Question

what are the differences between trans cisternae and cis.​

Answer 1

Answer:

The key difference between Cis and Trans Face of Golgi Apparatus is that the Cis face of Golgi apparatus is the receiving side of the vesicles from the rough ER to the Golgi apparatus while the Trans Face of Golgi Apparatus is the shipping side of the vesicles filled with proteins from the Golgi apparatus to other places.

Golgi apparatus is one of the cell organelles. Therefore, it consists of vesicles and cisternae. It is the cell organelle that involves sorting and packaging of proteins intracellularly before transporting into some other place. Endoplasmic reticulum forms vesicles and handovers to the Golgi apparatus. The cis face of the Golgi apparatus receives vesicles, and they coalesce to form cis cisternae. Cisternae mature and move in the direction of cis to trans face. From the trans face of the Golgi apparatus, vesicles leave from Golgi apparatus carrying specific proteins to other places.

Answer 2

Answer:

The cis face of Golgi apparatus is the receiving face of the Golgi apparatus to which the vesicles from the endoplasmic reticulum empty their content. Whereas, the trans face of Golgi apparatus is the existing face of the Golgi apparatus from which the vesicles leave the Golgi apparatus.

Shape

Based on the shape, the difference between cis and trans face of Golgi apparatus is that the cis face of Golgi apparatus is convex in shape while the trans face of Golgi apparatus is concave in shape.

Direction

Also, the cis face of Golgi apparatus faces the endoplasmic reticulum while the trans face of Golgi apparatus faces the cytoplasm. Thus, this is another difference between cis and trans face of Golgi apparatus.

Function

Moreover, the cis face of the Golgi apparatus receives vesicles from the endoplasmic reticulum while the vesicles leave the Golgi apparatus from its trans face. Functionally, this is the difference between cis and trans face of Golgi apparatus.

Type of Proteins

Another major difference between cis and trans face of Golgi apparatus is that cis face of the Golgi apparatus receives immature or unmodified proteins while mature or the modified proteins leave the trans face of Golgi apparatus.

Conclusion

In conclusion, the cis face of Golgi apparatus is the receiving face of the Golgi apparatus to which the vesicles from the endoplasmic reticulum empty their content while the trans face of Golgi apparatus is the existing face of the Golgi apparatus from which the vesicles leave the Golgi apparatus. Therefore, immature proteins enter the Golgi apparatus from its cis face and leave the Golgi apparatus from its trans face. Hence, the main difference between cis and trans face of Golgi apparatus is their role in protein maturation.
