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.
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 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 amount of mitochondria per cell also varies by cell type, with some examples being: Erythrocytes: 0 mitochondria per cell. [1] Lymphocytes: 3 mitochondria per cell. [7] Egg cell: Mature metaphase II egg cells can contain 100,000 mitochondria, and 50,000–1,500,000 copies of the mitochondrial genome (corresponding to up to 90% of the egg ...
This ratio is variable and mitochondria from cells that have a greater demand for ATP, such as muscle cells, contain even more cristae. Cristae membranes are studded on the matrix side with small round protein complexes known as F 1 particles, the site of proton-gradient driven ATP synthesis. Cristae affect overall chemiosmotic function of ...
[3] [4] MCS are important in the function of the endoplasmic reticulum (ER), [5] since this is the major site of lipid synthesis within cells. [6] The ER makes close contact with many organelles, including mitochondria , Golgi , endosomes , lysosomes , peroxisomes , chloroplasts and the plasma membrane . [ 7 ]
