Question 4

A molecule that is important for cell functioning cannot diffuse through the plasma membrane, but needs a protein that can open and close to allow the molecule to diffuse. What is this protein called?

receptor protein

carrier protein

channel protein 

motor protein

Question 5

A molecule needs to enter into the cell but cannot go through the plasma membrane because of its polarity. However, the molecule can bind to a __________ protein and the protein changes shape to allow the particle to move through the membrane.
