RE: Membrane mediated transportation: Diffusion

in #steemstem7 years ago

Can the permeation of small molecule causes therapeutics across these cellular membranes can occur via passive diffusion and carrier-mediated transport?
nice piece.

Sort:  

I could not get what you are trying to say. Maybe you should reframe the question. thanks

I still don't understand the difference BTW Diffusion and Facilitated Diffusion

diffusion involves a spontaneous movement of molecules in and out of the cell membrane while facilitated diffusion requires the creation of special channels (formed by carrier proteins) for molecules to pass through or through the help of carrier proteins.

Facilitated diffusion is for molecules whose spontaneous diffusion rates are too slow for the cell's requirement, hence there is need to facilitate or catalyze them to meet the cell's demand.

Hope I was able to illuminate your question. Thanks

Yes, thanks
