How temperature and pH affect enzymes

• What are the two main factors that affect enzyme activity?

  Temperature and pH.
• What does the term 'optimum' mean for enzyme temperature?

  highest enzyme activity, best
• What is the optimum temperature of enzymes in the human body?

  around 37-38 degrees celcuis
• What is pH?


  measure of acidity
• Can enzymes be reused?

  Yes
• Explain how high or low pH can cause an enzyme to denature.

  breaks the bonds, causes active site to change shape, meaning active site will no longer be complementary to the substrate, meaing it can no longer form an enzyme-substate complex.
• What is optimal pH?

  pH which enzyme works best
• What happens if a pH is to high/low?

  lowers rate of reaction
• What does the term denatured mean?

  enzyme wont bind to the substrate
