NEET Biology question
Not in NEET syllabus
Go through the following statements regarding the absorption of fats. Find correct and incorrect statements and choose an option accordingly from the codes given below. I. Micelles and chylomicron are concerned with the absorption of fats II. Chylomicrons are water soluble dropelets of fat which contains triglycerides, sterol and phospholipids III. Micelles are water soluble droplets of fatty acids and glycerols which are formed by the action of bile pigments on fats and glycerol IV. Chylomicron, protein coated small vesicles are released from the intestinal cells into the blood stream by lacteals
Solution
Absorption of fats and fat soluble vitamins takes place by simple diffusion. Fats and fats soluble vitamins like A, D, E, K cannot reach into the blood directly, due to insolubility in water. So, they are first incorporated into small, spherical water soluble droplets called micelles by the action of bile salts
