Which organ of digestive system secretes the enzyme lipase for digesting emulsified fats in humans?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3: Pancreas.
Explanation:
In the digestive system, the pancreas is the organ responsible for secreting 'pancreatic juice.' This juice contains an enzyme called lipase, which functions to digest emulsified fats by breaking them down into fatty acids and glycerol. The emulsification of fats is initially carried out by bile juice secreted by the liver, after which lipase is able to act upon them effectively.
Additional Facts:
- Other Pancreatic Enzymes: In addition to lipase, the pancreas also secretes trypsin (for proteins) and amylase (for carbohydrates).
- Liver: This is the largest gland in the body; it produces bile juice (though the bile itself contains no enzymes).
- Gallbladder: This organ functions to store and concentrate the bile juice produced by the liver.
- Small Intestine: This is where the complete digestion and absorption of food take place. Its walls also secrete 'intestinal juice,' which contains enzymes capable of digesting fats.
