Definition Of Passive Transport
Passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input.
Compare and Contrast
Active:
-Uses ATP to pump molecules up the concentration gradient
-Transport occurs from a low concentration to high concentration
-Requires cellular energy
Passive:
-Movement of molecules down the concentration gradient
-Occurs from high to low concentration
-Does not require cellular energy
Both:
-Moves oxygen, water, and nutrients into cells and removes waste products
Examples Of Passive Transport
The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis.
