Which of the following will NOT speed up the net rate of diffusion for glucose into a cell?
A) Increasing the concentration of glucose outside of the cell.
B) Decreasing the number of phospholipids in the plasma membrane.
C) Decreasing the concentration of glucose within the cell.
D) Increasing the number of glucose transport proteins within the plasma membrane.

Question

Quizplus · Accepted Answer

Decreasing the number of phospholipids in the plasma membrane would actually slow down the rate of diffusion for glucose into the cell, as it would make the membrane less permeable to glucose. Increasing the concentration of glucose outside of the cell, decreasing the concentration of glucose within the cell, and increasing the number of glucose transport proteins within the plasma membrane would all speed up the net rate of diffusion for glucose into the cell.
