Question

which accessory organ of the gl system secretes enzymes that break down fats and carbohydrates?
pancreas

Explanation:

The pancreas is an accessory organ of the GI (gastro - intestinal) system. It secretes pancreatic lipase to break down fats and pancreatic amylase to break down carbohydrates. The liver mainly produces bile for fat emulsification, salivary glands secrete saliva with amylase mainly for initial carbohydrate breakdown in the mouth, and the jejunum is a part of the small intestine, not an accessory organ secreting such enzymes.

Answer:

A. Pancreas
