Explain the structure and function of Golgi bodies
Answers
ANSWER :
The Golgi body is an organelle found in most eukaryotic cells. The Golgi body has a number of functions, including sorting and processing proteins. Proteins are synthesized in the rough endoplasmic reticulum, then they travel to the Golgi body. While in the Golgi body, they are processed and sent throughout the cell.
Structure :
Under the electron microscope, the Golgi apparatus is seen to be composed of stacks of flattened structures that contain numerous vesicles containing secretory granules.The Golgi apparatus is morphologically very similar in both plant and animal cells. However, it is extremely pleomorphic: in some cell types it appears compact and limited, in others spread out and reticular (net-like).Typically, however, Golgi apparatus appears as a complex array of interconnecting tubules, vesicles, and cisternae.
Function :
Golgi vesicles are often, referred to as the “traffic police” of the cell. They play a key role in sorting many of the cell’s proteins and membrane constituents, and in directing them to their proper destinations.
To perform this function, the Golgi vesicles contain different sets of enzymes in different types of vesicles— cis, middle and trans cisternae—that react with and modify secretory proteins passing through the Golgi lumen or membrane proteins and glycoproteins that are transiently in the Golgi membranes as they are en route to their final destinations.The Golgi apparatus hence acts as the assembly factory of the cell where the raw materials are directed to the Golgi apparatus before being passed out from the cell.
