The transport process that utilizes pressure gradients rather than concentration gradients is
A) simple diffusion
B) filtration
C) active transport
D) osmosis
E) phagocytosis

Question

Quizplus · Accepted Answer

Filtration is a transport process that utilizes pressure gradients, such as blood pressure, to move molecules across a selectively permeable membrane. Simple diffusion and osmosis utilize concentration gradients, while active transport requires energy expenditure for movement. Phagocytosis is the engulfment of large particles by cells and is not a type of transport process.
