Does endo- and (or) exocytosis require energy? Do they belong to active / passive transport?

Question

I expect vesicle formation and fusion to require energy input; however, I'm not sure about **_which of endocytosis and exocytosis require energy and how they use the energy input_**.Do they belong to active or passive transport?

Answer 1

Endocytosis and exocytosis require energy. Endocytosis takes particles into the cell and exocytosis takes particles out of the cell and they need energy to do this. Keep in mind, there are three types of transport that do not use energy and they are simple diffusion, facilitated diffusion, and osmosis. I pulled up a video for you. I hope this helps.
