Answer:
Water controls body temperature.
Explanation:
One of the functions of water is to regulate the internal temperature of the body in response to the external temperature. Sweat is the main means by which water prevents the human body from too much heat (over heating) when the outside temperature is too high. We must allow the sweat to evaporate to maintain stable body temperature.
Pepsin functions best in acidic environments and is often found in an acidic environment, particularly those with a pH of 1.5 to 2".
"Trypsins have an optimal operating pH of about 8".
It seems that the highest level of activity for the two if they were in the same environment would have to be midway between their optimum range - about pH 5
