A secretion that digests both carbohydrates and proteins is -

Options

A. ptyalin
B. pepsin
C. pancreatic juice
D. saliva

Answer

To solve the question "A secretion that digests both carbohydrates and proteins is -", we can follow these steps:

### Step 1: Understand the question
The question asks for a secretion that has the ability to digest both carbohydrates and proteins.

### Step 2: Identify the options
The options provided are:
1. Al and Pepsin
2. Pancreatic juice
3. Saliva

### Step 3: Analyze each option
- **Al and Pepsin**: Pepsin is an enzyme that digests proteins but does not digest carbohydrates. Therefore, this option is not correct.

- **Pancreatic juice**: This secretion contains several enzymes, including amylase (which digests carbohydrates), trypsin (which digests proteins), and lipase (which digests fats). Since pancreatic juice digests both carbohydrates and proteins, this option is likely correct.

- **Saliva**: Saliva contains the enzyme amylase, which helps in the digestion of carbohydrates (specifically starch), but it does not digest proteins. Therefore, this option is not correct.

### Step 4: Conclusion
Based on the analysis, the secretion that digests both carbohydrates and proteins is **pancreatic juice**.

### Final Answer
The correct answer is **pancreatic juice**.
