Find out the correct sequence of substrate, enzyme and product Pepsin

Options

A. Small intestine : Proteins - `overset("Pepsin ")to` Amino acids
B. Stomach : Fats -`overset("Lipase")to` Micelles
C. Duodenum: Triglycerides -`overset("Trypsin")to` Monoglycerides
D. Small intestine : Starch `overset(alpha-"Amylase ")to `Maltose

Answer

To find the correct sequence of substrate, enzyme, and product for Pepsin, we need to analyze the role of Pepsin in the digestive process.

### Step-by-Step Solution:

1. **Identify the Enzyme**: Pepsin is a digestive enzyme that is primarily active in the stomach. It is responsible for breaking down proteins into smaller peptides.

2. **Identify the Substrate**: The substrate for Pepsin is proteins. When food enters the stomach, it contains proteins that need to be digested.

3. **Identify the Product**: The product of the action of Pepsin on proteins is smaller peptides. Pepsin cleaves the peptide bonds in proteins, resulting in the formation of these smaller chains.

4. **Sequence the Components**:
- Substrate: Proteins
- Enzyme: Pepsin
- Product: Smaller peptides

Thus, the correct sequence is:
- **Substrate**: Proteins
- **Enzyme**: Pepsin
- **Product**: Smaller peptides
