How is trypsinogen converted to trypsin? A) A protein kinase-catalyzed phosphorylation converts trypsinogen to trypsin. B) An increase in Ca²⁺ concentration promotes the conversion. C) Proteolysis of trypsinogen forms trypsin. D) Trypsinogen dimers bind an allosteric modulator, cAMP, causing dissociation into active trypsin monomers. E) Two inactive trypsinogen dimers pair to form an active trypsin tetramer.

Question

Quizplus · Accepted Answer

Trypsinogen is converted to trypsin through proteolysis, which involves the cleavage of a peptide bond within trypsinogen. This cleavage exposes the active site of the enzyme, allowing it to function as a protease. This conversion can be catalyzed by a variety of enzymes, including trypsin itself, as well as other proteases such as enteropeptidase in the small intestine.
