Metabolic rate of a fish was measured at 10 deg C and 20 deg C. The values were 4 mL O2/kg/hr at 10 deg C and 9 mL O2/kg/hr at 20 deg C. Q10 is the factor by which rate increases with a 10 deg C rise.
What is the approximate Q10 of this fish?
- A
About 13
- Bcheck_circle
About 2.25
- C
About 5.0
- D
About 0.44
Explanation
Q10 = R(T2)/R(T1) = 9/4 = 2.25, typical of biological systems where rates roughly double per 10 deg C rise.
