Osmosis- Water diffuses across the membrane, high to low concentration, Water moves from less solute to more solute

Unsaturated Fatty Acid-  carbon chains contain one or more double bonds with a terminal carboxylic group (–COOH)

Cell in Equilibrium has random movement of substances in/out of cell

what type of molecules move easily across the membrane-

Water follows the higher concentrated area

Passive Transport: substances/ions move down its concentration/electrochemical gradient & no energy is needed

Types of Passive Transport: simple/facilitated diffusion & osmosis

Carrier Protein- cell membrane protein involved in facilitated diffusion and active transport of substances out of or into the cell

Aquaporins- integral membrane proteins, water, water specific channel,

Hypertonic- solution with the higher solute concentration is hypertonic, cell to shrink, h20 goes in

Hypotonic- solution with the lower solute concentration, cell to swell, h2o goes out

Diffusion: passive process in which molecules move from high to low concentration

Distilled/Pure Water: no solutes dissolved

Cholesterol- among phospholipids of membrane, minimize effects of temp on fluidity

Integral proteins- perm. Embedded in membrane, channel/transport molecules across membrane, cell receptors?

Transmembrane proteins- integral protein which spans entire membrane, gateway to permit transport of specific substances across membrane
