What organelle is a series of folded membranes covered with ribosomes where proteins are synthesized?
Endoplasmic reticulum
Just to clarify, what order of organelles are involved in the production of a protein?
Endoplasmic Reticulum and Ribosomes Ribosomes are organelles that are responsible for protein translation. They are composed of ribosomalRNA (rRNA), and proteins. Some ribosomes can be found in the cytoplasm (a gel-like substance in which organelles float), while others are found in rough endoplasmic retina.
Which organelle also contains ribosomes, and is responsible for protein synthesis? Function Of Cell Organelles
| A | B |
|---|---|
| ribosomes | Site for protein synthesis |
| mitochondria | Powerhouse of the cell, releases energy into it |
| Lysosomes | Cellular enzymes involved in digestion of food |
| golgi complex | Serves as a package to store cell materials |
Also, do you know where the ribosomes that translate proteins are to be released from cells?
They attach to the endoplasmic side of the endoplasmic-reticulum's cytosolic side. Both bound and free ribosomes can produce proteins by translating mRNA's genetic code into a string amino acids.
What happens to proteins synthesized from free ribosomes found in the cytoplasm and what does it mean?
These proteins pass through the Golgi apparatus, but they remain in the cytosol. C. The proteins don't pass through the Golgi apparatus, but instead move into the nucleus to be processed.

What are the steps of protein production?
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
What 4 organelles are involved in protein synthesis?
Protein synthesis takes place on free 80S ribosomes and on ribosomes attached to rough endoplasmic reticulum in eukaryotic cells.
- Nucleus.
- Ribosomes (not organelles but 'ribonucleoprotein complexes')
- Endoplasmic reticulum (RER)
- Golgi apparatus.
What are two storage organelles?
Two storage organelles are vesicles and vacuoles.
What organelle is considered a factory because it takes in raw?
Chloroplasts turn sunlight, carbon dioxide, and water into food (glucose). What organelle is considered a "factory", because it takes in raw materials and converts them to cell products that can be used by the cell? Cell membrane protects the cell; controls what goes in and out of cell, communication.
What are proteins made of?
Proteins are made up of smaller building blocks called amino acids, joined together in chains. There are 20 different amino acids. Some proteins are just a few amino acids long, while others are made up of several thousands. These chains of amino acids fold up in complex ways, giving each protein a unique 3D shape.
Is the Golgi apparatus involved in protein synthesis?
The Golgi apparatus is a major collection and dispatch station of protein products received from the endoplasmic reticulum (ER). Proteins synthesized in the ER are packaged into vesicles, which then fuse with the Golgi apparatus. The Golgi apparatus is also involved in lipid transport and lysosome formation.
What are two cell structures involved in protein synthesis?
The two cell structures that are involved in protein synthesis are the ribosome and the endoplasmic reticulum. During protein synthesis, mRNA, messenger RNA, is copied from DNA in the nucleus. The mRNA is then processed and exported to the cytoplasm where it is read by the ribosome.
What part of the cell transports proteins?
Answer and Explanation: The organelle that transports proteins is called the endoplasmic reticulum, or ER.
Where do proteins go after ribosomes?
The rough endoplasmic reticulum (RER) which is continuous with the outer membrane of the nuclear envelope plays an important role in the sorting of proteins destined for various other locations in the cell, like the Golgi apparatus, the lysosomes and the plasma membrane.
How do proteins enter mitochondria?
The outer membrane of the mitochondria contains the protein "porin". This forms an aqueous channel through which proteins up to 10,000 daltons can pass and go into the intermembrane space. However, most proteins cannot get into the matrix unless they pass through the inner membrane.
How do proteins move through the cell?
The proteins move through the endomembrane system and are dispatched from the trans face of the Golgi apparatus in transport vesicles that move through the cytoplasm and then fuse with the plasma membrane releasing the protein to the outside of the cell.
How many ribosomes are in a cell?
10 million ribosomes
How are transmembrane proteins made?
This organelle contains the enzymes involved in lipid synthesis, and as lipids are manufactured in the ER, they are inserted into the organelle's own membranes. Similarly, transmembrane proteins have enough hydrophobic surfaces that they are also inserted into the ER membrane while they are still being synthesized.
Do all cells have mitochondria?
Mitochondria are found in the cells of nearly every eukaryotic organism, including plants and animals. Cells that require a lot of energy, such as muscle cells, can contain hundreds or thousands of mitochondria. A few types of cells, such as red blood cells, lack mitochondria entirely.
Where does transcription occur in the cell?
In a eukaryotic cell, transcription occurs in the nucleus, and translation occurs in the cytoplasm.
What are ribosomes where are they located in the cell what is their function?
Function of Ribosomes. Ribosomes are a cell structure that makes protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.
How do ribosomes create proteins?
Ribosomes are the sites in a cell in which protein synthesis takes place. Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
