Sveta_85 [38]2 years ago

Las paredes externas de una casa o un automóvil brindan una barrera fuerte e inflexible que protege a sus habitantes humanos de un mundo externo rudo e impredecible. Podría esperarse que el límite externo de una célula viva estuviera construido de una barrera igual de fuerte e impenetrable porque también debe proteger su delicado contenido interno ante un ambiente no vivo y a menudo inhospitalario. Sin embargo, las células están separadas del mundo externo por una estructura delgada y frágil llamada membrana plasmática que sólo mide 5 a 10 nm de espesor. Se requerirían casi 5 000 membranas plasmáticas apiladas una sobre otra para igualar el grosor de una sola página de este libro.

This concept differs from pesticides because these are substances used to control pests and from bio remediators because these are used to deal with contamination. Therefore, the word that describes synthetic compounds that are not produced or expected to be present in an organism is xenobiotics.
