An enzyme has a specific pH that it will work the best in. What happens to an enzyme if it is in an environment that is outside of that range?

• It will denature but continue to function effectively

• It will speed up the reaction

• It will denature and function less effectively

• It will slow down the reaction

With what 3 letters do enzymes typically end?

• -ose
• -ase
• -ese
• -tic

The graph shows how enzymes affect reactions in cells. Which statement best summarizes the information shown in the graph?

• Enzymes increase the energy of the reactants.
• Enzymes decrease the energy level of the products.
• Enzyme decrease the activation energy of the reaction.
• Enzymes reverse the direction of the reaction.

Which of the following conclusions can be drawn from this graph?

• The optimum pH of the enzyme is 6.6.
  
• The optimum pH of the enzyme is 5.8
  
• The enzyme’s activity increases as pH increases 5.0 to 9.0
  
• The enzyme’s activity is greater around pH of 8.0 .

• Coenzyme
• Substrate
• Vitamin
• Polypeptide

Enzymes are...
