If false, change the identified word or phrase to make the statement true. Correspondence. Exocytosis is a general term used to denote vesicle fusion at the plasma membrane, and it is the final step in the secretory pathway that typically begins in the endoplasmic reticulum (ER), passes through the Golgi apparatus, and ends at the outside of the cell. Once the load has been released the membrane seals back up again. In contrast, exocytosis is the release of compounds from a cell via vesicle transport. Endocytosis enables the cell to take in the bacteria or fluid droplets from out side the cell and this is important for defense and nutrition respectively. Exocytosis can be constitutive (occurring all the time) or regulated. The fusion by exocytosis of many vesicles to the plasma membrane induces the discharge to the extracellular space of their abundant luminal cargoes. It helps to ingest molecules towards inside of the cell: This process leads to the destruction of the vesicles. Waste material is enveloped in a membrane and fuses with the interior of the plasma membrane. Substances produced inside the cell are processed in an organelle called the Golgi aparatus. Endocytosis.
