Answer #1

Chemical digestion : the breakdown of foods into smallmolecules by enzymes present in the secretions released from the glands and other organs of digestive system.

Fats are the macromolecules that are made of fatty acids and gylcerol(triglycerides).

MOUTH : in mouth there are no enzymes to break fats

STOMACH : no breakdown of fats occurs

SMALL INTESTINE : small intestine is the major effective site for chemical digestion of fats because the PANCREATIC lipase released from pancreas and bile salts from Liver are present.

These pancreatic lipase breaks the fats into fatty acids and glycerol.

Bile salts emulsifies the fats.

The pancreatic juice release is stimulated by passage of gastric contents from the stomach to duodenum and by the secretion of secretin, cholecystokinin.

Hence , chemical digestion occurs in the small intestine and the answer is C
