Solution

The correct option is D Lipase, amylase, trypsinogen, procarboyxpeptidase
The digestive glands associated with the alimentary canal secrete several enzymes that help in chemical digestion of food.

Gastric juice secreted by the gastric glands in the stomach contains enzymes such as pepsinogen and rennin (proteases).

The exocrine pancreas secretes pancreatic juice that contains enzymes like trypsinogen, chymotrypsinogen, procarboxypeptidase, amylases, lipases and nucleases.

Trypsinogen, chymotrypsinogen and procarboxypeptidase are involved in protein digestion. Amylase is involved in digestion of carbohydrates. Lipase is involved in lipid digestion. Nucleases break down the nucleic acids (DNA/RNA).

The intestinal juice or succus entericus contains a variety of enzymes like disaccharidases (e.g., maltase, sucrase and lactase), dipeptidases, lipases, nucleosidases.
