Ribosomes
How ribosomes are work(and explain about Ribosomes)
- the organelles responsible for protein synthesis are called ribosomes. the number of ribosomes in a particular cell varies with the type of cell and its demand for new proteins.
- for example: liver cells, which manufacture blood proteins, contain far more ribosomes than do fat cells, which primarily synthesize lipids.
- individual ribosomes are not visible with the light microscope. in an electron micrograph, they appear as dense granules approximately 25nm in diameter.
- each ribosomes is roughly 60 percent RNA and 40 percent protein.
- Ribosomes, composed of a small and a large ribosomal subunit, both of which contain Ribosomal(RNA) .Free ribosomes are in the cytoplasm, and fixed ribosomes are attached to the endoplasmic reticulum.
- A functional ribosomes consists of two subunits that are normally separate and distinct.
- one is called a small ribosomal subunit
- these subunits contain special proteins and Ribosomal RNA, one of RNA types
why Ribosomes are important
- ribosomes are important because that have a huge part in changing the messenger RNA from the DNA. The ribosomes main job is to produce proteins that are needed for your body to survive.
- Ribosomes are important because this is where proteins are synthesized. Proteins are important for carrying out all of the bodies functions from digesting food to the color of our hair.
