As células beta producen, almacenan e liberan [[insulina]], unha [[hormona]] que controla o nivel de glicosa no sangue cando este aumenta. O fígado mantén o nivel basal de glicosa, e as células beta do páncreas poden responder rapidamente aos picos que se produzan na concentración de glicosa sanguínea, liberando parte da insulina que almacenan e producindo á vez máis insulina. O tempo de resposta é moi rápido.
Beta cells store and release [[insulin]], a [[hormone]] that controls the level of glucose in the blood. The liver maintains the base-line glucose level, but the beta cells can respond quickly to spikes in blood glucose by releasing some of its stored insulin while simultaneously producing more. The response time is very quick.
