The graph below shows how the activity of an enzyme changes over a range of pH values. 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 continually increases as pH increases from 5.0 to 9.0
• The enzyme’s activity is greater around pH of 8.0 than around pH of 5.0.
