What is difference between cis trans Golgi complex?
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 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.
What is the narrow flat membranous structure ofa Golgi body is termed as?
The "stacks of pancakes" are vesicles with a trans and cis face.
Does the Golgi apparatus have a polarity or sidedness to its structure and function?
Proteins in the membrane of the Golgi may be sorted and modified as they move from one side of the Golgi to the other. and Lipids in the membrane of the Golgi may be sorted and modified as they move from one side of the Golgi to the other.
What correctly describes an endomembrane function?
Products of the ER are usually modified during their transit from the cis to the trans region of the Golgi apparatus.
What organelles possesses a cis and trans side composed of cisternae?
Golgi apparatus
What is the function of transport vesicle?
The transport vesicle transports proteins from the smooth endoplasmic reticulum to the cis side of the Golgi aparatus. The vesicles move from the Smooth ER to the receiving (cis) side of the Golgi aparatus, and then leave though the trans (shipping) face of the Golgi aparatus .
What is difference between cis trans Golgi complex?
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 are the specialized set of membranous sacs of the Golgi complex derived from?
The sacs of the Golgi complex are formed from vesiclesthat earlier budded off the rough endoplasmic reticulum.When these vesicles reach the Golgi complex, they merge with the sac on the cis side.
What receives transport vesicles on the cis face?
The Golgi body
What is the significance of the cis and trans sides of the Golgi apparatus?
hahaha....
If you compared the proteins in a cis Golgi compartment with those in a trans Golgi compartment you would find?
contain fewer modifications
Can bud off vesicles which form the golgi apparatus?
vesicleSecretory vesicles bud off from golgi. They are small packages of proteins
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.

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.
