|
produces HCl to kill germs
|
|
|
HCl activates pepsinogen to pepsin
|
|
|
activates the enzyme renin to coagulate milk casein
|
|
|
produce trypsinogen which is activated by enterokinase
|
|
|
pepsin breaks down proteins into proteoses and peptones
|
Explanation:
Detailed explanation-1: -Trypsinogen is activated by enterokinase, which cleaves an amino-terminal activation peptide (TAP). Active trypsin then cleaves and activates all of the other pancreatic proteases, a phospholipase, and colipase, which is necessary for the physiological action of pancreatic triglyceride lipase.
Detailed explanation-2: -The glands of “Bruner” which forms the lining of duodenum secretes a proteolytic enzyme called enteropeptidase which converts the inactive trypsinogen secreted by the pancreatic cells to active trypsin. Therefore, enterokinase stimulates inactive trypsinogen. So, option D is the correct answer.
