Biology (B3 (Key words (Patheogen (Small particles which cause illness…

- - - - Small particles which cause illness main types are viruses and bacteria
    - - Easily enter blood vessel wall and ingest patheogens or release enzymes which destroy them
    - - Chemicals within Pathogens which are foreign to the body
    - - Are proteins which neutralise patheogens
- - - - Meaning they increase the rate at which chemical reactions take place without being used up
        
        Enzymes are proteins that are folded into complex shapes .The place were the substrate and enzyme fit is called the active site.
        
        Over a certain temperature an enzyme becomes denatured meaning that a substrate cant fit
    - - It is present in the pancrease ,small intestine and salivary gland
    - - Present in the stomach pancrease and small intestine
    - - Present in the pancrease and small intestine
    - - Protease is used to predigest baby food
      - Protease is used to remove fatty oil protein based stains within detergents
- - - - Push and move mucas
        
        Have a thin layer of hairs called cilla
    - - Carry oxygen around the body
        
        Do not have a nucleus to increase volume of haemoglobin-contains lots of haemoglobin a pigment which carries oxygen
    - - Absorbs water and minerals from soil
        
        Has a long extension increasing surface area for absorption
    - - Transports water in the plant -supports the plant
        
        No cytoplasm or end cells allowing the water to flow freely
- - - - glucose + oxygen → carbon dioxide + water (+ energy)
  - - - 6CO2+6H20>>>H12O6+6O2
  - - - Used when not enough oxygen for aerobic respiration
        
        glucose → lactic acid
