Sodium Potassium Pump - Active Transport
This Biology video tutorial explains how the sodium potassium pump works inside the cell membrane. This protein based pump is an example of active transport which requires the use of ATP energy to power the movement of particles up against the concentration gradient - that is to move the

How Does a Hydraulic Ram Pump Work?
A quick description and demo of this ingenious pump. A hydraulic ram is a clever device invented over 200 years ago that can pump water uphill with no other external source of power except for the water flowing into it and there is a way to take advantage of this normally inauspicious eff
