Principles of Homeostasis and Negative Feedback Flashcards
1
Q
Define Homeostasis
A
- maintaining a constant internal environment around an optimum despite external change
2
Q
what does homeostasis help to maintain?
A
- stable core temp to provide optimum temp for enzyme activity
- stable blood pH to provide optimum pH for enzyme activity
- stable blood glucose concentration to provide enough glucose for respiration to release energy for metabolic processes in the body
- water potential of the blood
3
Q
what is a negative feedback mechanism
A
- where a change triggers a response which reduces the effect of the change
