The maintenance of an internal environment around an optimum value
1 of 7
What should core temp not remain too low?
Too low would mean enzymes and substrate molecules have insufficient kinetic energy
2 of 7
Why should core Temp not remain too high?
Proteins denature
3 of 7
Why is it important that blood ph remains stable?
Maintains a stable rate of enzyme controlled reactions
An acidic pH means the H+ ions would interact with the hydrogen bonds in the tertiary structure of proteins
4 of 7
Why is it important that blood glucose concentration remains stable?
To maintain a constant blood water potential to prevent osmosis lysis
5 of 7
What is negative feedback?
Self-regulatory mechanisms return internal environment back to optimum when there are fluctuations
6 of 7
What is positive feedback?
A fluctuation triggers changes that results in an even greater deviation from the normal level
