Detailed explanation-1: -Both endocytosis and exocytosis need energy in the form of adenosine triphosphate or ATP, used in the movement of the substances in and out of the cell.
Detailed explanation-2: -Endocytosis and exocytosis are active transport mechanisms in which large molecules enter and leave the cell inside vesicles. In endocytosis, a substance or particle from outside the cell is engulfed by the cell membrane. The membrane folds over the substance and it becomes completely enclosed by the membrane.
Detailed explanation-3: -Endocytosis is a type of active transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell. There are different variations of endocytosis, but all share a common characteristic: The plasma membrane of the cell invaginates, forming a pocket around the target particle.
Detailed explanation-4: -Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell. Both endocytosis and exocytosis are active transport processes.
