What is tonicity a measure of in chemical biology?
What is tonicity a measure of in chemical biology?
- Permeability of a cell membrane
- Effective osmotic pressure gradient (correct)
- Concentration of solutes inside a cell
- Water potential of a solution
How does tonicity differ from osmotic pressure?
How does tonicity differ from osmotic pressure?
- 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
What determines the direction and extent of osmotic flux in tonicity?
What determines the direction and extent of osmotic flux in tonicity?
- Pressure exerted by the solutes
- Relative concentration of selective membrane-impermeable solutes (correct)
- Temperature of the solutions
- Size of the solute particles
