🔬 Deep Dive: Homeostasis Definition
Homeostasis = the regulation of the internal conditions of a cell or organism to maintain optimum conditions for function, in response to internal and external changes.
What needs to be controlled:
- Body temperature: Enzymes work best at 37°C — too hot they denature, too cold reactions are too slow
- Blood glucose concentration: Cells need glucose for respiration but too much damages cells
- Water levels: Cells need the right amount of water for reactions; maintains osmotic balance
