Select the correct statement .

Options

A. Trypsinogen `overset("Chymotrypsin")(rarr)` Trypsin
B. Procarboxy peptidase `overset("Pepsin")(rarr)` Carboxypeptidase
C. Proamylase `overset("Ptylin")(rarr)` Amylase
D. Pepsinogen `overset("HCl")(rarr0` Pepsin

Answer

To solve the question of selecting the correct statement regarding the conversion of various digestive enzymes, we will analyze each statement provided:

1. **Statement 1**: "Trypsinogen is converted into trypsin via enzyme chymotrypsin."
- **Analysis**: This statement is incorrect. Trypsinogen is actually converted into trypsin by the enzyme enterokinase, not chymotrypsin.

2. **Statement 2**: "Procarboxypeptidase is converted to carboxypeptidase via enzyme pepsin."
- **Analysis**: This statement is also incorrect. Procarboxypeptidase is converted to carboxypeptidase by the enzyme trypsin, not pepsin.

3. **Statement 3**: "Proamylase is converted into amylase via enzyme ptyalin."
- **Analysis**: This statement is incorrect as well. Proamylase is converted into amylase by the action of hydrolases, not ptyalin.

4. **Statement 4**: "Pepsinogen is converted to pepsin via enzyme HCl."
- **Analysis**: This statement is correct. Pepsinogen is indeed converted into pepsin in the presence of hydrochloric acid (HCl).

Based on the analysis above, the correct statement is:

**Correct Answer**: Pepsinogen is converted to pepsin via enzyme HCl.
