    1. ANSWR: (b) Eggs contain fats. Bile juice from the liver breaks down large fat globules into smaller ones for increasing the efficiency of the enzymes and making the medium alkaline. Emulsified fats are digested by lipase secreted by pancreas.

      ANSWER: (c) Sweet potatoes are rich in starch. The saliva secreted by salivary glands present in buccal cavity contain an enzyme called salivary amylase that breaks down starch which is a complex molecule to give sugar.

      ANSWER: (d) Small Intestine will have a maximum amount of digested food as the process of digestion is completed in the small intestine.
