Solution

The correct option is B Salivary amylase, pancreatic amylase, disaccharidases
Baked potatoes consist of starch which is a polysaccharide. In oral cavity, the food is mixed with saliva. The saliva contains an enzyme called salivary amylase (also called ptyalin) which converts starch into maltose, isomaltose and small dextrins. Salivary amylase is activated in the saliva by the chloride ions. The pancreatic juice (present in small intestine) contains starch digesting enzyme, called pancreatic amylase which converts starch into maltose, isomaltose and α-dextrins.
Hence, the correct answer is option B.

Q. Common feature shared by salivary amylase, pancreatic lipase and pepsin is that they are all

Amylase is a digestive enzyme that acts on starch in food, breaking it down into smaller carbohydrate molecules. Once food along with salivary amylase enters the stomach, action of hydrolytic enzymes lead to amylase deactivation. In case, the undigested starch still remains, how will it be digested?
