Question and answer
How does passive transport differ from active transport?
Passive transport involves carriers, channels, or direct diffusion through a membrane. This type of transport always operates from regions of greater concentration to regions of lesser concentration. No external source of energy is required. [ In active transport it is possible to go against the concentration gradient. In active transport, a source of energy is required to move the carrier
and its materials. ]
