What is the targeting pathway of insulin?
Endoplasmic Reticulum --> Golgi Apparatus --> outside the cell
Why is the endoplasmic reticulum important in the production of insulin?
Endoplasmic reticulum (ER) or more specific rough endoplasmic reticulum is important due to the presence of ribosomes on the surface of ER. The protein synthesis takes place in the ribosomes but once its "completed" it moves within the interior of the ER. Now ER is important because although the protein synthesis is done still some modifications is required to activate it. A portion of modification is done inside the ER where proteins ( eg. Insulin) are a step closer for activation. hope this helps :)
Where is the er in the cell located?
The Nucleus of a cell
How can you tell rough ER and smooth ER?
The Rough ER has a surface covered by mitochondria - which appear as small circles, and make the surface "rough" in appearance. The Smooth ER does not have these ribosomes, and so the surface is just one smooth line.
What organelle modifies proteins before they are either used by the cell or transported out of the cell?
In a cell the rough and smooth Endoplasmic Reticulum modifies proteins. The Golgi Apparatus also modifies and packages proteins.
What is insulin's target pathway?
cytoplasm to ER to outside the cell
What is the targeted pathway for insulin?
ER>Golgi>Outside of the cell.
What are insulin's targeting pathways?
ER --> Golgi --> Outside Cell
What is the difference between ribosomes in the cytosol and ribosomes in er?
The 'free' ribosomes are for local use within the cell, whereas the ribosomes attached to the ER are transported to other parts of the cell or transported away from the cell.
Unfinished proteins transported from the ER are modified in the cell's?
Golgi apparatus
Can you give me an example of a protein made on the rough ER that is transported out of the cell?
the ribosome
What is the targeting pathway of insulin?
Endoplasmic Reticulum --> Golgi Apparatus --> outside the cell
What cell structures are found on the surface of rough er but not on smooth er?
ribisome
What is a cell orgelle that helps make and package materals to be transported out of the cell?
The organelle is the smooth Er . It packs substances in transport vesicles
What is the cell part of sites of protein synthesis?
Ribosomes in cytoplasm and also the surface of the rough ER
What part of the cell part is the site of protein synthesis?
Ribosomes in cytoplasm and also the surface of the rough ER
What is the route of insulin from its production to its exit from the cell?
The route of the insulin from its production to its exit from the cell is at the pancreatic cells. This is then secreted in the bloodstream.
