Hello, I am looking for someone to write an article on Movement of Substances Across the Cell Membrane. It needs to be at least 1750 words. An analysis of the process of osmosis reveals that it is similar to simple diffusion, with the main difference being the presence of the semi-permeable membrane that only allows the passage of water through to the different concentrations (Sperelakis, 2001). Before the process is explained, it is important to note that the water in the cells will always move from the side with a low solute concentration to the area with a high solute concentration. Logically, it should be noted that as the concentration of the solute increase, so does the concentration of the solution, and across different cells, this causes an imbalance, and equilibrium must be restored. Osmosis then occurs to move the water molecules from the highly concentrated side (with low solvent content) to the lower concentrated side (with high solvent content) until the two sides are equally concentrated. Biologically, the side with a high solvent concentration is called the hypertonic solution, the side with the low solute concentration is called the hypotonic solution and equilibrium solutions are called isotonic solutions.
