Why would organisms break the bonds of organic compounds?

• in order to use the smaller molecules to plug the gaps in the cell membrane to slow diffusion

• to use the energy obtained to digest molecules produced by respiration that uses oxygen

• for energy or to reassemble the resulting materials to form different compounds
