Tonicity in Chemical Biology

Permeability of a cell membrane

Effective osmotic pressure gradient (correct)

Concentration of solutes inside a cell

Water potential of a solution

Osmotic pressure depends on the direction of osmotic flux

Osmotic pressure is affected by solutes that can freely cross the membrane

Tonicity is influenced only by solutes that cannot cross the membrane (correct)

Tonicity is solely determined by water potential

Pressure exerted by the solutes

Relative concentration of selective membrane-impermeable solutes (correct)

Temperature of the solutions

Size of the solute particles
