Which pancreatic enzyme begins the digestion of proteins in the small intestine after activation by enterokinase?
Correct answer: A. Trypsin
- A. Trypsin
- B. Pancreatic amylase
- C. Pancreatic lipase
- D. Nuclease
Explanation
Enterokinase, also called enteropeptidase, activates trypsinogen to trypsin in the duodenum. Trypsin then activates other pancreatic proteases, while amylase digests starch and lipase digests fats.

About Digestive System
The digestive system covers the structure and functions of the alimentary canal from mouth to anus, along with the liver, gallbladder and pancreas. It explains mechanical and chemical digestion, the action of major enzymes, absorption through intestinal villi, and how digestion differs from absorption and assimilation.
