from stores in food.
- Respiration takes place in the mitochondria.
- Respiration is an exothermic reaction.
- Energy is transferred to the surrounding by heat.
- The number of mitochondria in cells shows how active it is.
- Anaerobic Respiration
- No Oxygen.
- Glucose is not broken down, lactic acid is produced.
- Produces less ATP molecules per glucose molecule.
- Lactic acid causes cramps.
- Plants takes place in plants when there is no oxygen.
- Produces ethanol and carbon dioxide.
- Carbohydrates
