What is the main function of Golgi complex?
The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion. In addition, as noted earlier, glycolipids and sphingomyelin are synthesized within the Golgi.
What does the cisternae do?
The cisternae play a crucial role in the packaging, modification, and transport functions for the cell overall. The proteins and polysaccharides that get processed here within the cisterna will then be sent to their specified locations.
What is the major characteristic of the Golgi complex?
The Golgi apparatus is a membrane-bounded organelle with the characteristic shape of a series of stacked flat cisternae. During mitosis in mammalian cells, the Golgi apparatus is once fragmented into small vesicles and then reassembled to form the characteristic shape again in each daughter cell.
What is the origin of Golgi apparatus?
It was discovered in 1898 by Italian physician Camillo Golgi during an investigation of the nervous system. The term “Golgi apparatus” was used in 1910 and first appeared in the scientific literature in 1913, while “Golgi complex” was introduced in 1956.
What is the function of Golgi complex class 9?
1)They are involved in synthesis of cell wall,plasma membrane and lysosomes. 2)It produces vacuoles which contain cellular secretions eg:enzymes,protein,cellulose etc. 3)They act as an area for storage,processing and packaging of various cellular secretions.
What is the role of cisternae in Golgi complex?
Cisternae at the carbohydrate synthesis stage are commonly referred to as medial and trans (Fig. 1). The main function of these cisternae is glycosylation of proteins and lipids, and synthesis of complex polysaccharides (Atmodjo et al.
Which type of cisternae make up the Golgi complex?
Golgi apparatus …are known generally as “cis” (cisternae nearest the endoplasmic reticulum), “medial” (central layers of cisternae), and “trans” (cisternae farthest from the endoplasmic reticulum).
Which of the following best describes a process that occurs within the Golgi complex?
Which of the following best describes a process that occurs within the Golgi complex? The Golgi complex is a membrane-bound structure to which some proteins are moved from the rough endoplasmic reticulum, where they are enzymatically modified before being sent to a cellular membrane.
What does the Golgi complex look like in a plant cell?
It is shaped like a stack of bowls with secretory vesicles on their rims. Specifically, the Golgi apparatus functions by modifying and packaging proteins and lipids into secretory vesicles: small, spherically shaped sacs that bud from its ends.
In which part of Golgi complex proteins are modified?
Protein cargo moves from the ER to the Golgi, is modified within the Golgi, and is then sent to various destinations in the cell, including the lysosomes and the cell surface. The Golgi processes proteins made by the endoplasmic reticulum (ER) before sending them out to the cell.
