If Q10 for an enzyme E is 2.00, what is the rate of enzyme activity at 20°C and 40°C?

20°C: 26

40°C: 104

20°C: 23

40°C: 43

20°C: 26

40°C: 52

13. The rate will not change.

Answer explanation

Q10 = rate of reaction at (T + 10˚C)/rate of reaction at T˚C

At 20°C: 2 = x/13

13 * 2 = x

26 = x

At 30°C: 2 = x/26

26 * 2 = x

52 = x

At 40°C: 2 = x/52

52 * 2 = x

104 = x
