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.

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.
