What are the two functions of rough endoplasmic reticulum?
The reason rough endoplasmic reticulum is coz of ribosomes. The ribosomes cover the surface of rough endoplasmic reticulum and make it appear bumpy under microscopic magnification. Ribosomes are the sites where proteins are created from amino acids. Rough endoplasmic reticulum is connected with the outer envelope of the cell nucleus. The following are the main functions of rough endoplasmic reticulum: 1)The prime rough endoplasmic reticulum function is the production and processing of specific proteins at ribosomal sites that are later exported. 2)As I said before, rough endoplasmic reticulum function involves, creation of two types of proteins. One is the type which fortifies and gets embedded into the reticulum membrane. The other types are water soluble membranes which after creation at ribosomal sites, pass through the membrane and into the lumen. 3)The function of rough endoplasmic reticulum doesn't end there. The proteins that enter are further processed inside, the proteins are folded into the right three dimensional shapes and carbohydrates may be added. 4)The next rough endoplasmic reticulum function is to transport these ready proteins to the sites where the are required. They may also be sent to the Golgi bodies for further advanced processing, through vesicles.

What is a ribosomes?
Ribosomes are small organelles found in the cells of all life forms. They are quite small, only a few hundred nanometers across. It has been theorized that ribosomes were once independent life forms, reproducing on their own, until other chemicals such as carbohydrates and DNA were brought into the fold at a later time. Ribosomes are composed of rRNA (ribosomal RNA, or ribonucleic acid) and other catalytic proteins. Their main function is to produce a variety of proteins from simple genetic instructions which propagate outwards from the cellular nucleolus in the form of messenger RNA (mRNA). Ribosomes float in the cytoplasm of a cell or bind to the endoplasmic reticulum, ribbon-like structures found within the cell.Ribosomes are Parts inside of Cell, they help make proteins.Yes, they are organelles of a cell. they attach themselves onto the Endoplasmic Reticulum, another organelle of a cell. and yes, they synthesize proteins. They are mostly found on the Endoplasmic Reticulum(known as the ER) and the Golgi BodyRibosomes, attached to the ER, 'read' mRNA, and translate it to proteins.The above description about the Endoplasmic reticulum pertains to eukaryotic cells. Prokaryotic cells also have Ribosomes.Ribosomes are organelles used by the cell to produce proteins (protein synthesis). Ribosomes are either floating in the cytoplasm or attached to membranes. In general, free-floating ribosomes produce proteins that are used inside the cell, and membrane-attached ribosomes manufacture proteins for use outside the cell.Ribosomes are the tiny structures reported by palade.These are also called as ergosomes.These are ribo nucleo protein granules produced in nucleolus and moveinto cytoplasm where they may be free or attached to ERribosomes are organelles in which amino acids are hooked together to make proteins.ribosomes are organelles in which amino acids are hooked together to make proteins.ribosomes are organelles in which amino acids are hooked together to make proteins.
Are later and discovered nouns?
No, the words 'later' and 'discovered' are not nouns.The word 'later' is the comparative form of the adjectiveand adverb 'late' (later, latest).The word 'discovered' is the past participle, past tense of the verb to discover. The past participle of the verb also functions as an adjective.Examples:We can take the later train. (adjective)She arrived later than usual. (adverb)I discovered a great little shoe store. (verb)His newly discovered hobby is absorbing all of his time. (adjective)
Organelles that does not participate in protein synthesis?
ChloroplastsMitochondrialysosomescentral vacuolechromoplastleucoplastcentriolesgolgi apparatus (although it may participate later on when transporting the completed protein after its synthesis).
Function of the rough endoplasmic reticulum?
rough endoplasmic reticulum has a function of the following:+it makes and processes proteins that are later distributed throughout the cell.
What is smooth endplasmic reticulum?
Endoplasmic reticulum is an organelle present in cells. There are 2 types: - smooth endoplasmic reticulum - rough endoplasmic reticulum The rough endoplasmic reticulum has ribosomes on its surface whereas the smooth one doesn't

What does the smooth endoplamic do?
The smooth endoplasmic reticulum is used for storage. It creates and stores steroids. It also stores ions for later use. It also is involved in the synthesis of lipids(fats). The lipids are one of the components of the cell membrane. It also controls the movement of newly synthesized proteins through budding. It is a system of tubules and vesicles. In liver cells the SER is involved in breaking down lipid-soluble toxins. In the muscle cells the smooth endoplasmic reticulum controls calcium release.

Why is the rough endoplasmic reticulum so rough?
I have to say people really are getting on my nerves with such questions. Go read your biology textbook. Do not use wiki answers for shortcut to pass your Biology exam. Answer: Rough ER is so called because it contains ribosomes the protein synthesizing machinery in the cell. Smooth ER (I know you will ask this later) is on the other hand without ribosomes attached to its membrane.
What produces protein in a cell?
mostly by the ribosomes and are later translated into the rough endoplasmic reticulum. other proteins are made in the cytoplasm.those proteins have structural functions for transporting into mitochondria or the nucleus.the mitochondria also makes proteins for coding into mitochondrial dna. plants use chloroplasts to make their cell proteins.source:http://en.wikipedia.org/wiki/Cell_biology">http://en.wikipedia.org/wiki/Cell_biology
Where is laminine made in the body?
Laminin is a glycoprotein (compound where a carbohydrate is covalently linked to a protein), and like other protein molecules, it is synthesized by the DNA in the nucleus of every cell and later moved into the cytoplasm of the cell to be attached to and stored in ribosomes and the endoplasmic reticulum.

How does a nucleus?
In Biology, the nucleus of a cell acts as a storage center for DNA in the cell. Think of the nucleus as a storage for the blueprints (the DNA) of the cell rather than a brain. The DNA is stored inside the nucleus until needed for DNA replication. It is then extracted from the nucleus through pores in the membrane and into the endoplasmic reticulum where the DNA replication and later the protein synthesis occur.
