Question

enzyme
2 4 6 8 10 12 14
ph
the enzyme activity for both a and b increases as the ph increases.
the activity of b stops at a ph of 10.
the optimum ph for both reactions a and b is around 4.5.
the optimum ph for reaction a is approximately 6.

Explanation:

Analyze the graph. Enzyme A peaks around pH 6. Others are incorrect based on graph trends.

Answer:

The optimum pH for Reaction A is approximately 6.
