Question

As liver hepatocytes make bile, they secrete it into collecting structures called:

What molecule are bile salts (aka bile acids) made from?

What is the intestinal brush border enzyme that converts trypsinogen into trypsin? (answer is not enteropeptidase)

Answer 1

Answer

1) As liver hepatocytes make bile, they secrete it into collecting structures called : Bile canaliculi

• Bile performs emulsification of fat entering in the duodenum.
• Bile is stored in gallbladder.

2) The molecule from which are bile salts (aka bile acids) made from is : Cholesterol

3) The intestinal brush border enzyme that converts trypsinogen into trypsin is : Enterokinase

• Brush border of mucosal lining in the itestinal wall secretes enterokinase. Enterokinase converts inactive trypsinogen secreted by pancreas into its active form called trypsin.
