fatty acids and monoglycerides
|
|
|
fatty acids and triglycerides
|
|
|
fatty acids only
|
|
|
glycerides only

Explanation:
Detailed explanation-1: -The micelles are water soluble and enable the lipid digestion products to be transported to the small intestinal surface for absorption. At the site of absorption, the micelle breaks down and the bile salt returns to the intestine for continuing emulsification processes (bile salt recycling).
Detailed explanation-2: -Lipids enter the smooth endoplasmic reticulum Emulsification Lipase digests fat droplet CCK is secreted Gallbladder releases bile Chylomicrons are taken up by the lymphatic system Micelles are formed v, ii, iv, iii, vii, vi, Which is the correct order of events for lipid absorption?
