Question

which accessory organ of the gi system secretes enzymes that break down fats and carbohydrates?
pancreas
liver
salivary gland
jejunum

Explanation:

The pancreas is an accessory GI organ that secretes pancreatic lipase (breaks down fats) and pancreatic amylase (breaks down carbohydrates). The liver produces bile (emulsifies fats but does not secrete digestive enzymes for fats/carbs), salivary glands secrete salivary amylase (only breaks down carbohydrates, no fat-digesting enzymes), and the jejunum is a primary GI tract organ, not an accessory organ.

Answer:

Pancreas
