Cis and trans refers to the different faces of a Golgi complex. Vesicles come into the cis face from the ER and leave from the trans face to the plasma membrane or Lysosomes.

What is trans Golgi cistanae?

The trans-Golgi cisternae are the compartments at the furthest end of the Golgi apparatus where proteins and lipids are sorted, processed, and packaged into vesicles for transport to their final destination. It is involved in modifying, sorting, and trafficking molecules within the cell.


What condition is cause by incubation of cells at 20 c blocks the releases of proteins from the trans Golgi?

The condition is likely related to defective vesicle trafficking, particularly in the trans-Golgi network. Incubating cells at 20°C inhibits the proper sorting and transport of proteins within the Golgi apparatus. This can lead to a blockade in the release of proteins from the trans-Golgi and subsequent impairment in secretory pathways.


What are characteristics of Golgi complex apparatus?

a membranous complex of vesicles, vacuoles, and flattened sacs in the cytoplasm of most cells: involved in intracellular secretionand transport


Exocytosis vesicles develop from the membranes of which of the following structures?

Exocytosis vesicles develop from the trans-Golgi network or the endoplasmic reticulum in cells. These vesicles contain molecules that are transported to the cell membrane for release outside the cell.


What are the steps of the secretory pathway?

Protein SynthesisEndoplasmic Reticulum-->cis Golgi cisternae --> medial Golgi cisternae --> trans Golgi Cisternae --> Plasma membraneExtra Cellular SpaceAs they are being synthesized, secretory proteins enter the lumen of the endoplasmic reticulum. From the ER, vesicles transport these proteins to the Golgi, where they are sequentially modified and concentrated in a cis-to-trans direction. Secretory vesicles bud from the Golgi and move along cytoskeletal filaments to eventually fuse with the plasma membrane, secreting their protein cargo. Each of these transport steps requires specialized proteins to ensure that the cargo is sent to the proper location and is able to fuse with the target membrane.

Why it is said Golgi complex has a polarity?

That's because Golgi complex is really spatially orientated (it does not have any random orientation) in the cell - the "cis" part of Golgi is close to endoplasmic reticulum and the "trans" part of Golgi is distant from endoplasmic reticulum. Proteins and lipids coming from endoplasmic reticulum enter Golgi at its "cis" part and across the Golgi network, they are transported towards the "trans" part, from where they are excreted either to other parts of the cell, or more usually, they are transported to plasmatic membrane.


Is Golgi complex present in both plant and animal cells?

Yes, it is present in both, it's used for packaging ribosomes, it has Cis and Trans sides.

What is the significance of the cis and trans sides of the Golgi apparatus?

hahaha....


If you were a protein destined to reach the plasma membrane and you were making your way through the Golgi when suddenly Golgi trafficking was blocked at the trans face what would happen to you?

If you compared the proteins in a cis Golgi compartment with those in a trans Golgi compartment you would find?

contain fewer modifications

How do proteins and other substances get from Endoplasmic Reticculum to Golgi apparatus?

Transport vesicles. Perhaps by motor proteins and entering the trans side of the Golgi.


What organelles possesses a cis and trans side composed of cisternae?

The Golgi apparatus possesses a cis and trans side composed of cisternae. Proteins and lipids are modified and sorted as they move through these compartments, with the cis side receiving materials from the endoplasmic reticulum and the trans side shipping them out to their destinations.


Where does cisternal maturation occur?

Cisternal maturation occurs in the Golgi apparatus, specifically in the cis-Golgi network. This process involves the gradual maturation and transformation of cis cisternae into trans cisternae, allowing for the processing and sorting of proteins within the Golgi apparatus.


Do proteins from the RER have to cross the Cytosol to join the Cis Golgi?

Yes, in vesicles, though there may be confusion between cis and trans here. The confusion may be mine though.
