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
