  • Enzymes and food

    Carbohydrates : Includes glycogen, starch, sucrose, glucose. Enzymes break big sugars into smaller, simpler sugar so that it's easier to chew. Protein : Amino acids, collagen, keratin. Protease enzymes break down proteins in our food into amino acids. Produces stomach, pancreas, small intestine. Lipids : Fats, oil, glycerol. Lipase breaks down lipids in the diet into fatty acids and glycerol.
  • Effects of temp, substrate concentration and pH on enzyme activity.

    Temp: As temp increases so does the rate of enzyme activity. Substrate concentration: As concentration increases so does the activity. pH: As pH value is increased above of decreased below optimum, enzyme activity decreases
  • Lock and key method
    1. Substrate collides with active of enzyme and become attached. 2. Enzyme catalyses breakdown of the substrate. 3. Products release from the active site
  • what is an enzyme?
    a biological catalyst that speeds up a reaction
  • What is an active site?
    where the enzyme binds to a substrate or other substances during a reaction
  • Why are enzymes specific
    Only specific substrate molecules fit into their active site
  • What is protein

    Polymers of amino acids joined by peptide bonds broken down by protease
  • What is lipase
    Enzymes that break down fat into fatty acids and glycerol
