Endocytosis and Exocytosis OCR / Edexcel

In this video, we look at endocytosis and exocytosis, which are also called bulk transport. First we look at how endocytosis is used to bring particles across the cell membrane into the cell and then how exocytosis exports molecules from the cell. We then explore why both endocytosis and exocytosis require energy.
