Q

Tipos Endocitosis

A
  • Mediado por receptores: (CLATRINA: proteinas que se encuentra en el citoplasma y se adhiere a memebrana para formar vesiculas)
  • Fagocitosis: Particulas de gran tamaño, comer de la celula ATP
  • Pinoctiosis: Incorporacion de un liquido y pequeñas moleculas. Vesiculas pequeñas
