NURSING MSN 570 Study Guide CHAPTER 1 Cellular Biology / NURSING MSN 570 Study Guide CHAPTER 1 Cellular Biology/ NURSING MSN 570 Study Guide CHAPTER 1 Cellular Biology CHAPTER 1 Cellular Biology B) Cellular Permeability: • Is the ability of the cell to allow passage of some substances through the membrane, while not permitting others to enter or exit. • Some substances have free passage in and out of the cells, including enzymes, glucose, and electrolytes. Enzymes are proteins that facilitate chemical reactions in cells, while glucose is a sugar molecule that provides energy. Electrolytes are chemicals that are charged conductors when they are dissolved in water. Failure of these exchange mechanisms can lead to the development of disease. Diffusion - is the movement of solutes—that is, particles dissolved in a solvent—from an area of higher concentration to an area of lower concentration. Simple diffusion will occur until the concentration gradient, which is the difference in concentrations of substances on either side of the membrane, is equal on each side. Solution is made of a solvent and solutes. Solvents dissolve solutes
