All of the following may influence the rate of simple diffusion across a selectively permeable membrane EXCEPT the
A) concentration gradient.
B) lipid solubility of the molecule.
C) temperature.
D) size of the molecule.
E) size of the cell.

Question

Quizplus · Accepted Answer

The size of the cell does not directly influence the rate of simple diffusion across a selectively permeable membrane. Factors that do influence the rate include the concentration gradient, lipid solubility of the molecule, temperature, and size of the molecule, as these affect how easily molecules can move across the membrane.
