Facilitated diffusion requires an input of energy and movement is up the concentration gradient
(low to high) movement can be in either direction as it is facilitated by a protein that shuttles the
molecules across the membrane refers to the diffusion of water from an area of low solute
concentration to an area of high solute concentration requires the help of a carrier or channel
protein and movement is down the concentration gradient (high to low)
Solution
The process of spontaneous passive transport of substances across a cell\'s membrane with the
aid of specific transmembrane integral proteins down the concentration gradient is called
Facilitated diffusion. So the last option; facilitated diffusion requires the help of a carrier or
channel protein and movement is down the concentration gradient i.e. high to low is the correct
option..
