This may eventually have led to mechanisms that facilitate movement of molecules to the inside of the protocell (endocytosis) or to release its contents into the extracellular space (exocytosis).
Isto puido finalmente orixinar mecanismos que facilitan o movemento de moléculas no interior da protocélula (endocitose) ou para liberar o seu contido no espazo extracelular (exocitose).
