This is the FedEx delivery guy of the cell. This little guy is called the kinesin, and he pulls a sack that's full of brand new manufactured proteins to wherever it's needed in the cell — whether it's to a membrane, whether it's to an organelle, whether it's to build something or repair something.
Este es el mensajero de FedEx de la célula: este pequeñín es la quinesina, y arrastra un saco lleno the proteínas recién fabricadas allí donde se necesiten en la célula — ya sea a una membrana, o a un organelo, o bien para construir o reparar algo.
