Active Transport - March 18th 2013

Today we were introduced to the second form of cell transport, active transport.
Active transport is when energy is needed to be used to move molecules from low concentration to high concentration across a cell membrane.  Often in this form of transport, transport proteins are used to aid the process.

Here is an image of active transport.

Here is a link comparing of active and passive transport.

Here is a video showing active transport in terms of the sodium/ potassium pump.
