How Changing The Solvent Affects Membrane Permeability Flashcards
1
Q
What impact does surrounding cells in a solvent have on the permeability of their cell membranes?
A
The permeability increases because solvents dissolve the lipids in a cell membrane, so the membrane loses its structure.
2
Q
True or False: Some solvents increase cell permeability more than others.
A
True, e.g. ethanol increases cell permeability more than methanol.
3
Q
True or False: Increasing the concentration of the solvent will also increase membrane permeability.
A
True
