Which of the following will NOT speed up the net rate of diffusion for glucose into a cell?

B) Increasing the concentration of glucose outside of the cell.
C) Increasing the number of glucose transport proteins within the plasma membrane.
D) Decreasing the concentration of glucose within the cell.

Question

Quizplus · Accepted Answer

Decreasing the number of phospholipids in the plasma membrane will impair the function of the membrane, and may even cause cells to leak, which will slow down the net rate of diffusion. Increasing the concentration of glucose outside the cell, increasing the number of glucose transport proteins within the plasma membrane, and decreasing the concentration of glucose within the cell will all help to speed up the net rate of diffusion for glucose into the cell.
