Solution
The correct option is D Small intestine The pancreatic juice (trypsinogen, chymotrypsinogen, procarboxypeptidase, amylases, lipases and nucleases) and intestinal juice (disaccharidases, dipeptidases, lipases, enterokinase, nucleotidases and nucleosidases) present in the small intestine help in the digestion of biomacromolecules. The inactive trypsinogen is activated by an enzyme enterokinase to form trypsin, which in turn activates the other enzymes in the pancreatic juice. These activated pancreatic enzymes partially digest the carbohydrates, lipids, proteins and nucleic acids, and thereafter, the intestinal juices complete the next stage of digestion in the small intestine. Hence, the breakdown of biomacromolecules such as carbohydrates, fats and proteins mostly occurs in the small intestine.
The given table gives a detailed progress of the digestion in the human body:
