Endocytosis
During endocytosis a small patch of plasma membrane folds in and encloses particles or tiny volumes of fluid at the cell surface.The membrane enclosure then pinches off into the cytoplasm,thereby forming a cytoplasmic vesicle
cells
Large molecules are transported across a cell membrane by the process of process of exocytosis. This is when secretory vesicles secretes large molecules by the fusion of vesicles with the plasma membrane.
Endocytosis is the bulk transfer of materials from inside to outside of a cell with the help of special vesicles. Types of Endocytosis : 1) phagocytosis 2) potocytosis 3) receptor mediated endocytosis
Cells perform endocytosis through membrane movement. Endocytosis is a type of Bulk Transport, which involves the movement of larger particles (vesicles) through the membrane in and out. Endocytosis involves Phagocytosis or Pintocytosis. Phagocytosis: when cells engulf particles via pseudopodia ("false feet"), which is packaged in the membrane into an enclosed sac, and once inside the cell, it becomes a vacuole. Pintocytosis: when cells GULP extracellular fluids and makes them into vesicles. The fluids are unimportant but gulped anyway for the molecules within it.
receptor-mediated endocytosis.

Exocytosis is the process that moves molecules from the inside of the cell to the outside. This process uses sacs or vesicles to move the molecules out.

pinocytosis
Endocytosis moves large and polar molecules, that are unable to pass through a cell's plasma membrane, from the outside of a cell to the inside of a cell. There are three types of endocytosis:Phagocytosis (cell eating)- the process by which a cell engulfs macromolecules.Pinocytosis (cell drinking)- the process by which small dissolved substances enter a cell. Small vesicles pinch off of the plasma membrane into the cell.Receptor-mediated endocytosis- the process by which a cell engulfs molecules specific to its receptor proteins. Molecules bind to specific receptor proteins in the receptor-coated pit. Basically, this type of endocytosis is the same as phagocytosis. The only difference is the molecule specificity, which is sensitive to the type of receptor proteins.See the following link for an animation of these cellular processes and exocytosis:http://bcs.whfreeman.com/thelifewire8e/content/cat_040/0504003.html
receptor-meditated endocytosis
Vesicles filled with a product are excreted from a cell by a process called exocytosis. The opposite is called endocytosis. Both processes require cellular energy (ATP).It is called exocytosis. In this process the Golgi complex packages the macro-molecules in to transport vesicles that travel to and fuse with the plasma membrane. This causes the vesicle to spill the substance out of the cell.It is called exocytosis.
