Question

Which is the most accurate conclusion, based on the data above?

A High concentrations of the enzyme catalase inhibit the production of oxygen.
B Activity of the enzyme catalase is greatest at a concentration of 100 units/mL.
C High concentrations of the enzyme catalase create more hydrogen peroxide.
D Activity of the enzyme catalase is greatest at a concentration of 20 units/mL.

Answer 1

Answer: B. Activity of the enzyme catalase is greatest at a concentration of 100 units/mL.
Explanation: As seen in the graph, the rate of oxygen production is highest at the catalase concentration of 100 units/mL. At concentrations above and below this level, the rate of oxygen production decreases. Therefore, it can be concluded that the activity of the enzyme catalase is greatest at a concentration of 100 units/mL. The other options do not accurately reflect the trend in the data presented in the graph.
