for the transport of protein to the Golgi apparatus.

Despite the flow of proteins through the Golgi apparatus, each part of the organelle has specific proteins that are resident in that region. For example, there are specific proteins that are located in the cis cisterna of the Golgi. There are enzymes that are found in the medial cisternae, and others that are located in the trans cisterna or in the trans Golgi net work. This is not a new idea. As we have already mentioned that there are proteins that are resident in the ER.

golgi apparatus modified protein strain(RNA) to become enzyme by shaping and arrange the strain

This organelle is the shipping apparatus for the cell’schemical products.The objective of the GA (Golgi )is to take protein and to add sugar molecules to it, this process is known asglycosylation; it then forms glycoproteins.

The major functions of Golgi apparatus are protein ..

Proteins that require special conditions or are destined to become part of the cell membrane are processed in the ER and then handed off to another organelle called the Golgi apparatus.

Some proteins are retained in the ER (for example, the enzymes that make the oligosaccharides that are added to proteins) These proteins carry an ER retention signal (KDEL or MDEL sequence) at their carboxyl ends. See Table 14-3. Even if they get out of the ER into the cisternae of the Golgi, their ER targeting signal gets them sorted into vesicles that bring them back to the ER. This cis-ward movement of vesicles is called movement.

This tutorial introduces endoplasmic reticulum

(covered by ribosomes)
Golgi Apparatus
The Golgi Apparatus is the post office of protein synthesis it helps:
Sort packages
Ship proteins
Processes & modifies proteins

Where the packages are stored for later use and also transports the packages all over the cell
Ribosomes are free floating or can be attached to the Endoplasmic Reticulum
They have no membrane
When DNA arrives at the Ribosomes protein production commences from the DNA coding
Help breakdown large molecules such as proteins
Organelle Function in Protein Synthesis
By: Alondra Cervantes

DNA holds the coding for making proteins
DNA is found in the nucleus of the cell

mRNA helps transport protein coding to the Ribosomes
Cell Membrane
The cell membrane helps keep the cell in it's shape and protects the cell.
It also allows some types of proteins into the cell
In Conclusion
All of theses organelles are important and significant when it comes to protein synthesis if any of them where not present the production of protein would be in possible.

Scientists are studying many aspects of the ER and Golgi apparatus, including a built-in quality control mechanism cells use to ensure that proteins are properly made before leaving the ER (Source: ).

Sterol regulatory element-binding protein - Wikipedia

To examine aspects of the transfer of secretory proteins from the endoplasmic reticulum to the Golgi apparatus in situ, heterokaryons were formed between Hep G2 human hepatoma cells and WI-38 human fibroblasts. The cells were appropriately treated with cycloheximide before fusion, which emptied them of their respective secretory proteins, serum albumin for the Hep G2 cells and procollagen I for the WI-38 cells. After fusion was complete, the cycloheximide was washed out, protein synthesis was resumed, and the rates of reappearance of serum albumin and procollagen I in the two separated Golgi apparatuses within each heterokaryon were followed by immunofluorescence microscopy. Serum albumin was found to always reappear first in the Golgi apparatus contributed by the Hep G2 half of the heterokaryon, and procollagen I in the Golgi apparatus of the WI-38 half. These results suggest that the endoplasmic reticulum-to-Golgi apparatus transfer in situ is not simply a stochastic process but is either spatially restricted or exhibits cell-type specificity or both.
