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

  1. APancreatic amylase Salivary amylase Lipases
  2. BDisaccharidase like maltase Lipases Nucleases
  3. CSalivary amylase Pancreatic amylase Disaccharidase
  4. 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
