What else can I help you with?
What part of the cell are proteins made from?
Proteins are translated from mRNA in ribosomes. They can either be free-floating ribosomes in the cytosol, or attached ribosomes on the rough ER.
What are the unattached ribosomes in the cytosol?
Free ribosomes.
What bio molecules are in a ribosomes?
Ribosomes translate mRNA to proteins. In eukaryotic cells, the ribosomes attached to the rough endoplasmic reticulum (RER) produce proteins that are either to become part of organelles (such as lysosomes), the plasma membrane, or secreted from the cell. The free, or soluble, ribosomes found in the cytosol produce proteins that remain in the cytosol, e.g., the enzymes involved in glycolysis.
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.
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 are unattached ribosomes in the cytosol called?
Free ribosomes.
Why would a cell have free ribosomes?
Free Ribosomes make proteins that funciton within the the Cytosol.
What part of the cell are proteins made from?
Proteins are translated from mRNA in ribosomes. They can either be free-floating ribosomes in the cytosol, or attached ribosomes on the rough ER.
What is the site of proteins synthesis that is suspended in the cytosol and produces proteins for use within the cell?
Free Ribosomes
Why proteins made by free ribosomes free of carbohydrates?
These proteins are not directed to the Golgi for modification. there are two paths for synthesis of proteins: 1) By free ribosomes in the cytosol. Protein is left in the cytosol with no carbohydrate modifications 2) By ribosomes bound to the ER. The protein is transported into the ER during synthesis and transported to the golgi for modification.
What are the unattached ribosomes in the cytosol?
Free ribosomes.
What is the site of protein synthesis that is suspended in the cytosol and produces proteins for use within the cell?
Ribosomes are the site of protein synthesis that is suspended in the cytosol. They produce proteins for use within the cell by translating mRNA into amino acid sequences.
What is the difference in function between free ribosomes and attached ribosomes?
Free ribosomes are found in the cytosol, which is the fluid portion of the cytoplasm, and are responsible for manufacturing proteins that will function as http://www.answers.com/topic/soluble proteins within the cytoplasm or form structural elements, including the cytoskeleton, that are found within the cytosol.
Which cell organelle where proteins are made?
Ribosomes within the cytosol (if they are free) or within the endoplasmic reticulum (if they are membrane bound) are responsible for making proteins.
Where cell organelle is where proteins are made?
Ribosomes within the cytosol (if they are free) or within the endoplasmic reticulum (if they are membrane bound) are responsible for making proteins.
What bio molecules are in a ribosomes?
Ribosomes translate mRNA to proteins. In eukaryotic cells, the ribosomes attached to the rough endoplasmic reticulum (RER) produce proteins that are either to become part of organelles (such as lysosomes), the plasma membrane, or secreted from the cell. The free, or soluble, ribosomes found in the cytosol produce proteins that remain in the cytosol, e.g., the enzymes involved in glycolysis.
What are the functions of free ribosomes?
Free ribosomes usually make proteins that will function in the cytosol, while bound ribosomes usually make proteins that are exported or included in the cell's membranes. Interestingly enough, free ribosomes and bound ribosomes are interchangeable and the cell can change their numbers according to metabolic needs.
