2.77a - Thermoregulation




- Homeo - 'same' 
- Stasis - 'fixed point/conditions' 
- Homeostasis - Conditions kept the same/constant 
- when applying homeothermic - it is to do with having the same temperature 
- organisms (e.g. mammals) - when the environmental temperature decreases or increase, then their body temperature remains constant - these are homeothermic organisms - carry out the process - thermoregulation 
- other organisms body temperature, varies with the environmental temperature 


2.9 - recall - rates of reactions 
- maximum rate of reaction is achieved by an optimum temperature for that enzyme 


- both graphs are related as the optimum temperature for the enzyme is approximately the same as the temperature at which the mammals maintain their body conditions
