If stomach doesnot produce HCl then which enzyme will work for longer period than its usual time-

Options

A. Pepsin
B. Ptyalin
C. Rennin
D. Trypsin

Answer

To solve the question of which enzyme will work for a longer period if the stomach does not produce HCl, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Role of HCl in the Stomach:**
- Hydrochloric acid (HCl) is essential for creating an acidic environment in the stomach. This low pH is necessary for the activation and functioning of certain digestive enzymes.

2. **Identifying the Enzymes:**
- The question provides several enzymes: Pepsin, Tylenol (Amylase), Renin, and Trypsin. We need to analyze how each of these enzymes functions in relation to HCl.

3. **Analyzing Pepsin:**
- Pepsin is an enzyme that is secreted in an inactive form (pepsinogen) and is activated by HCl. It works optimally in the acidic environment of the stomach. If HCl is not produced, Pepsin will not be activated and therefore will not work.

4. **Analyzing Tylenol (Amylase):**
- Tylenol, or salivary amylase, is produced in the mouth and begins the digestion of starch. It functions optimally at a neutral pH. Once it reaches the stomach, it is typically deactivated by the acidic environment (HCl). If HCl is absent, Tylenol will remain active for a longer period in the stomach.

5. **Analyzing Renin:**
- Renin is an enzyme found in infants that helps in the digestion of milk. It also requires an acidic environment to function effectively. Like Pepsin, it would not work if HCl is not produced.

6. **Analyzing Trypsin:**
- Trypsin is produced in the pancreas and acts in the small intestine. It is not directly affected by the absence of HCl in the stomach since it functions in a different part of the digestive system.

7. **Conclusion:**
- Since HCl is not produced in the stomach, the enzyme that will work for a longer period than usual is **Tylenol (Amylase)**, as it will not be deactivated in the absence of HCl.

### Final Answer:
**Tylenol (Amylase)** will work for a longer period than its usual time if the stomach does not produce HCl.
