Study Notes
Homeostasis
- The main purpose of homeostasis is to maintain a stable internal environment despite changes in the external environment.
Regulation of Conditions
- An example of a condition regulated by homeostasis is body temperature, which is maintained at around 37°C (98.6°F) in humans.
Enzyme Action
- Cells require the right conditions for enzyme action, including optimal pH, temperature, and substrate concentration, as enzymes are sensitive to changes in these conditions and may become inactive if they are not within a certain range.
Control Systems
- Control systems play a crucial role in homeostasis, as they monitor and respond to changes in the internal environment, making adjustments as needed to maintain homeostasis.
Exceptions
- Blood pressure is not regulated by homeostasis, as it is not a condition that needs to be maintained within a narrow range.
