Acting Potential

Biology pupils take the cell membrane apart piece-by-piece as they complete this worksheet. They describe the structure of the cell membrane and explain the processes that transport materials across it. This phenomenal resource even has...

Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

Building upon the previous video about structure, this resource lays the building blocks of how an action potential is generated and how a signal is transmitted from dendrites through the axon. The topics are quite detailed. Salman Khan...

This is a short correction to the video detailing pumping 3 sodium ions and 2 potassium ions. There is also a letter from a professor giving information about the ratio of 3 to 2 ions and how the concentration gradient is actually the...

Various colors are used on the black background of a Smart Board to compose a drawing of a neuron cell and all its parts while the anatomy of a neuron is described. The function of a neuron is also explained in detail. Show to your...

Wouldn't it be great to learn about cells through osmosis? Introduce learners to the different mechanisms of active and passive transport with a video that shows how the different transports occur across the cell membrane, allowing only...

Your students will love this PowerPoint! Great visuals will support understanding of membrane proteins, cell membranes, active transport, and diffusion. There are a lot of details on each page and all are relevant. The presentation could...

Practice questions covering ion channel effects on neuron membrane potentials.

Materials don't need a password to move through cell membranes! Learners explore how cells move materials across the cell membrane. The video then teaches the detailed workings of both passive transport (specifically diffusion,...

Take your biology class on an exploration of the inner workings of cells with this multimedia presentation. Looking closely at the structure of cell membranes and the processes of osmosis and diffusion, this resource explains for...
