Metabolism and Energy Production Quiz

The role of energy in living organisms is to perform virtually every task, including heavy labor, exercise, thinking, and cellular processes such as metabolism, synthesis, and breakdown of molecules.

Living cells constantly use energy for importing nutrients and molecules, metabolizing and synthesizing molecules, modifying molecules if needed, transporting molecules within the cell, and distributing molecules to the entire organism.

Energy is used to build large proteins from smaller molecules, such as the muscles actively built from smaller protein molecules. It is also used to break down complex carbohydrates into simple sugars that the cell uses for energy.
