Answer:
Exocytosis, phagocytosis, and pinocytosis
Explanation:
Active transport is when energy is used to move substances across the cellular membrane.
Exocytosis requires energy to remove materials from the cell; it is active.
Phagocytosis also requires energy; it is active.
Diffusion isn't active because it moves materials down their concentration gradient and therefore it doesn't require energy.
Pinocytosis is a form of endocytosis and requires energy; it is active.
