Small intestine
Which process refers to all the chemical changes that change food to energy in the body?
Metabolism
What is the role of bile in the process of digestion?
Bile helps in the breakdown of complex molecules into simpler molecules
How does osmosis contribute to the process of absorption in the small intestine?
Osmosis allows the movement of simple molecules across the cell membranes

Study Notes
Digestion and Absorption
- The process of breaking down complex molecules into simpler molecules is digestion.
Absorption of Nutrients
- The simple molecules resulting from digestion pass through cell membranes into the blood or lymph capillaries in the walls of the small intestine.
Metabolic Process
- The process that refers to all the chemical changes that change food to energy in the body is metabolism.
Role of Bile
- Bile, produced by the liver and stored in the gallbladder, plays a role in the process of digestion by breaking down fats into smaller components.
Absorption in the Small Intestine
- Osmosis, the movement of water molecules from an area of high concentration to an area of low concentration, contributes to the process of absorption in the small intestine by facilitating the movement of nutrients into the bloodstream.
Components of Metabolism
- Metabolism encompasses all the chemical changes that convert food into energy, including anabolic reactions that build molecules, and catabolic reactions that break down molecules.
Test your knowledge about the processes of digestion, absorption, and metabolism. This quiz covers the breaking down of complex molecules, absorption of simple molecules into the bloodstream, and the overall metabolic processes in the body.
