10 Questions
Explain the steps of the exocytic pathway, including cargo selection, budding, scission, and final secretion.
The steps of the exocytic pathway involve cargo selection, where specific molecules are chosen for transport, budding where the vesicle forms and encloses the cargo, scission where the vesicle is released from the donor compartment, and final secretion where the vesicle fuses with the plasma membrane to release its contents.
What are the classifications of cisternae in the Golgi apparatus?
The cisternae in the Golgi apparatus are classified as cis, medial, and trans.
What is the function of the cis Golgi network (CGN)?
The cis Golgi network (CGN) is an interconnected network of tubules responsible for receiving molecules from the endoplasmic reticulum and facilitating their modification and sorting.
What is the role of the trans Golgi network (TGN)?
The trans Golgi network (TGN) is responsible for sorting molecules into distinct tubules and vesicles for further transport to their final destinations within or outside the cell.
What is the function of the peripheral membrane skeleton in the Golgi apparatus?
The peripheral membrane skeleton in the Golgi apparatus is responsible for supporting the structure and organization of the Golgi compartments, as well as facilitating the modification and sorting of proteins and lipids essential for cellular processes such as signaling, transport, and metabolism.
Explain the steps of the exocytic pathway for vesicle-mediated transport through the endomembrane system.
The steps of the exocytic pathway include cargo selection, budding, scission, and final secretion.
What are the compartments of the Golgi apparatus called, and how are they classified?
The compartments of the Golgi apparatus are called cisternae and are classified as cis, medial, and trans.
What is the function of the cis Golgi network (CGN)?
The cis Golgi network is an interconnected network of tubules responsible for transporting molecules (take or back).
What is the function of the trans Golgi network (TGN)?
The trans Golgi network is a distinct network of tubules and vesicles responsible for sorting molecules.
What is the peripheral membrane skeleton responsible for in the endomembrane system?
The peripheral membrane skeleton is responsible for modifying and sorting proteins and lipids, essential components of cell membranes, playing crucial roles in cellular processes such as cell signaling, transport, and metabolism.
