AP bio vocab quiz 6

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
