Transmembrane

Transmembrane

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

Hypotonic

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

Hypertonic

________- solution with the higher solute concentration is ________, cell to shrink, h20 goes in.

Cholesterol

________- among phospholipids of membrane, minimize effects of temp on fluidity.

Cell

________ in Equilibrium has random movement of substances in /out of ________.

Diffusion

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

Fatty Acid

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

Aquaporins

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

Osmosis

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

Carrier Protein

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

Passive Transport

________: substances /ions move down its concentration /electrochemical gradient & no energy is needed.

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)

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
