Enzyme maltase of human gut acts on food at

Options

A. pH less than 7,changes maltose to fructose
B. pH more than 7,changes maltose to glucose
C. pH less than 7, changes strarch to maltose
D. pH less than 7,changes starch to maltose.

Answer

### Step-by-Step Solution:

1. **Understanding the Role of Maltase**: Maltase is an enzyme found in the human gut that specifically acts on maltose, a disaccharide formed from the digestion of starch.

2. **Identifying the pH Conditions**: The activity of maltase is influenced by the pH of the environment in which it operates. It is important to note that different pH levels can affect the enzyme's function.

3. **Effect of pH on Maltase**:
- **pH Less than 7**: At acidic pH levels (less than 7), maltase can convert maltose into fructose.
- **pH More than 7**: At alkaline pH levels (more than 7), maltase converts maltose into glucose.

4. **Location of Enzyme Action**: Maltase is primarily active in the small intestine (duodenum), where the pH is typically more than 7 due to the presence of bicarbonate ions secreted by the pancreas.

5. **Conclusion**: Therefore, the enzyme maltase of the human gut acts on food at a pH more than 7, changing maltose into glucose.

### Final Answer:
The enzyme maltase of the human gut acts on food at a pH more than 7, changing maltose to glucose.
