2.15c Concentration gradients and cells

1. Scenario a- our cell is surrounded by a 5 % glucose solution.
2. The glucose molecules will move through the cell membrane through diffusion from a high concentrated to a low concentrated region.
3. Scenario b-If we increase the concentration to a 10% glucose solution, then there will be many glucose molecules around the cell.
4. The frequency through which the molecules collide with the cell and enter it is much greater than the frequency in scenario A therefore the rate of diffucion is higher in scenario B because we ahave a greater concentration gradient.
