enzymes

• How do enzymes affect metabolism?


  - Speed up metabolic reactions
• What is the active site?


  The active site is the region on the enzyme where the substrate binds.
• What is the substrate?


  The reactant that an enzyme acts on
• How does temperature and PH affect enzyme activity?


  - Enzymes reach opotimal activity at certain temps

  - Too hot of temps can lead to changing the shape of the active site so the enzyme becomes denatured
• What is the lock and key theory?


  A substrate is specific to one enzyme because of the specific shape of its active site (like a key fitting a lock)
• What is the purpose of digestive enzymes?


  Convert food into small soluble molecules that can be absorbed into the bloodstream
• What is a carbohydrase?


  - Carbohydrates -> simple sugars
• What is amylase?


  -A type of carbohydrase

  - Breaks down starch -> SS
• Where is amylase produced?


  Salivary glands, pancreas, small intestine
• What is protease?


  - Breaks down proteins into amino acids
• Where is protease produced?


  - Pancreas

  - Small intestine

  - Stomach
• What is lipase?


  - Breaks down fats into fatty acids and glycerol
