Exocytic
WebExocytosis ( exo = external, cytosis = transport mechanism) is a form of bulk transport in which materials are transported from the inside to the outside of the cell in membrane-bound vesicles that fuse with the plasma membrane. Image modified from OpenStax Biology (original work by Mariana Ruiz Villareal). WebDescription. A transport vesicle that mediates transport from an intracellular compartment to the plasma membrane, and fuses with the plasma membrane to release various cargo …

New plasma membrane proteins WebFeb 5, 2024 · Exocytosis is the process of moving materials from within a cell to the exterior of the cell. This process requires energy and is therefore a type of active transport. Exocytosis is an important process of plant and animal cells as it performs the opposite function of endocytosis.

As an active transport mechanism, exocytosis requires the use of energy to transport material. Exocytosis and its counterpart, endocytosis, are … See more The term was proposed by De Duve in 1963. See more In eukaryotes there are two types of exocytosis: 1) Ca triggered non-constitutive (i.e., regulated exocytosis) and 2) non-Ca triggered constitutive (i.e., non-regulated).
