The salivary amylase shows maximum digestive action at pH `"______"`

Options

A. `3.6`
B. `7.5`
C. `8.5`
D. `6.8`

Answer

To determine the pH at which salivary amylase shows maximum digestive action, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Enzyme**: Salivary amylase is an enzyme produced by the salivary glands in the mouth. Its primary function is to initiate the digestion of carbohydrates.

2. **Understand the Function**: Salivary amylase breaks down carbohydrates into simpler sugars. This process is crucial as it starts the digestion of food even before it reaches the stomach.

3. **Determine the Optimum pH**: Enzymes have specific pH ranges where they function most effectively, known as optimum pH. For salivary amylase, the optimum pH is around 6.8.

4. **Evaluate the Options**: If provided with multiple-choice options, we can eliminate those that do not match the optimum pH. For instance:
- pH 3.6 (incorrect)
- pH 7.5 (incorrect)
- pH 8.5 (incorrect)
- pH 6.8 (correct)

5. **Conclusion**: The salivary amylase shows maximum digestive action at pH 6.8.

### Final Answer:
The salivary amylase shows maximum digestive action at pH **6.8**.
