Document Summary

**3 classes of membrane proteins: vesicle: (compare to a balloon) may or may not have may contents o. *revise: transition temperature membrane fluidity: high amount of unsaturated or desaturated lipids which means more double bonds = lower transition temperatures. This process is always occurring in our bodies. One present use for liposomes fusing are skin creams. Some lipids can come together and create an island. This hypothesis is very hard to observe. *need to know diagrams (how to label and understand flow of molecules) Passive: no involvement of energy (atp) from high conc. to low conc. Active: requires energy (atp) because it is moving against the gradient from low conc. to high conc. o. *revise concepts: osmosis, hyper osmotic, hypo osmotic, isosmotic, plasmolysis. Don"t need to concern about the specific protein, but that k, na ions can pass through the membrane through this channel o o. If 2 things get pushed together in the same direction co transporter.
