Question

Assertion :Liver secretes bile juice that does not contain enzymes but helps in digestion Reason: Bile carries out emulsification of fats and provide alkaline medium for activity of other enzymes

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

• After the food is stored in the stomach it is mixed with the acid that is present in the stomach which is required to decrease the pH of the food so that the enzyme pepsinogen is activated and is used for digestion of proteins in the food.
• From the stomach the food travels to the small intestine where before it enters it is mixed with the secretions from the liver and pancreas.
• The secretion of the liver is the bile which does not contain any digestive enzymes but it is used for the emulsification of fat so that the fat present in the food is broken down to small fat globules which can be digested easily.
• Also the bile has an alkaline nature which is required for the activation of the pancreatic enzymes.
• Also as the bile and the pancreatic juices enter the intestine via hepatopancreatic duct they mix with the acidic chime from the stomach and neutralize its pH.
• And further digestion in the intestine is continued.
• Therefore the answer option A is correct.
