Webenzymes enable metabolic reactions to occur at high rates at biological temperatures. From the standpoint of adaptation to different environmental temperatures, it has been … WebMost ectotherms do regulate their body temperature to some degree, though. They just don't do it by producing heat. Instead, they use other strategies, such as behavior—seeking sun, shade, etc.—to find environments whose temperature meets their needs. Each of the categories above is called a trophic level, and it reflects how many tra…

WebOct 24, 2024 · For enzymes to function properly, they must be able to maintain their three-dimensional shape. When temperatures increase, the kinetic energy of molecules also increases, which causes them to vibrate more. This increased vibration can cause enzymes to change shape, which can render them inactive.
