The optimum reaction rate of a particular enzyme occurs at pH 7.3 at 37°C. This reaction would probably proceed faster by
A) increasing both temperature and pH.
B) decreasing the pH and increasing the temperature.
C) increasing the pH and maintaining the temperature at 37°C.
D) increasing the temperature to 38°C and keeping the pH at 7.3.

Question

Quizplus · Accepted Answer

Enzymes have specific optimal conditions under which they function best. Since the optimum pH is already given as 7.3, altering the pH could potentially decrease the enzyme's activity. Increasing the temperature slightly from 37°C to 38°C could increase the reaction rate, assuming it does not denature the enzyme or exceed its temperature optimum.
