How does temperature affect the metabolism of cockroaches or ectotherms since enzymes work at optimum levels?

The enzymes in ectothermic animals have been adapted through natural selection to function at the range of temperatures experienced by these organisms. In general, the reaction rate of an enzyme catalyzed reaction increases by a factor of 2-3 for each 10 degree Celsius rise in temperature. Above about 40 degrees Celsius, enzymes will start to denature (unfold) and become non-functional.
