Select the correct sequential steps regarding absorption of fatty acids and glycerol, in intestine. (A) Micelles are reformed into small protein coated fat globules called chylomicrons. (B) Micelles move into intestinal mucosa. (C) Fatty acids and glycerol are incorporated into small droplets called micelles. (D) Lacteals release the absorbed substances into blood stream. (E) Chylomicrons are transported into lacteals.

A (A), (E), (B), (D), (C)
B (D), (E), (B), (C), (A)
C (C), (B), (A), (E), (D)
D (B), (C), (E), (A), (D)

The answer is C.

Solution

Correct sequence: Fatty acids and glycerol are incorporated into small droplets called micelles (C) → Micelles move into the intestinal mucosa (B) → Within the mucosal cells, micelles are reformed into small protein-coated fat globules called chylomicrons (A) → Chylomicrons are transported into the lacteals (E) → Lacteals release the absorbed substances into the bloodstream (D). Order: C, B, A, E, D.
