Net Movement Biology

Molecules tend to move all the time in all directions, and this applies to water molecules which are moved during osmosis, and all types of molecules which are moved during diffusion.In both cases there is a driving force which forces the molecules to move in a specific direction. This does not mean that all molecules will move this way as still some are moving in the opposite direction. The number of the molecules moving in the direction of the force minus the number of the molecules moving in other directions is the net movement of the molecules.

Cell Membranes Problem Set

The figures show what can happen when animal or plant cells are placed in an aqueous solution. Water can move across membranes, but polar solutes dissolved in water cannot. The net movement of water (osmosis) is in the direction of increased solute concentrations. An easy way to visualize this rule is simply that the net water movement is from an area of high water concentration (little dissolved solute) to an area of low water concentration (high levels of solute).

Visking tubing is an artificial partially permeable membrane:

smaller molecules like water and glucose pass through its microscopic holes

larger molecules like starch and sucrose cannot pass through it

The slideshow shows a typical experiment using Visking tubing and sucrose solution:

Biology

This section attempts to explain the Hodgkin-Huxley experiments from a biological perspective. Hodgkin and Huxley's work with the giant squid axon was the first to use mathematical models to represent biological systems. Due to Hodgkin and Huxley's findings, we are able to understand how an action potential propagates along a nerve and the functions of their associated ion channels.

Osmosis

So osmosis is the diffusion of water through semi permeable membrane. And this is something that a lot of teachers will spend a little bit of time on but then they'll hammer you with on a test. Because it is really kind of unusual when you first approach it a lot of kids don't really get what it means, but to the teachers it's pretty obvious. So let me see if we can help you figure this out. So what this is all about is a special case of diffusion, you know diffusion is but why is it specifically water? And that's because water has the ability to go through a number of different membranes. This black line here that I drew in I'm using it to represent some kind of membrane. Well it's a cell membrane, a special kind of plastic or dialysis tube whatever.
