Digestive Enzymes

• Enzymes


  Protein molecules with a groove on the surface called the active site
• Active site


  Where the substrates will get
• Enzyme action


  1. Substrate perfectly fits into the active site

  2. Enzyme breaks down the substrate into the products
• Proteins


  Long chains of chemicals called amino acids
• Protease enzymes


  Enzymes that break down proteins
• Protein digestion


  1. Protease enzymes break down proteins into individual amino acids

  2. Amino acids are absorbed into the bloodstream
• Starch


  Chain of glucose molecules
• Starch digestion


  1. Enzymes convert starch into sugars

  2. Sugars are absorbed
• Protease enzymes break down proteins
• Starch is broken down by enzymes
• A substrate is a surface or material where an organism grows, lives, or is supported
• Amylase enzymes break down starch and produces sugars.
• Lipases break down fats to produce fatty acids and glycerol.
