#Unit 1. Molecules and their Interaction Relevant to Biology

  1. A protein kinase-catalyzed phosphorylation converts trypsinogen to trypsin.

  2. An increase in Ca2+ concentration promotes the conversion.

  3. Proteolysis of trypsinogen forms trypsin.

  4. Trypsinogen dimers bind an allosteric modulator, cAMP, causing dissociation into active trypsin monomers.
