Detailed explanation-1: -Exocytosis is an energy-consuming process that expels secretory vesicles containing nanoparticles (or other chemicals) out of the cell membranes into the extracellular space. Generally, these membrane-bound vesicles contain soluble proteins, membrane proteins, and lipids to be secreted to the extracellular environment.
Detailed explanation-2: -Exocytosis’ main purpose is to expel material from the cell into the extracellular fluid; this is the opposite of what occurs in endocytosis. In exocytosis, waste material is enveloped in a membrane and fuses with the interior of the plasma membrane.
Detailed explanation-3: -Exocytosis is typically the secretion of large molecules. These could be proteins and glycoproteins like digestive enzymes and many peptide/polypeptide hormones, each of which must exit the cell to either the extracellular fluid or circulation.
Detailed explanation-4: -The reverse process of moving material into a cell is the process of exocytosis. Exocytosis is the opposite of the processes discussed in the last section in that its purpose is to expel material from the cell into the extracellular fluid.
