an organic compound consisting of atoms of carbon, hydrogen, and oxygen
the most organizational unit of organisms
the process by which a cell uses the chemical reactivity of oxygen to split glucose into its constituent parts, water and carbon dioxide, and thereby release chemical energy that can be used to form chemical bonds or to perform other tasks within the cell
potential energy held in the bonds between atoms

a molecule whose atoms are
A chemical bond formed by the sharing of one or more electrons, especially pairs of electrons, between atoms.
deoxyribonucleic acid (DNA)
nucleic acids that are usually the molecular basis of heredity, are localized especially in cell nuclei, and are constructed of a double helix held together by hydrogen bonds between purine and pyrimidine bases which project inward from two chains containing alternate links of deoxyribose and phosphate
