Question

Bile salts bind at their hydrophobic regions to large fat globules within the chyme that enters the duodenum. Bile salts break up the fat globule into smaller fat droplets. This role of bile salts is best described as

a. Lipid emuslification
b. Lipid ingestion
c. Lipid digestion
d. Lipid absorption

Answer 1

Answer: A

Step-by-step explanation:

Emulsification of fats into globules is one of the digestive processes which aid digestion and assimilation of fats. The objective is to breakdown large fat globules into many tinny globules. The bile salts is an emulsifier.Thus it has both the hydrophilic and hydrophobic ends.Therefore by binding to both ends, and mixing vigorously,its easily breaks the large lipid molecule down to tiny fragments for absorption in the lacteal en route the lymphatic vessels,

Answer 2

a. Lipid emuslification

Step-by-step explanation:

Fats are organic compounds whose main function is to provide energy for the body to help transport and absorb fat soluble vitamins and to incorporate essential fatty acids that the body does not produce on its own. Fat digestion begins when the chyme passes from the stomach to the duodenum, where the bile assists in the digestion of fats and other lipids. When the chyme is in the duodenum, a hormone stimulates contraction of the gallbladder walls and releases bile through the common bile duct.
