The permeability of a lipid bilayer for glucose is 10-8 cm/sec. Consider a cell whose glucose transporter is knocked out. If it is placed in a solution that contains 1 mM glucose, how many glucose molecules will enter the cell in 10 seconds? Assume that the cell contains no glucose and the surface area of its plasma membrane is 5 Î¼m2.

Please give a thorough explanation.
