Question

enzymes have an optimum within which they function best.
what is the optimum ph for salivary amylase?
choose
which enzyme works best in an acidic ph?
choose
at what ph range is alkaline phosphatase active?
choose

Explanation:

Step1: Analyze the graph for salivary amylase

Locate the peak of the salivary amylase curve on the graph. The peak represents the optimum pH.

Step2: Determine the pH value at the peak

From the graph, the peak of the salivary amylase curve is at pH 7.

Step3: Identify the enzyme that works best in acidic pH

Look at the pepsin curve. Pepsin's peak is in the acidic range (pH 2).

Step4: Find the pH range for alkaline phosphatase

Locate the alkaline phosphatase curve. Its peak is in the alkaline range (pH 9 - 10).

Answer:

• Optimum pH for salivary amylase: 7
• Enzyme that works best in acidic pH: Pepsin
• pH range for alkaline phosphatase: 9 - 10
