question 13

Multiple Choice

Which of the following statements regarding the diffusion of a nonpolar solute X across a cell membrane is correct?

• A)At equilibrium,the net flux of X across the cell membrane is zero.
• B)At equilibrium,X will cease moving across the cell membrane.
• C)Solute X will be unable to reach equilibrium because it is nonpolar.
• D)Solute X will reach equilibrium,but the concentration will be much higher on the inside of the cell because of the smaller volume.
• E)At equilibrium,movement of X across the membrane will be much faster in one direction than in the other.
