ANIMALES POIQUILOTERMOS PDF

Physiology[ edit ] Sustained energy output of a poikilotherm a lizard and a homeotherm a mouse as a function of core body temperature. The homeotherm has a much higher output, but can only function over a very narrow range of body temperatures. Poikilotherm animals must be able to function over a wider range of temperatures than homeotherms. The speed of most chemical reactions vary with temperature, and in order to function poikilotherms may have four to ten enzyme systems that operate at different temperatures for an important chemical reaction. Frogs are a notable example of this effect, though their complex development is also an important factor in their large genome. As they do not use their metabolisms to heat or cool themselves, total energy requirement over time is low.
