Explanation

Question 5 of 6

1

The function of membrane proteins is to

Select one of the following:

  • allow all large material across the membranes

  • provide a passage for the polar substances or large molecules to move across the membrane

  • Allow substances that are non- polar substances and large to move across the membrane

  • Regulate only the water balance within the cell
