Enzymes

• Biological catalyst?

  Speeds up the reaction
• What is enzymes made up?

  Proteins
• Does active site have a specific shape?


  Yes
• Is an Enzyme changed or unchanged?


  Unchanged
• In enzymes, speed is affected by?

  Temperature

  pH

  Concentration of substrate

  Presence of inhibitors
• Enzymes are biological catalyst that:

  decrease the activation energy of chemical reaction
• What is the role of an enzyme?

  Breaking down large molecules into small molecules
• Enzymes are specific in their action because

  They have a unique three dimension strucutre
• Do enzymes increase the rate of chemical reaction by lowering the activation energy?


  Yes
