Cell Membrane and Protein Function

Front

Components of a phospholipid bilayer

Back

Phospholipids, proteins, cholesterol

Front

Interaction of membrane protein components with water vs fatty acids

Back

Hydrophilic components interact with water; hydrophobic components interact with fatty acids

Front

Cell adjustment of saturation and cholesterol in response to temperature

Back

Cells adjust membrane fluidity by altering lipid saturation and cholesterol content

Front

Diffusion and net movement of solute and water

Back

Diffusion predicts movement from high to low concentration

Front

Simple diffusion vs facilitated diffusion vs active transport

Back

Simple diffusion: passive, no energy; facilitated diffusion: passive, uses transport proteins; active transport: requires energy

Front

Path of protein after it leaves ER

Back

Protein travels to the Golgi apparatus, then to its final destination

Front

Consequences of preventing proper cellular localization of protein

Back

Can lead to diseases or dysfunction due to improper protein function

Front

HIV attacks human T-cells (part of the immune system).

Back

HIV is a virus that reproduces within our cells, destroying part of the immune system over time.

Front

Effect of HIV on the immune system.

Back

HIV leaves the person susceptible to microbes that wouldn’t normally have harmed them.
