Which enzymes are likely to act on the baked potatoes eaten by a man, starting from the mouth and as it moves down the alimentary canal?
Options
- APancreatic amylase Salivary amylase Lipases
- BDisaccharidase like maltase Lipases Nucleases
- CSalivary amylase Pancreatic amylase Disaccharidase
- DSalivary maltase Carboxy peptidase Trypsinogen
Correct answer
C. Salivary amylase Pancreatic amylase Disaccharidase
Step-by-step solution
Baked potatoes consists of starch, which is a polysaccharide. Hence, it is acted upon by salivary amylase in mouth which converts starch into maltose, isomaltose and dextrin Starch amylase Salivary Maltose + Isomaltose + -Dextrins. Similarly, in small intestine, pancreatic amylase acts on starch to produce disaccharides maltose, isomaltose and dextrin. Starch -anylase Pancreatic Maltose + Isomaltose + -Dextrins Then, these disacchararides are acted upon my intestinal juicesmaltase and convert it into monosaccharide
