- - - - Carry female DNA to nourish the embryo
      - Contains nutrients in cytoplasm
      - Haploid nucleus
      - Membrane changes structure to stop sperm getting in
    - - Transport male DNA to female egg
      - Long tail so it can swim to the egg
      - Lots of mitochondria to provide energy
      - Has acrosome in the head of the sperm to store enzymes
      - Haploid nucleus
- - - - Changing the temperature changes the rate of reaction
      - If it gets too hot the bonds break and the substrate denatures
      - When the substrate changes shape it cannot fit into the active site
    - - pH affects enzyme
      - pH interferes with bonds holding enzyme together and the shape denatures
      - Enzymes optimum temperature is 7
