One of the examples of facilitated
is the entrance glucose
from the into cells. Glucose
blood binds to permeases
(hexose-transporting permeases)
in the cell and by
diffusion by these proteins
enters the cell play its metabolic
.

Facilitated diffusion resembles
catalysis because the
substances bind to like
substrates bind enzymes and in
, after one transport is
concluded, the is not
consumed can perform other
transports.
