Question

15 a student investigates the effect of ph on enzyme activity. which result is most likely supported by data?
maltase enzyme activity in different ph solutions
a enzyme activity is highest at an optimal ph, then decreases if the ph changes
b enzyme activity increases steadily with higher ph
c ph has no effect on enzyme function
d enzymes only work in acidic conditions

Explanation:

The graph shows maltase enzyme activity peaks at a specific pH (the optimal pH), and activity decreases as pH moves away from this optimal value in either direction. Option A matches this trend, while options B, C, and D contradict the data shown in the graph.

Answer:

A. Enzyme activity is highest at an optimal pH, then decreases if the pH changes
