Question

Chylomicrons formation occurs in
i) Lumen of small intestine
ii)Mucosal epithelial cells of small intestine
iii)Sub mucosal epithelial cells of duodenum iv)Lacteal of small intestine​

Answer 1

Answer:

ii)Mucosal epithelial cells of small intestine

Explanation:

Formed in the intestinal epithelium to transport long-chain triglycerides to the tissues

(i) Chylomicrons are produced in the epithelial cells of the small intestine.

(ii) It contains triglycerides, cholesterol, and phospholipids.

(iii) They are protein-coated small vesicles.

(iv) Chylomicrons are released from the epithelial cell into lacteals.

Chylomicrons are formed in the endoplasmic reticulum in the absorptive cells (enterocytes) of the small intestine. Newly formed chylomicrons are secreted through the basolateral membrane into the lacteals, where they join lymph to become

Answer 2

Chylomicrons formation occurs in

ii)Mucosal epithelial cells of small intestine

• Small intestine is the last site of gastrointestinal tract where digestion and absorption of food occurs.
• The chylomicrons help in transport of lipids namely triglycerides, cholesterol and phospholipids.
• Chylomicrons enter lymphatic vessels first followed by movement to blood.
• In blood, these chylomicron are converted into chylomicron remnants which are uptaken by liver.
