channel-mediated diffusion Flashcards
1
Q
channel-mediated diffusion
what are some materials which pass through membrane proteins (channels)?
A
- water soluble compounds
* ions
2
Q
even though a channel is required, this is still what type of process?
A
a passive process
3
Q
carrier-mediated transports of what? is it still passive?
A
ions and organic substrates into or out of the cell down their concentration gradient.
it is still passive
4
Q
what can carrier-mediated facilitated diffusion also be called?
A
passive carrier-mediated transport
5
Q
if energy us required to move something in or out of the cell using a carrier protein, what is it called?
A
active transport
6
Q
what is passive transport with a carrier?
A
facilitated diffusion
