Does the small intestine break up molecules?

Enzymes in the small intestine can break larger molecules such as proteins into smaller molecules such as amino acids. These enzymes are either produced in the pancreas and taken to the first part of the small intestine by the pancreatic duct or some enzymes may be produced by the lining of the small intestine called the "brush border" in the first part of the small intestine. Large molecules such as proteins or starch need to be broken down to smaller molecules before they can be absorbed into the bloodstream and beusableto the person's body cells.

Small intestine


Nutrient molecules pass from the small intestine into the bloodstream through tiny structures called what?

Nutrient molecules pass from the small intestine into the through tiny structures called villi.


Where are food molecules absorbed into the bloodstream?

Food molecules are primarily absorbed into the bloodstream in the small intestine. The inner lining of the small intestine is covered in finger-like projections called villi, which increase the surface area available for absorption. Nutrients from food pass through the walls of the small intestine and into the bloodstream, where they are transported to cells throughout the body.

What happens to small molecules of protein in the mouth?

In the mouth, small molecules of protein are broken down by enzymes called proteases. These enzymes break down the protein molecules into smaller peptides and amino acids, which can then be absorbed through the lining of the small intestine for use by the body.


What is the process of molecules breaking down in the intestine?

In the intestine, complex molecules are broken down into simpler molecules by enzymes released from the pancreas and small intestine. These simpler molecules, such as sugars, amino acids, and fatty acids, can then be absorbed into the bloodstream through the intestinal lining for use by the body. The process of breaking down molecules in the intestine is crucial for extracting nutrients from food.
