What is ACTIVE TRANSPORT AND PASSIVE TRANSPORT?
Passive transport is a movement of biochemicals and other atomic or molecular substances across membranes. Unlike active transport, it does not require an input of chemical energy, being driven by the growth of entropy of the system. The rate of passive transport depends on the (semi ...
http://en.wikipedia.org/wiki/Passive_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.
