What is channel-mediated diffusion a subtype of?
Diffusion carried out by protein channel is termed channel mediated diffusionRead more http://www.kgbanswers.com/what-is-channel-mediated-diffusion/4450816#ixzz1EANNtr00
Diffusion with a channel protein?
They are the channels by which molecules enter in facilitated diffusion.
What are the types of diffusions?
In Biology there are three types of diffusion. There are simple, channel, and facilitated diffusion.
A molecule such as glucose must use a protein channel to cross through a cell membrane?
facilitated diffusion
What biomolecule is responsible for facilitated diffusion?
It is an integral protein that acts as a channel.
What describes a way proteins behave in a facilitated diffusion?
it creates ah channel (:
Why do you have diffusion?
so molecules can use protein channel to cross a cell membrane-cleo
What is facilitated diffusion across the phospholipid membrane?
Facilitated diffusion is the movement a substance from high concentration to low concentration across a membrane through a transporter protein or channel
The proccess by which a protein channel allows molecules to cross the cell membrane is called?
Facilitated diffusion
Does Aquaporin channel activity require energy?
NO. aquaporins are pores and are meant for facilitated diffusion.
Ions diffuse across membranes down their what?
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.
What moves products through a cell membrane?
Diffusion, facilitated diffusion, Osmosis and Active Transport. Diffusion moves non-polar molecules across the cell membrane down a concentration gradient. Osmosis moves water across the cell membrane through a channel formed by aquaporins called a protein channel, down the water potential gradient. Active moves the non-polar molecules against the concentration gradient, in contrast to diffusion. Lastly, facilitated diffusion moves polar molecules across the cell membrane through creating protein channels in the cell membrane from specific proteins. ETC, glucose transporters bind to form a protein channel for glucose to diffuse through, after which the proteins disperse. That should be all, hope it was of help!
