Enzymes

• Enzymes

  Catalysts that speed up the rate of a chemical reaction without being changed or used up in the reaction
• Biological Catalysts


  Enzymes that are made in living cells and speed up the rate of chemical reactions without being changed
• Metabolic Reactions


  All the reactions that keep an organism alive
• Enzyme-substrate complex


  When the substrate attaches to the active site of the enzyme
• Optimum temperature


  The temperature at which enzymes work the fastest, usually 37⁰C
• Denaturation


  The loss of shape and activity of an enzyme due to high temperatures or extreme pH
• Enzyme activity


  The rate at which an enzyme catalyzes a reaction
• Substrate


  The molecule that gets broken down or joined together in the reaction
• Active Site


  The area in the enzyme where the substrate attaches
• Lock and Key hypothesis


  The idea that the active site of the enzyme is a complementary shape to the substrate
• Amylase


  An enzyme that breaks down starch
• ph.


  A measure of the acidity or alkalinity of a solution
