Enterokinase A. is a hormone. B. triggers the release of bile from the gallbladder. C. activates trypsinogen. D. increases duodenal motility. E. digests proteins.

Option C.

Activate trypsinogen.

Explanation:

Enterokinase is an enzyme produced by the dudoneum that specifically cleaves the acidic propeptide from trypsinogen and then activating it to produce active trypsin. It activate the trypsinogen because it need to produce trypsin which inturn activate other enzymes and initiates a cascade of proteolytic reactions that lead to the activation of many pancreatic zymogens which is important for the physiological action of pancreatic triglyceride lipase

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.
