Pepsin enzyme hydrolyses

Options

A. proteins to amino acids
B. fats to fatty acids.
C. glucose to ethyl alcohol.
D. polysaccharides to monosaccharides

Answer

### Step-by-Step Text Solution:

1. **Understanding Pepsin**: Pepsin is an enzyme that plays a crucial role in the digestive system, specifically in the stomach. It is responsible for breaking down proteins.

2. **Function of Pepsin**: The primary function of pepsin is to hydrolyze proteins into smaller peptides and eventually into amino acids. Proteins are made up of long chains of amino acids, and pepsin facilitates the breakdown of these chains.

3. **Optimal Conditions for Pepsin**: Pepsin operates best in highly acidic conditions, with an optimal pH range of 1 to 2. This acidic environment is typically found in the stomach.

4. **Effect of pH on Pepsin Activity**: If the pH level rises above 2, pepsin becomes inactive. For instance, at a pH of 3, pepsin does not function effectively.

5. **Summary of Pepsin's Role**: In summary, pepsin hydrolyzes proteins into amino acids, which are essential for various metabolic processes in the body.

### Final Answer:
Pepsin enzyme hydrolyzes proteins into amino acids.
