This week our objectives will be: Ø Sketch a typical cell membrane, label the components, name a term that describes the permeability of this membrane, and describe the factors that determine whether a substance/ particle will pass through the cell membrane. Ø Distinguish between integral and peripheral membrane proteins and list the functions of each. Ø Distinguish between passive and active transport processes and make a quick list comparing the eight processes discussed in terms of energy requirement, direction of concentration gradient, give an example in humans, and if applicable, the significance of each. Ø Define the terms diffusion, facilitated diffusion, osmosis, and filtration, and give an example of each. Ø Describe how gases (oxygen and carbon dioxide) enter and leave human cells. Ø Distinguish between a hypertonic, isotonic, and hypotonic solution and compare the consequences of a human cell being placed in each. Ø Explain how blood passes through the capillaries of our kidneys. Ø Describe how glucose enters and leaves most human cells. |
