DIGESTION IN HUMANS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ in the pancreatic and intestinal juice completes the digestion of fats.
A
Amylase
B
Protease
C
Lipase
Explanation: 

Detailed explanation-1: -Pancreatic juice secreted by the pancreas contains a variety of enzymes, such as trypsinogen, chymotrypsinogen, pancreatic lipase, amylase etc. Trypsin and chymotrypsin help digest proteins; amylase help in digestion of carbohydrates; and lipase to break down fats.

Detailed explanation-2: -The bile mixes with the fat in food. The bile acids dissolve fat into the watery contents of the intestine, much like how detergents dissolve grease from a frying pan, so the intestinal and pancreatic enzymes can digest the fat molecules.

Detailed explanation-3: -Lipase. This enzyme works together with bile, which your liver produces, to break down fat in your diet. If you don’t have enough lipase, your body will have trouble absorbing fat and the important fat-soluble vitamins (A, D, E, K). Symptoms of poor fat absorption include diarrhea and fatty bowel movements.

Detailed explanation-4: -Pancreatic juice is a liquid secreted by the pancreas that contains a variety of enzymes, including trypsinogen, chymotrypsinogen, elastase, carboxypeptidase, pancreatic lipase, nucleases, and amylase.
