A mitochondrion (pl. mitochondria) is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi.Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy. [2]
Mitochondrial DNA is the small circular chromosome found inside mitochondria. These organelles, found in all eukaryotic cells, are the powerhouse of the cell. [1] The mitochondria, and thus mitochondrial DNA, are passed exclusively from mother to offspring through the egg cell.
Mitochondria are essentially universal in the eukaryotes, and with their own DNA somewhat resemble prokaryotic cells. Mitochondria are organelles in eukaryotic cells. The mitochondrion is commonly called "the powerhouse of the cell", [ 30 ] for its function providing energy by oxidising sugars or fats to produce the energy-storing molecule ATP .
Mitochondrion – A membrane-enclosed organelle found in most eukaryotic cells. [7] Often called "cellular power plants", mitochondria generate most of cells' supply of adenosine triphosphate (ATP), the body's main source of energy. Chloroplast – An organelles found in plant cells and eukaryotic algae that conduct photosynthesis.
Cell nucleus: A cell's information center, the cell nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell's chromosomes , and is the place where almost all DNA replication and RNA synthesis ( transcription ) occur.
English: A diagram showing a mitochondrion of the eukaryotic cell. Mitochondria are organelles surrounded by membranes, distributed in the cytosol of most eukaryotic cells. Its main function is the conversion of potential energy of pyruvate molecules into ATP.
Mitochondrial matrix has a pH of about 7.8, which is higher than the pH of the intermembrane space of the mitochondria, which is around 7.0–7.4. [5] Mitochondrial DNA was discovered by Nash and Margit in 1963. One to many double stranded mainly circular DNA is present in mitochondrial matrix. Mitochondrial DNA is 1% of total DNA of a cell.
The microtubule-organizing center (MTOC) is a structure found in eukaryotic cells from which microtubules emerge. MTOCs have two main functions: the organization of eukaryotic flagella and cilia and the organization of the mitotic and meiotic spindle apparatus, which separate the chromosomes during cell division.
