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
