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

on an enzyme, the site that attaches to a substrate

• Polypeptide 
• Base
• Substrate 
• Active site 

Which of the following environmental changes could denature an enzyme?

• too high a concentration of substrate

Enzymes act by

• providing energy to a chemical reaction

• removing energy from a chemical reaction

• lowering the amount of energy needed for a chemical reaction

• eliminating the need for energy in a chemical reaction
