|Print out several copies of this figure and use it to take notes regarding voltage and membrane potentials.|
|The sodium-potassium pump (Na+-K+ ATPase) helps the cell maintain concentration gradients of both sodium (higher outside the cell) and potassium (higher inside the cell).|
|Gated channels continue to be investigated by researchers. This image of a gated potassium channel shows four pieces that fit together to barely allow K+ through a narrow channel when the gate is open.
Use this link to visit an interactive animation to learn the role of voltage gated channels in producing an action potential.
|This animation shows the general idea of how voltage-gated sodium channels work(the details of the mechanism may not work exactly this way, but the basic concept is the focus here)|
