I think it's oxygen and water because they are the substance for cellular respiration.
Breaking chemical bonds is typically an endothermic process, which means energy must be added (it must pull in energy)
Breaking of chemical bonds is always endothermic meaning it wants energy, so it takes energy from its surroundings and sucks it in. Think of 'endo' as inside. The chemical bonds want energy inside of it so it can break.
Forming of chemical bonds is exothermic, meaning it releases energy into its surroundings. Think of 'exo' as outside, or exterior, it releases its energy outside of itself.
I hope that makes some kind of sense :)
The same ligand can bind to different receptors causing different responses (e.g.. acetylcholine). On the other hand, different ligands binding to different receptors can produce the same cellular response (e.g. glucagon, epinephrine).
