The functions of mitochondria: diverse and amazing
Energy is necessary for any process in a living body, be it a heartbeat or a barbell in the gym. For this work you need to thank the small strange organelles - mitochondria. They are strange because they were once parasites. And they became symbionts, making possible the effective work of the body cells.
Where does an athlete have strength
The main function of mitochondria is the production of energy concentrated in ATP molecules. Chemists use the name "oxidative phosphorylation" for this process. Mitochondria are sufficient in all cells of the body, but in some there are a lot of them - in muscle cells. Moreover, the number of mitochondria can grow with an increase in human fitness. That is, endurance increases not due to the growth of muscle tissue, but by improving local energy production. But this does not exhaust the functions of mitochondria.
Own or others?
The protein that makes up this organelle is very different from the protein of the rest of the cell. Mitochondria have their own genetic code, which is inherited at the level of the egg from the mother's organelles.Maybe that's why wise Jews consider kinship by mother - the total energy of a person is genetically dependent on the ancestors of the female sex. Therefore, young men should carefully look at the brides.
What is the structure and function of mitochondria, what is the connection between them? Mitochondria has several compartments, which are separated by membranes. The most important thing between the inner and outer surface is oxidative phosphorylation. The outer membrane is always permeable to almost all metabolites, the inner membrane is only for oxygen, water and carbon dioxide. On the inner surface is a complex that synthesizes ATP. Also inside is the genetic material of the mitochondria. It also has its own technical “arsenal”, which provides protein synthesis for its own needs.
Cell metabolism and maintaining its constant composition is a complex process. The functions of mitochondria, among others, include the storage of calcium ions. These charged units are required by the cell in different parts of it in different concentrations. If the balance is disturbed somewhere, then the mitochondria is “divided” by calcium ions.Thus, the described organelles are involved in maintaining homeostasis.
The functions of mitochondria also include participation in the synthesis of components necessary for the body. So, they play a significant role in the creation of new blood cells, and also of hormones - estrogen and testosterone. In liver cells, mitochondria have amazing enzymes that neutralize the toxic ammonium salts that come to the liver. In addition, the functions of mitochondria are also associated with the process of programmed cell death - apoptosis. If something is wrong with the organelles, there may be problems with whole organs of the body.
Sun as a danger
Very many diseases have a hidden cause in the disruption of the mitochondria.
