Understand that nutrients are molecules that organisms use to obtain energy and build cellular structures.
Recognize that energy in biological systems is stored in the form of chemical energy.
Chemical energy is primarily stored in the chemical bonds between atoms in a molecule.
When these chemical bonds are broken during metabolic processes, energy is released and can be used by the organism.
Therefore, the primary storage of energy in nutrients is in the chemical bonds of molecules.
