Assertion (A): In human body, liver has important role in fat digestion. Reason (R): Liver produces two important fat-digesting enzymes.

aBoth A and R are individually true and R is the correct explanation of A
bBoth A and Rare individually true but R is not the correct explanation of A
cA is true but R is false
dA is false but R is true
✓ Correct answer: c) A is true but R is false
ExplanationAssertion (A) is true: The liver plays a crucial role in the digestion of fats.The liver’s primary role is to produce bile, which is essential for the digestion and absorption of fats.Science and Technology 621 Bile is stored in the gallbladder and released into the small intestine when fat is detected in the stomach.Bile emulsifies fats by breaking them down into smaller droplets.This makes it easier for digestive enzymes, primarily lipase from the pancreas, to act on the fats and break them down further.Reason (R) is false: The liver does not produce fat-digesting enzymes.The production of fat-digesting enzymes occurs in the pancreas, not the liver.Lipase enzyme is secreted by the pancreas and is responsible for breaking down triglycerides (fats) into glycerol and fatty acids.Lipase works on the small fat droplets that have been emulsified by bile.418
