permability of cell membranes

Question 1

sc, t, and __

what are the three things that effect the perability of cell membranes

Answer 1

solvent concentration
tempurature
PH

Question 2

talk about the bialayer and what substences can get in

how is the permability of cell membranes effected by solvent concentration

Answer 2

the more disolved the phodphalipd bialyer is the more permable the membrane is

Question 3

how has the permability of the cell membrane effeted by the tempurature

Answer 3

it increases the fluidity which then increases the permability

Question 4

how do we regulate tempuraure during the experiment

Answer 4

using a water bath

Question 5

think about teritary structure

how does ph affect the permability of the cell membrane

Answer 5

it changed the shape of the protien structure in the bialayer

Question 6

what can be added to prevent ph effcteing the cells permability

Answer 6

adding buffer solution. it neautralises the ph
