Answer: 2. trypsinogen into trypsin

Enterokinase, secreted by the intestinal mucosa, activates trypsinogen into trypsin. Trypsin then activates other pancreatic zymogens.

Pepsinogen is activated to pepsin by HCl, and the conversion of caseinogen to casein is by rennin. Proteins to polypeptides is done by proteases such as pepsin.
