Active needs a carrier protein and more energy

# data[].attributes.headline
Molecules can pass through the concentration gradient depending on which way it is going (down or up). Going up it requires more energy because the molecules don't want to be near other molecules which it would be going towards.

Passive transports is from high to low concentration and Transport is from low to high concentration

# data[].attributes.body
Passive transport is when the concentration goes from high to low. Active transport is the opposite and goes from low to high concentration. Active transport also needs more energy than passive transport.

The concentration gradient is how the molecules move. up=to a higher concentration, down=to a lower concentration. Most transport of molecules is down, but some go up.

# data[].attributes.body
The difference is that facilitated diffusion is more complex than the simple diffusion.

# data[].attributes.body
The concentration gradient exists when there is a difference between the concentration of a particle on either side of a membrane. This affects cell transport as particles move along the gradient from high to low concentration in order to eliminate the gradient and achieve equilibrium.

# data[].attributes.body
The Concentration gradient is basically molecules moving through the membrane, side to side, to reach an equilibrium on both sides. Its involved in transport because molecules pass through proteins in the cell membrane as well as phospholipids to travel.
