Anabolismo e catabolismo são processos celulares antagônicos, que são controlados principalmente pela ação hormonal. Por exemplo, no fígado a insulina atua como um hormônio com ação anabólica, enquanto o glucagon tem ação catabólica e ambos são secretados em resposta ao nível de glicose sanguínea.

Em caso de um indivíduo com hipoglicemia, o hormônio citado que atua no catabolismo induzirá o organismo a:
