Question

g Select the processes that make lipids accessible for the digestion. The low pH of the stomach breaks down fatty acids. Micelles carry fatty acids to the intestinal membrane. Lipases degrade triacylglycerols into fatty acids. Lipid droplets and water mix into an emulsion in the stomach.

Answer 1

The processes that make lipids accessible for digestion include emulsification by bile, lipase activity in degrading triglycerides, and micelle formation with the help of bile salts.

Step-by-step explanation:

The processes that make lipids accessible for digestion include:

1. Emulsification: Bile, produced in the liver and stored in the gallbladder, aids in the digestion of lipids by emulsifying large lipid globules into smaller ones. Bile salts, which are amphipathic, help break down the lipid molecules and suspend them in the digestive medium.
2. Lipase activity: Lipases, such as lingual lipase, gastric lipase, and pancreatic lipase, degrade triglycerides into fatty acids. Pancreatic lipase plays a significant role in lipid digestion in the small intestine.
3. Micelle formation: Bile salts attach to triglycerides, helping them form micelles. Micelles are small particles that can disperse through the watery contents of the duodenum, increasing the accessibility of the lipid molecules to lipase.

Answer 2

Lipases liberate the triglycerides into fatty acids is the process which makes lipids accessible for the digestion.

Step-by-step explanation:

The triglyceride and other lipids of small intestine are delivered to in the bile for digestion. The molecules of triglyceride get digest ready by enzymes to degrade fatty acids and monoglyceride to transport it to the enterocyte. The process is executed by the lipase and bile acids.

The water soluble enzyme lipase initiates the emulsification process of lipids. It works on the droplets of the surface of triglyeride and liberates the fatty acids along with the monoglyceride retaining its connection with bile acids and other lipids to create micelles structures.
