Enzymes

• AMYLASE

  • carbohydrates > sugars
  • produced in:
  • salivary glands, pancreas, small intestine
  • starch > maltose > glucose
• PROTEASE

  • proteins > amino acids
  • produced in:
  • stomach, pancreas, small intestine
• LIPASE

  • fats > fatty acids + glycerol
  • produces in:
  • pancreas, small intestine
  • pH 7/8
• Active site:

  part of the molecule where reaction occurs
• Denature:

  active site of the enzyme changes shape, it can no longer act on the substrate
• Enzyme:

  proteins found in living organisms that speed up the rate of a chemical reaction
• pH:

  level of how acidic or alkaline a substance is
• lock and key mechanism:

  where the substrate fits into the active site
• substrate:

  molecule on which an enzyme acts
• catalyst:

  substance added to a reaction to speed up its rate without being used up in the process
• What do enzymes do?

  • break down or build up molecules
  • the molecule they bind to is called substrate
  • substrate is specific to enzyme
  • substrate fits into active site
