Question

Glycerol and _____ diffuse easily into intestinal cells, which release them into capillaries without further processing.

Answer 1

Answer:

Glycerol and fatty acid diffuse easily into the intestinal cells, which release them into capillaries without further processing.

Explanation:

The glycerol and fatty acids are simpler forms of fats. During digestion, the fats are digested in the form of fatty acids and glycerol. The fat digestion occurs in the duodenum and jejunum of the small intestine.

The bile juice from the liver and pancreatic juice from the pancreas helps in the digestion of fats. The bile juice mixes with the larger fat molecules in the small intestine and breaks it down into smaller parts. These smaller fat molecules are known as emulsified fats.

Then by the action of gastric juice, it further simplified. The gastric juice contains a fat-digesting enzyme - gastric lipase. By the action of gastric lipase, the smaller fat molecule chains are broken down. Thus the fats convert into fatty acids and glycerol. This happens in the stomach. But not all the fat molecules are simplified.

In the intestine after the action of bile, pancreatic lipase from the pancreas again acts on emulsified fats. Thus the fats are digested into fatty acids and glycerols. These are the end product of fats.

Then these digested fats are ready for absorption. The absorption occurs by the process of simple diffusion. Thus fatty acids and glycerols reach the blood vessels.
