Why must a normal body temperature be maintained in order for chemical reactions to be continued at life-sustaining rates?
What will be an ideal response?
If body temperature is too low, chemical reactions slow and eventually stop. If body temperature is too high, chemical reactions speed up and body proteins lose their normal shape, resulting in loss of function.
