Diffusion- is the movement of the substance from an area of higher concentration to an area of lower concentration,Osmosis- is the diffusion of water molecule only through a membrane semipermeable cell membranes allow water to pass through them until equilibrium occurs.Facilitated Diffusion- carrier proteins, and channel proteins it occurs when molecule pass through a cells membrane.
It doesn't. (answer by RRU member Cyrem)
Diffusion.
Net diffusion means the total diffusion due to both holes & electrons .
Facilitated diffusion uses integrated proteins that act as channels for ions or molecules to pass through.
Diffusion carried out by protein channel is termed channel mediated diffusionRead more http://www.kgbanswers.com/what-is-channel-mediated-diffusion/4450816#ixzz1EANNtr00
They are the channels by which molecules enter in facilitated diffusion.
In Biology there are three types of diffusion. There are simple, channel, and facilitated diffusion.
facilitated diffusion
It is an integral protein that acts as a channel.
it creates ah channel (:
so molecules can use protein channel to cross a cell membrane-cleo
The scientific meaning of diffusion is when the particles separate/spread out
Facilitated diffusion is the movement a substance from high concentration to low concentration across a membrane through a transporter protein or channel
Facilitated diffusion
NO. aquaporins are pores and are meant for facilitated diffusion.
Its an active transport and use sodium channel generally _____ Diffusion is itself a pathway of travel across a cell membrane. Diffusion can be "simple diffusion" which is simply an ion moving across the membrane anywhere, or "fascilitated diffusion", where an ion moves across the membrane in a specific channel. Either way, diffusion involves the movement of that ion along its concentration gradient and requires no energy. Active transport is not the same as diffusion. Active transport requires energy.
