Introduction The smallest functional unit of life is the definition of a cell. Smaller than the cell are the chemical processes that allow the cell to live. While cell have many different functions, the most basic is making proteins which produces energy by the devouring of glucose. The most interesting part of the cell, because of its complexity, would have to be the plasma membrane. Not only is it selectively permeable, but it protects the cell too. The membrane keeps the shape of the cell; some even consider it the skin of the cell. The plasma membrane does many things, but the main thing is it allows the diffusion of molecules.

Hypothesis 2: The number of carrier proteins will increase if the glucose diffusion rate increases, only if number of carrier proteins correlates to facilitated diffusion.
Hypothesis 3: The rate of osmosis for the solutions increases, if there is an increase in the MWCO’s and pressure for different solutes.
Hypothesis 4: If the MWCO’s increase the pore size, the rate of filtration will increase, but if there is an increase in filtration residue, there will be a decrease in filtration.
Hypothesis 5: There will be an increase of the amount of solute diffused, only if the ATP inside the cell is increased.

In the third run, the Na+/K+ pumps stopped working, do that there was no K+Cl-, causing there to be no solutes to be able to diffuse. The fourth run the rates of diffusion of the solute increased, since the Na+/K+ pumps increasing 300 pumps additionally increased. In the fifth run, the diffusion of glucose in the cell was allowed by the glucose carriers addition, but the rate of diffusion wasn’t affected, but the diffusion rate of the glucose was only dependent on the diffusion rate of Na+ from the Na+/K+
