Enzyme maltase in human gut acts on food at a pH of-

Options

A. More than seven to change starch into maltose
B. Less than 7 to change starch into maltose
C. More than 7 to change maltose into glucose
D. Less than 7 to change maltose into glucose

Answer

**Step-by-Step Solution:**

1. **Understanding Maltase and Its Function**:
- Maltase is an enzyme that catalyzes the breakdown of maltose, a disaccharide, into two molecules of glucose, which are monosaccharides.

2. **Location of Maltase Activity**:
- The activity of maltase occurs in the human gut, specifically in the small intestine, where it is secreted as part of the intestinal juice.

3. **pH Environment in the Intestine**:
- The intestinal juice has an alkaline pH, which is typically greater than 7. This alkaline environment is essential for the activation of various digestive enzymes, including maltase.

4. **Role of pH in Enzyme Activity**:
- Enzymes have specific pH ranges in which they are most active. For maltase, the alkaline pH in the intestine is necessary for its optimal function.

5. **Conclusion**:
- Given that maltase acts in the intestinal juice, which is alkaline, we conclude that maltase operates at a pH of more than 7 to convert maltose into glucose.

**Final Answer**: The enzyme maltase in the human gut acts on food at a pH of more than 7.
