Passive Transport in Biology | Passive Transport Overview, Endocytosis and Exocytosis Across the Cell Membrane. Active transport is an active process that requires energy in the form of ATP, while diffusion is a passive process that does not require any energy. This means ATP is indirectly used for the transport of the molecule against its concentration gradient. It is usually powered by ATP. Enrolling in a course lets you earn progress by passing quizzes and exams. During diffusion (passive or facilitated), substances pass through the plasma membrane until some sort of equilibrium is achieved. Which transport method would be the most effective in moving this food particle into the cell?
