Which Process Does Not Rely on Active Transport

Question

Which process does not rely on active transport?
A) sodium-potassium pump
B) phagocytosis
C) pinocytosis
D) filtration

Accepted Answer

Filtration is a passive process that does not require energy or active transport. It involves the movement of substances across a membrane due to pressure differences. The other three choices all involve active transport, which requires energy to move substances against concentration gradients.
