What roles do the Golgi Apparatus, Lysosome and Cytoskeleton play in the cell
Answers
Answer:
Golgi apparatus is Post office and Lysosome is eat old and damaged cell.
Answer:
The Golgi apparatus (GA) is a key organelle in biosynthetic membrane transport. It is a morphologically complex compartment composed of a central domain of stacked flattened cisternae, flanked at its entry and exit sites by tubular networks with sorting functions, thecis- andtrans-Golgi networks (CGN and TGN), respectively. Interactions with the cytoskeleton appear to play important roles in both function and morphology of these membranes. Microtubules and their associated motors are involved in determining the position of the GA which is usually associated with the juxtanuclear microtubule organizing center (MTOC). They are also involved in directing incoming and outgoing membrane traffic. Because the GA is the junction at which transport to and from the endoplasmic reticulum (ER) and to the cell surface, as well as endocytic transport, meet, it can be considered a central station of membrane traffic. The role of microfilaments in Golgi function is less well understood. The presence of members of the protein families of spectrin and ankyrin on Golgi membranes, however, indicates that these cytoskeletal structures may be involved in the distinct morphological structure of the GA. The association of myosins with Golgi membranes may furthermore suggest a role of the microfilament system in aspects of membrane transport of this organelle. The roles of the different cytoskeletal structures in Golgi function will be summarized in this review, and their relevance to the organization of membrane traffic discussed.
