Detailed explanation-1: -Active transport uses energy to transport molecules across the plasma membrane. This uses energy from ATP.

Detailed explanation-2: -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. There are three types of endocytosis-phagocytosis, pinocytosis and receptor-mediated endocytosis.

Detailed explanation-3: -Endocytosis and exocytosis are the bulk transport mechanisms used in eukaryotes. As these transport processes require energy, they are known as active transport processes.

Detailed explanation-4: -There are two types of vesicle transport, endocytosis and exocytosis (illustrated in Figure below). Both processes are active transport processes, requiring energy.

Detailed explanation-5: -Endocytosis methods require the direct use of ATP to fuel the transport of large particles such as macromolecules; parts of cells or whole cells can be engulfed by other cells in a process called phagocytosis.
