Homeostasis- Biology

define homeostasis

the maintenance of a constant internal environment

what are the important factors that are maintained for mammalian homeostasis

1) temp

2) water potential

3) conc of glucose m

4) blood pH

5) conc of metabolic waste substances

what can happen when temp, water potential and conc of glucose

1) very low temp; metabolic reactions slow down, proteins will get denatured if temp is too high

2) when water potential is too high: water can enter the cells and burst, when water too low: metabolic reactions can slow down or stop

3) conc of glucose too low: lack of glucose causes respiration to slow/stop, depriving cell of energy source, too much glucose: water leaves cell, disturbing metabolism
