1. which of the following produces trypsinogen?

a. liver
b. pancreas
c. stomach
d. small intestine

1. which cell produces hcl?

a. parietal
b. chief
c. acinar
d. hepatocyte

1. what is the function of bile?

a. physical breakdown of protein
b. chemical breakdown of protein
c. physical breakdown of lipids
d. chemical breakdown of lipids

Explanation:

1. Trypsinogen is an enzyme precursor produced by the pancreas. The pancreas secretes it into the small intestine where it is activated to trypsin.
2. Parietal cells in the stomach lining produce hydrochloric acid (HCl). Chief cells produce pepsinogen, acinar cells are related to exocrine pancreatic function (producing digestive enzymes like pancreatic amylase, lipase etc.), and hepatocytes are liver cells.
3. Bile is produced by the liver and stored in the gall - bladder. It emulsifies (physically breaks down) lipids. Lipase is the enzyme that chemically breaks down lipids.

Answer:

1. b. Pancreas
2. a. Parietal
3. c. Physical breakdown of lipids
