what is the role of mitochondria?
Energy production The main function of the mitochondrion is the production of energy, in the form of adenosine triphosphate (ATP). The cell uses this energy to perform specific work necessary for cell survive the function . .... . The raw materials used to generate ATP are the foods that we eat, or tissues within the body that are broken down in a process called catabolism. The breaking down of food into simpler molecules such as carbohydrates, fats, and protein is called metabolism. These molecules are then transferred into the mitochondria, where further processing occurs. The reactions within the mitochondria produce specific molecules that can have their electrical charges separated within the inner mitochondrial membrane. These charged molecules are processed within the five electron transport chain complexes to finally combine with oxygen to make ATP. The process of the charged substances combining with oxygen is called oxidation, while the chemical reaction making ATP is called phosphorylation. The overall process is called oxidative phosphorylation. The product produced by this process is ATP. The mitochondria provides energy for the cell. They are known as the powerhouse of the cell because they provide the location for the production of ATP (adenosine tri-phosphate). ATP is produced by aerobic respiration such as glycolysis, the Krebs cycle and electron transport. ATP in turn provides energy for the cell at the molecular level.
Glycolysis, Pentose phosphate pathway, Fatty acid synthesis, Oxadative phosphorylation, Citrtic acid cycle, Beta-oexidation of fatty acids, Keton bodies formation, Gluconeogenesis, Ureasythesis, Cell-apoptosis. Can't think of any other at the moment...
@Templa.tau If your answer is copypasted from a website, try to post the source, one can not know if it's reliable information on a website therefore the reader can take the liberty to decide if it's legit. His source: http://www.epilepsy.com/epilepsy/mitochondrial_functions
Various roles; the most critical is the oxidative phosphorylation and production of ATP. However, there are other roles for the mitochondria in a cell - they have a role in programmed cell death for example - release of cytochrome c from the mitochondria is a trigger for the later stages of apoptosis. (apoptosis is a vital process in the prevention of cancer - cells with damaged DNA undergo programmed cell death rather than carry on, safeguarding the organism as a whole). See the following to have a look at something really interesting: http://en.wikipedia.org/wiki/Apoptosis
Respiration and ATP synthesis via oxidative phosphorylation. Glycolysis and fermentation occur in the cytoplasm, pyruvate oxidation and the citric acid cycle occur in the mitochondria
Yes, auctally you're absolutely right, Fatty acid synthesis, Glycolysis and Pentose phosphate pathway occures in the Cytoplasma. Oxidative phosphorylation occures in the inner mitochondrial membrane. Citrtic acid cycle occures in the mitochrondrial matrix aswell as Beta oxidation of fatty acids, and Keton-Body formation. Gluconeogenesis & Ureasynthesis is a interplay of Mitochrondrial matrix & Cytoplasma.
IT IS KNOWN AS POWER HOUSE OF THE CELL & STORES THE ENERGY IN THE FORM OF ATP & ADP
mitochondria are involved in a range of processes, such as signaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth
