Cell Membrane Posters

Cell Membrane Poster

Reference: Campbell (9th Ed.) pages 120, 127

Using colored pencils and/or markers, SKETCH and COLOR the cross-section of a cell membrane onto a large piece of poster paper. In your drawing, you should INCLUDE and LABEL the following:

 Extracellular side of membrane

 Intracellular side of membrane

 Phospholipids

 Integral protein

 Peripheral protein

 Fibers of ECM (collagen, fibronectin, proteoglycan complex)

 Microfilaments of cytoskeleton

 Cholesterol

 Glycolipid

 Glycoprotein

 Simple diffusion of a substance

 Facilitated Diffusion:

o Channel protein (with example of a specific substance passing through)

o Carrier protein (with example of a specific substance passing through)

 Active Transport*:

o Sodium-potassium pump (show Na+ and K+ in drawing)

o Proton pump (show H+ in drawing)

 Cotransport of sucrose-H+

On the back of the poster, LIST and DEFINE the 17 terms that are underlined.
