    Exercise 1 Cell Transport Mechanisms and Permeability Activity 1: Simulating Dialysis (Simple Diffusion) • Describe two variables that affect the rate of diffusion: Two variables that affect the rate of diffusion are size and concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration to areas

    organisms are made of cells which are surrounded by a membrane. The cell membrane has many functions but the major function is regulating the passage of materials going in and coming out of the cell. These materials consist of sugars‚ salts‚ water and dissolved gases. Most materials move by simple diffusion from high concentration to low concentration. Some substances may be actively transported‚ which requires energy. The diffusion of water across a semi-permeable membrane is called osmosis. Osmosis
