Function of the Human Body Learning Objectives

Cellular Physiology 1. Define the distribution of solutes between the intracellular and extracellular compartments. 2. Define passive, active and secondary active transport across the cell membrane. 3. Define the equation and the variables that determine the flux of an uncharged solute by simple diffusion, i.e. Fick’s law of diffusion. 4. Define the role of membrane voltage, concentration gradient and membrane permeability in the movement of charged solutes across the cell membrane. 5. Define the concept of tonicity and osmotic pressure. 6. Define the Nernst equation and how it describes the electrochemical equilibrium of an ion.
