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
