Sin embargo, muchas de esas moléculas son esenciales para la célula. Pensemos, por ejemplo, en la glucosa o en los iones que crean gradientes electroquímicos. Como dijimos en apartados anteriores la creación de gradientes entre ambos lados de la membrana es necesaria puesto que se usan en muchos aspectos de la fisiología celular. Pero para que estos gradientes sean útiles es necesario que la célula pueda crearlos, regularlos y romperlos cuando lo necesite. En la membrana existen unas proteínas especializadas tanto en el transporte de moléculas necesarias para el metabolismo como en la creación y modificación de los gradientes electroquímicos. Son proteínas transmembrana que se agrupan en tres tipos: bombas, transportadores y canales"]]]],["element",{"elementId":"38"},["name","Coverage"],["description","The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant"],["elementTextContainer",["elementText",{"elementTextId":"11209"},["text","2015-01-01"]]]],["element",{"elementId":"45"},["name","Publisher"],["description","An entity responsible for making the resource available"],["elementTextContainer",["elementText",{"elementTextId":"11210"},["text","Atlas de Histología Animal y Vegetal "]]]]]]],["tagContainer",["tag",{"tagId":"4103"},["name","membrana"]],["tag",{"tagId":"4153"},["name","transporte de proteínas."]]]]
