Biology 1060 Chapter 7 Membrane Structure and Function

Cell Membrane Describe the properties of the cell membrane –Discuss how their contribute to its function Describe the components of the cell membrane and their arrangements Discuss the current model of cell membranes –Discuss each of the components and their relationship to fluidity

Membrane Proteins Discuss the locations and functions of membrane proteins Describe the mechanism by which membrane is acquired as secretion takes place

Selective Permeability Describe why selective permeability is important –Give several examples of materials that cross Discuss how hydrophobic and hydrophilic molecules are affected by the membrane Describe the importance of transport proteins

Passive Transport Define diffusion –Describe its mechanism and –Describe its importance to the cell Define osmosis –Discuss its importance to the cell Compare and contrast water balance in cells with and without cell walls

Passive Transport Compare and contrast the reactions of cells in a/n –Hypotonic solution –Isotonic solution –Hypertonic solution Evolution Connection p. 140

Facilitated Diffusion Differentiate facilitated diffusion from simple diffusion –Describe the reason facilitated diffusion is important –Compare and contrast all mechanisms of transport across membranes

Active Transport Describe why active transport is needed –Describe how active transport is accomplished Describe the sodium-potassium pump and its effect on the cell Describe how an electrogenic pump helps a cell –Discuss its transport Scientific Inquiry p. 140

Bulk Transport Discuss why bulk transport is necessary Compare and contrast endocytosis and exocytosis Compare the results associated with –Endocytosis –Phagocytosis –Pinocytosis –Receptor-mediated endocytosis Science, Technology, and Society p. 140
