What are the sites for protein synthesis?
Protein synthesis occurs in the ribosomes, specifically in the cytoplasm of the cell. Some proteins are synthesized in the rough endoplasmic reticulum (ER) when destined for secretion or insertion into membranes.
Are ribosomes always attached to the RER?
No, ribosomes are not always attached to the rough endoplasmic reticulum (RER). While ribosomes are primarily found on the surface of the RER, where they synthesize proteins destined for secretion or membrane insertion, free ribosomes also exist in the cytoplasm. These free ribosomes synthesize proteins that function within the cytosol. The attachment of ribosomes to the RER is a dynamic process that occurs based on the specific needs of the cell.
Are ribosomes found on the RER?
yes they are attached with RER and therefore give the rough appearance to them as compared wtih SER
What are the sites of protein synthesis in cells?
Protein synthesis occurs in the ribosomes of cells. In eukaryotic cells, this process mainly takes place in the cytoplasm, while in prokaryotic cells like bacteria, it occurs in the cytoplasm as well. Additionally, in eukaryotic cells, proteins that are destined for secretion or for membranes are synthesized in the rough endoplasmic reticulum.
Where is the location of ribosomes?
Ribosomes are found in several locations within a cell. They can be freely floating in the cytoplasm, where they synthesize proteins for use within the cell. Additionally, ribosomes are also bound to the endoplasmic reticulum, specifically the rough ER, where they produce proteins destined for secretion or for use in the cell membrane. In eukaryotic cells, ribosomes are also present in mitochondria and chloroplasts, reflecting their evolutionary origins.

What produces protein that will be secreted by the cell?
A hormone destined for secretion from the cell would be manufactured by ribosomes that are attached to the endoplasmic reticulum. The endomembrane system includes Golgi apparatus, lysosomes, vacuoles, and the endoplasmic reticulum.

Some ribosomes are free in the cytoplasm while others line the membrane of the?
endoplasmic reticulum. Free ribosomes synthesize proteins for use within the cell, while membrane-bound ribosomes (attached to the endoplasmic reticulum) synthesize proteins that are destined for secretion or insertion into cell membranes.

Additionally, ribosomes are also bound to the endoplasmic reticulum, specifically the rough ER, where they produce proteins destined for secretion or for use in the cell membrane. In eukaryotic cells, ribosomes are also present in mitochondria and chloroplasts, reflecting their evolutionary origins.
What is the difference between ribosomes in the cytosol and ribosomes in er?
Ribosomes in the cytosol synthesize proteins for immediate use within the cell, while ribosomes attached to the endoplasmic reticulum (ER) synthesize proteins that are destined for secretion or insertion into the cell membrane. The presence of ribosomes on the ER allows for co-translational protein processing and modification.
What happens after ribosomes pass into the cytoplasm?
After ribosomes pass into the cytoplasm, they can either remain free-floating and synthesize proteins in the cytosol or become attached to the endoplasmic reticulum to form rough endoplasmic reticulum (RER). Ribosomes on the RER are involved in synthesizing proteins destined for secretion or insertion into the cell membrane.
How does the function of free ribosomes differ from the function of ribosomes attached to other organelles?
Different proteins are produced on free-floating ribosomes than on ones attached to the rough endoplasmic reticulum (ER). In a general sense, proteins that will be used at the ER will be produced on attached ribosomes. Proteins that are meant for secretion will be made on free-floating ribosomes.
What cell parts are involved in protein synthesis and where are they made?
Protein synthesis occurs in the ribosomes, where mRNA is translated into proteins with the help of tRNA molecules. Ribosomes can be found in the cytoplasm as free-floating ribosomes or attached to the endoplasmic reticulum. Proteins that are destined for secretion or integration into membranes are made by ribosomes attached to the endoplasmic reticulum, while proteins needed for the cell's internal use are made by free ribosomes in the cytoplasm.
Is a series folded membrane pathways spotted with ribosomes?
Yes, a series of folded membrane pathways studded with ribosomes refers to the rough endoplasmic reticulum (RER). The RER is involved in the synthesis and processing of proteins destined for secretion or for use in the cell membrane. Its ribosomes give it a "rough" appearance under a microscope, distinguishing it from the smooth endoplasmic reticulum, which lacks ribosomes and is involved in lipid synthesis and detoxification processes.
