facilitated diffusion Flashcards
1
Q
what do large particles diffuse through
A
carrier proteins or channel proteins
2
Q
where are carrier/channel proteins found
A
in the cell membrane
3
Q
what do carrier proteins do
A
move large molecules across the membrane down their concentration gradient
4
Q
step 1 of carrier protein
A
large molecule attaches to a carrier protein in the membrane
5
Q
step 2 of carrier protein
A
the protein changes shape
6
Q
step 3 of carrier protein
A
releases the molecule on the opposite side of membrane
