5.2: Membrane structure results in selectrive permeability

Question 1

transport proteins

Answer 1

used by hydrophilic/ions molecules in order to pass through without being impeded by the lipid bilayer

Question 2

channel protein

Answer 2

have hydrophilic channel where certain molecules or ions can pass through

Question 3

aquaporins

Answer 3

channel protein that allows for passage of tons of water molecules at a time(water pores)

Question 4

carrier proteins

Answer 4

holds onto their molecules and change shape in order to get them accros the membrane, require ATP (only if going against concentration gradient)
