Describe the digestive role of chymotrypsin. What two other digestive enzymes of the same category are secreted by its source gland? |
|
Answer» The enzyme trypsin (present in the pancreatic juice) activates the inactive enzyme chymotrypsinogen into chymotrypsin. `underset("(Inactive)")"Chymotrypsinogen" overset("Trypsin")rarr underset("(Active)")"Chymotrypsin"` The activated chymotrypsin plays an important role in the further breakdown of the partially-hydrolysed proteins. `"Proteins "overset("Chymotrypsin")rarr "Peptides "` The other digestive enzymes of the same category are trypsinogen and carboxypeptidase. These are secreted by the same source-gland, pancreas. Trypsinogen is present in an inactive form in the pancreatic juice. The enzyme enterokinase – secreted by the intestinal mucosa – activates trypsinogen into trypsin. `"Trypsinogen " overset("Enterokinase")rarr" Trypsin + Inactive peptide"` The activated trypsin then further hydrolyses the remaining trypsinogen and activates other pancreatic enzymes such as chymotrypsinogen and carboxypeptidase. Trypsin also helps in breaking down proteins into peptides. `"Proteins "overset("Trypsin")rarr" Peptides"` Carboxypeptidases act on the carboxyl end of the peptide chain and help in releasing the last amino acids. `"Peptides "overset("Carboxypeptidase")rarr" Small peptide chain + Amino acids"` |
|

(i) As a digestive gland, liver secretes what? Where is this secretion stored? Name the enzymes secreted by liver. (ii) Digestive secretion of liver contains which salts? What is their function? |
|
Answer» (i) Liver secretes bile. It is stored in gall bladder. Bile secretions contain no enzymes. (ii) Bile contains salts, namely sodium glycocholate and sodium taurocholate. These reduce the surface tension of large fat droplets break them into many small ones. The process is called emulsification. Bile salts also form a thin coating around tiny fat droplets to keep them away from coalescing. |
