Answer 1

Answer: (C)

Trypsin is a digestive enzyme produced by acinar cells of the pancreas, and it hydrolyzes the proteoses and peptones in peptides.
Insulin is a peptide hormone produced by the beta cells of Islets of Langerhans and controls the blood sugar level.
Morphine, an alkaloid, is an opiate narcotic and is derived from opium. Morphine is a most valuable analgesic but it causes addiction. Morphine has sleep and dream-inducing properties.
