BIOL 1201 Lecture : Lecture 11
Document Summary
Readings: pgs 112-122 in campbell biology 9th ed. Mastering biology: homework 9 (due wednesday before 10 am) Continue: cell cytoskeleton from lecture 10 study guide. 7. 3: phospholipid bilayer with integral/peripheral proteins (carbohydrates, steroids, membranes are dynamic fluid mosaic model, selective permeability control transport into and out of the cell. Membrane transport of h2o/solutes: diffusion passive transport of solute molecules from areas of high concentration to low concentration, osmosis . 7. 13: hypotonic bathing solution (hypertonic cell solution, isotonic solutions, hypertonic bathing solution (hypotonic cell solution) What are integral and peripheral membrane proteins: define diffusion, selectively permeable membrane and osmosis, the concentration of solutes in a cell can be 200 mm (total number of moles of solute per liter of cell solution). Use the terms hypotonic, isotonic and hypertonic to answer the following questions. The cell is put in a beaker with a sucrose concentration of 100 mm.
