How does the mitochondria and ribosome work together?
Its main job is to break down glucose into ATP (energy that the cell can use). The mitochondria does work with other cell organelles in that the ATP is dispersed throughout the cell to power the function of the cell. Specifically, the Ribosomes use the ATP to produce proteins in a process known as protein synthesis.
The RNA's (t, m, and r) then works with ribosomes during translation to make proteins. Endoplasmic reticulum: A series membranes attached to the nucleus and throughout the cytoplasm of a cell that is responsible for protein and protein and lipid synthesis.
- Ribosomes are not organelles and this is very important so it is a good thing that you asked. They are not membrane-enclosed, instead they are macromolecules made of both RNA and proteins.
- The addition of an amino acid to a growing peptide chain requires two ATP molecules for amino acid activation and another two ATP for peptide bond formation and ribosome translation, plus additional costs of about another ATP, for error correction and the synthesis of sequences that are removed during protein
- The ribosomes found in chloroplasts and mitochondria of eukaryotes also consist of large and small subunits bound together with proteins into one 70S particle. These organelles are believed to be descendants of bacteria (see Endosymbiotic theory) and, as such, their ribosomes are similar to those of bacteria.
The mRNA is then sent out of the nucleus and to the ribosomes. When it is time to make the protein, the two subunits come together and combine with the mRNA. The subunits lock onto the mRNA and start the protein synthesis. The process of making proteins is quite simple.
- 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.
- Ribosomes consist of two major components: the small ribosomal subunits, which read the RNA, and the large subunits, which join amino acids to form a polypeptide chain. Each subunit comprises one or more ribosomal RNA (rRNA) molecules and a variety of ribosomal proteins (r-protein or rProtein).
- All cells need proteins to live. Thus, all cells have ribosomes. While a structure such as a nucleus is only found in eukaryotes, every cell needs ribosomes to manufacture proteins. Since there are no membrane-bound organelles in prokaryotes, the ribosomes float free in the cytosol.
Basically, the Golgi apparatus receives protein enzymes from the ER, which are packaged in a vesicle in the Golgi apparatus, processed and finally, pinched off as a Lysosome. Lysosomes then float in teh cytoplasm until they're needed. Lysosomes rely on enzymes created in the cytosol and the endoplasmic reticulum.
- Lysosomes are manufactured and budded into the cytoplasm by the Golgi apparatus with enzymes inside. The enzymes that are within the lysosome are made in the rough endoplasmic reticulum, which are then delivered to the Golgi apparatus via transport vesicles.
- Ribosomes and Endoplasmic Reticulum. Ribosomes are the organelles responsible for protein translation and are composed of ribosomal RNA (rRNA) and proteins. Some ribosomes are found in the cytoplasm, a gel-like substance that organelles float in and some are found in the rough endoplasmic reticulum.
- What substance do Golgi bodies prepare for secretion? Composed of DNA and proteins that form chromosomes during eukaryotic cell division. Long, stringy strand of genes that carries heredity information(DNA) and is formed from chromatin. Holds enzymes created by the cell for digestion.
