The movement of large molecules out of a cell via vesicles is called exocytosis.
The movement of large molecules out of a cell via vesicles is called exocytosis. Exocytosis is a process by which cells release substances from secretory vesicles to the cell exterior. It plays a key role in various cellular functions such as secretion of hormones, neurotransmitters, and enzymes, as well as the plasma membrane expansion during cell growth.
To understand this process and its term, "exocytosis," we can break down the word itself. "Exo-" means "out" or "outside," and "-cytosis" refers to the movement or transport of substances in or out of cells. Combining these elements, exocytosis describes the active transport of materials out of the cell by using vesicles.
To observe exocytosis, researchers employ various techniques such as fluorescence microscopy, electron microscopy, and molecular biology methods. These techniques allow scientists to visualize the release of vesicles from the cell and study the molecules being transported. Additionally, genetic and molecular approaches can be used to manipulate and study the proteins involved in exocytosis, providing valuable insights into this cellular process.
