Question

Read the following reactions and choose the correct option. HCI 1. Pepsinogen ----→ Pepsin Pepsinogen 2. Proteins ----------→ Proteoses + peptones HCI 3. Trypsinogen ----→ Trypsin Enterokinase 4. Chymotrypsinogen -------------→ Chymotrypsin Trypsin 5. Peptones -------→ Dipeptides

Answer 1

Answer:

3 and 4 are the correct options

Explanation:

1) the reaction is catalysed by HCl and not pepsinogen

2) Pepsin is responsible for this conversion

3) Enterokinase catalyses conversion of trypsinogen to active enzyme trypsin

4) trypsin can catalye conversion of chymotrypsinogen to chymotrypsin

5) Peptones are broken down to dipeptides by the action of enzyme dipeptidases
