Why are ribosomes attached to the endoplasmic reticulum?
Rough Endoplasmic ReticulumThere are two types of Endoplasmic Reticulum:1) Rough ER which has Ribosomes attached to it on the sides and walls. Giving it a "rough" look2)Smooth ER which has no ribosomes. Giving it a "smooth" look
Which of the following are associated with matter and energy transfers in eukaryotic cells?
Mitochondria are associated with energy transfers in eukaryotic cells through the process of cellular respiration. Additionally, the endoplasmic reticulum is involved in the synthesis and processing of proteins and lipids, which are important for cellular function and the transfer of molecules within the cell.
What is the rough ERs job in the animal cell?
The rough ER is the part of the endoplasmic reticulum that has the ribosomes on it.The ribosomes begin synthesizing a protein and stick to the ER so all it does is hold the ribosomes.Source: http://en.wikipedia.org/wiki/Endoplasmic_reticulum#Rough_endoplasmic_reticulum
Why does Golgi apparatus remain in close association with ER?
Products from endoplasmic reticulumn are transported into golgi.So it is important to they to be close.
What is the site of protein synthesis in plant cells?
The site of protein synthesis in plant cells is the ribosomes, which can be found both free-floating in the cytoplasm and attached to the endoplasmic reticulum. It is here that messenger RNA (mRNA) is translated into proteins with the help of transfer RNA (tRNA) and ribosomal subunits.
What does the endoplasmic reticulum do in a plant cells?
the endoplasmic reticulum moves things around in the cellEndoplasmic reticulum are large netwok of membrane bound tubes. Its functions are-Serves as a channel for the transport of materials.Performs certain biochemical activity.Plays a role in detoxifing poisons and drugs.It is a site of protein manufacture.
Ribosomes are attached to the rough part of the endoplasmic reticulum that...?
Ribosomes are attached to the rough endoplasmic reticulum, which is responsible for synthesizing proteins. This association allows the ribosomes to transfer newly synthesized proteins directly into the endoplasmic reticulum for processing and modification before they are transported to their final destination within or outside the cell.
What are the functions and types of endoplasmic reticulum?
The rough endoplasmic reticulum is covered in ribosomes and helps produce most of the proteins. Smooth endoplasmic reticulum does not have these ribosomes, and is almost solely for producing lipids.
What is agranular ER attached to granular ER?
The agranular ER is involved in making lipids and steroids, the granular is involved in making membranes and secreting proteins as they are extensions of the nuclear membrane. The smooth, agranular, and the rough, granular, are continuations of the Endoplasmic Reticulum.
What is the rough endoplasmis reticulum?
The rough endoplasmic reticulum is a network of membranesin the cytoplasm of eukaryotic cells.The membranes enclose a continuous cavity, the lumen, that is separated from the cytoplasm. The lumen of the rough endoplasmic reticulum is continuous with that of the smooth endoplasmic reticulum and with the nuclear envelope.The term "rough" applies to the appearance of the membranes under the electron microscope. They have small, more or less spherical spots attached to them; these are ribosomes. The ribosomes are the sites of polypeptide synthesis. All polypeptides are initially synthesized at free ribosomes in the cytosol, but certain amino acid sequences stimulate special molecules to transfer the ribosomes to the rough endoplasmic reticulum, where polypeptide synthesis continues, with the ribosome embedded in the membrane of the endoplasmic reticulum, and the polypeptide formed in the lumen of the endoplasmic reticulum.Polypeptides synthesized in the rough endoplasmic reticulum form proteins that are destined for secretion or for certain locations within the cell, including the plasma membrane, lysosomes, or the endoplasmic reticulum itself.The rough endoplasmic reticulum also transports materialsthrough the cell. The lumen forms a series of channels through which these materials can move from one place in the cell to another without entering the cytoplasm.
What has ribosomes attached to it and it synthesizes proteins?
In translation, messenger RNA and transfer RNA and ribosomes work together to produce proteins. Ribosomes are very tiny particles that are present in large numbers in all living cells and serve as the site of protein synthesis.
What makes up cells?
Cells are full of many organelles that have different functions. Plant cells have cell walls with a cytoplasm, central vacuole, ribosomes, endoplasmic reticulum, chloroplasts, dna, messenger rna, transfer rna, and smaller vacuoles. Animal cells have a cell membrane, nucleus, nucleolus, ribosomes, endoplasmic reticulum, mitochondria, dna, messenger rna, transfer rna. Unicellular organisms usually have or do not have a cell membrane with various organelles listed above depending on the organism. Hope this helps! -DrkMnlight
What produces the proteins for the cell?
robosomes in the endoplasmic reticulum.

Does the Golgi apparatus make proteins?
No. The Golgi apparatus of a eukaryotic cell primarily modifies proteins delivered from the rough endoplasmic reticulum. It is also involved in the transfer of lipids inside the cell and the formation of lysosomes. A cell's ribosomes are responsible for protein production.
What is the function of rough endoplasmic?
In this question it seemed like you were referring to the organelles on the rough endoplasmic reticulum which, by the way, are called ribosomes. Ribosomes binds to mRNA (messenger RNA) and assembles protein using tRNA (transfer RNA) complex. They are also the sites responsible for protein synthesis. It's been described as a kind of platform where proteins are built. They use the RNA copy of a gene to read it like a 'copy of a blueprint' to construct the protein needed. If that is not what you were looking for then this is the function of the rough endoplasmic reticulum: The rough endoplasmic reticulum is a membranous structure that associates closely with the nucleus. Embedded in the membrane of the structure are ribosomes, this is what gives the "rough" appearance. RNA passes through the ribosomes where its sequence of nucleic acid codes for specific amino acids to be joined up in a specific order. The route through the ribosomes for the amino acid takes them into the membranes of the reticulum where they can be kept together. They are then moved of in vesicles formed from the ER membranes to the Golgi Apparatus to be packaged and processed.
How heat transfer is controlled?
There is a special mechanism that controls heat transfer.
