Question

mini - quiz: ph and enzymes
what is the optimal ph for the enzyme shown below?
a. 8
b. 9
c. 7
d. 10
rate of enzyme - catalyzed reaction at varying ph levels

Explanation:

Step1: Identify peak of graph

The optimal pH is where the rate of enzyme - catalyzed reaction is highest.

Step2: Read x - value at peak

From the graph, the rate of reaction is highest at pH = 8.

Answer:

A. 8
