The movement of molecules through a membrane by filtration requires
A)osmotic pressure.
B)hydrostatic pressure.
C)atmospheric pressure.
D)barometric pressure.

Question

Quizplus · Accepted Answer

Filtration involves the movement of molecules through a membrane due to a pressure difference, with the molecule movement occurring from high to low pressure. This pressure difference is typically hydrostatic pressure, which is the force exerted by fluid on the membrane. Osmotic pressure refers to the pressure exerted by a concentration gradient and can result in the movement of water across a membrane, but not necessarily other molecules. Atmospheric and barometric pressure are not directly relevant to the process of filtration through a membrane.
