Which graph represents the effect of pHk/temp on the velocity of a typical enzymatic reaction (V)

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
Some enzyme acts best in an acid medium other in an alkaline medium. For every enzyme, there is an optimum pH where its action is maximum. Most enzyme show max activity in a pH range of about 6.0 to 7.5. Shifts to the alkaline or acid side rapidly decrease the enzyme activity and finally stops it altogether.
