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

The Assertion is true: the liver plays an important role in fat digestion by secreting bile, which neutralises stomach acid and emulsifies fats into tiny droplets, facilitating their digestion and absorption [1]. The Reason is false: the liver primarily produces bile (containing bile salts) rather than hydrolytic fat‑digesting enzymes. The key luminal enzyme that hydrolyses triglycerides is pancreatic lipase, secreted by the pancreas into the small intestine; intestinal enzymes further complete fat breakdown [3]. Bile salts work cooperatively with pancreatic lipase and colipase to enable efficient lipid hydrolysis and micelle formation for absorption, rather than acting as digestive enzymes themselves [4]. Thus A is true but R is false.
