Hi help I'm stuck! I need to write an essay that talks about the different types of diffusion across a cell membrane. Specifically I need to compare a neurone cell, with either a blood cell, or a epithelial cell. My tutor has given some strong hints that she would prefer a comparison of a neurone with a blood cell though. (I'm not sure if she means red or white however?) as both of these apparently show the full range of difference membrane transport methods. I seem to be doing OK with Neurones as there appears to be plenty of information out there, however I'm having a terrible time sourcing any information on the full range/function of membrane transport in blood cells.

 

Can anyone please point me to some sources where I might be able to find out something about this?

Well what diffuses in and out of red blood cells mainly? We need it to live, you can do a google search on diffusion into blood cells and there is lots of info there on how it occurs etc.
