為何生物一定要在一定的體温下才可生存

since inside our body we have a lots of enzymes.....n these enzyme can only work in a specific range of temperature...if the temperature over the range , out enzyme may denature(變形).......so we have to keep our body in around 37degree celcious........

therefore,those 冷血動物因為冬天體温低,冬眠 can reduse the rate of heat loss.........and 發熱is a dangerous illness...when ppl said 燒到105度會好危險.....就係咁解啦.........
