- Homeostasis = Homeo (refers to the idea that something being the same) stasis (refers to a fixed point or a set of conditions) --> The idea that conditions are kept the same or constant.
- Homeothermic = maintaining the same temperature.
- Some organisms (e.g. mammals) when the environmental temperature either increases or decreases, then their body temperature remains constant.
- These are Homeothermic organisms that carry out the process of Thermoregulation (an example of Homeostasis)
- Other organisms body temperature vary with the environmental temperature.
- Mammals maintain a constant body temperature because:
+ Enzymes work best at the optimum temperature.
+ The optimum temperature for the enzyme reaction is the approx. the same as the temperature that which the mammals maintain their body conditions.
