Question

Atoms can break bonds in food to release energy. calcium atoms form crystals that make bones and teeth strong. oxygen atoms are used in molecules that move energy to different parts of cells.

Answer 1

Atoms can break bonds in food to release energy, which is stored in the chemical bonds of organic molecules. Calcium atoms form crystals that strengthen bones and teeth, and oxygen atoms are used in energy-transporting molecules within cells.

Step-by-step explanation:

Atoms can break bonds in food to release energy. When cells break the bonds in food molecules, energy is released and used to build new compounds. This energy is stored in the chemical bonds of organic molecules, which are a reservoir of potential energy called chemical energy. Calcium atoms form crystals that make bones and teeth strong, while oxygen atoms are used in molecules that transport energy within cells.
