Item EB069001: Protein, carbohydrate, and fat molecules from food are broken down in the digestive system into smaller molecules (subunits) that can enter the blood stream and be distributed throughout the body.
What happens to the protein, carbohydrate, and fat molecules from food while in the digestive system?
- In the digestive system, they are broken down and reassembled into other protein, complex carbohydrate, and fat molecules that are needed to build body structure.
- In the digestive system, they are broken down into carbon dioxide and water during a chemical reaction that provides the energy needed to survive.
- In the digestive system, they are broken down into smaller molecules (subunits) that can enter the blood stream and be distributed throughout the body.
- Nothing happens to them in the digestive system. They pass through the digestive system unchanged and then enter the blood stream.

- LS1.A In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions.
LS1.A Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level.
