BIOL 430 Lecture Notes - Lecture 8: Chronic Obstructive Pulmonary Disease, Semipermeable Membrane, List Of Lakes By Volume
Document Summary
K = diffusion constant (depends on solubility of gas and temperature) P2-p1 = difference in partial pressure of gas on either side of barrier to diffusion. D = distance (thickness of barrier to diffusion) Chron"s walls inflamed; too thick for nutrients to get to that wall. Solute travels from higher concentration to lower concentration. Osmosis assuming the membrane contains aquaporins open channels. The movement of water through a semi-permeable membrane from an area of higher water concentration (lower solute) to an area of lower water (higher solute) concentration. Tonicity refers to the ability of a cell to alter its water volume. Particles to how much water is around look at environment. Isotonic cytosol and solution with same relative concentration of solutes. Hypotonic solution with a lower concentration of solutes than cytosol. Hypertonic solution with a higher concentration of solutes than cytosol. Usually refers to the interstitial environment surrounding the cell(s)
