Passive molecular diffusion occurs when ____.
A) the energy of ATP is added
B) random collisions between molecules occur
C) there are variations in molecular sizes
D) enzymes catalyze their movement
E) vesicles break off from the membrane

Question

Quizplus · Accepted Answer

Passive molecular diffusion is driven by the random thermal motion of molecules, leading to their movement from areas of higher concentration to areas of lower concentration without the need for energy input from ATP, enzymes, or vesicular transport.
