You discover a previously unknown species of lizard. You want to know more about how it completes glycolysis and what environments it can inhabit. You measure the amount of sugar it uses at 30°C and how much it uses at 20°C. Lowering the temperature has no effect on its rate of consumption. From this data, you can conclude that

Question

Quizplus · Accepted Answer

The Q₁₀ value is a measure of how much a reaction rate changes with a 10°C change in temperature. A Q₁₀ value of over 4 indicates that the reaction rate is very sensitive to temperature. In this case, the rate of glycolysis is not affected by a 10°C change in temperature, so the Q₁₀ value must be less than 4. This suggests that the reactions that make up glycolysis are not very sensitive to temperature, which is characteristic of ectotherms.
