Definition of mitochondrion in English English dictionary
A spherical or ovoid organelle found in the cytoplasm of eukaryotic cells, contains genetic material separate from that of the host; it is responsible for the conversion of food to usable energy in the form of ATP
Mitochondria are cellular organelles that lie outside the nucleus and produce energy for the cell through cellular respiration
A eukaryotic organelle that is the site of ATP synthesis and of the citric acid cycle The eukaryotic cellular organelle in which the Krebs cycle and electron transport reactions take place
A small organelle within all human cells that generates the energy
A self-replicating organelle bound by two bilayer membranes that is found in the cytoplasm of eukaryotic cells Mitochondria produce ATP via oxidative phosphorylation reactions carried out by respiratory enzymes located in the inner membrane
The eucaryotic organelle that is the site of electron transport, oxidative phosphorylation, and pathways such as the Krebs cycle; it provides most of a nonphotosynthetic cell's energy under aerobic conditions It is constructed of an outer membrane and an inner membrane, which contains the electron transport chain (See 83)
An organelle found inside the cell, the mitochondrion is the cell's powerhouse All living things need to convert food to energy which many do by respiration, a process akin to controlled burning The resulting energy is used to produce large amounts of ATP, a substance used as a fuel by many other processes
(pl mitochondria) Structure inside a cell that is the location of the cell's energy production machinery
(plural, mitochondria) An organelle in eukaryotic cells that serves as the site of cellular respiration
Eukaryotic organelle responsible for processes of respiration and oxidative phosphorylation
Complex organelle found in most eukaryotes; believed to be descended from free- living bacteria that established a symbiotic relationship with a primitive eukaryote Mitochondria are the site of most of the energy production in most eukaryotes; they require oxygen to function See: double membrane
an energy-producing body as neighbouring with other elements in the cell cytoplasm
A part of the cell (organelle) that is responsible for energy production The mitochondria take care of many specialized tasks, including converting nutrients into energy (Plural form: mitochondria )
Specialized subcellular structures located within body cells that contain oxidative enzymes needed by the cell to metabolize foodstuffs into energy sources Organic - Being composed of, or containing matter of plant or animal origin
Mitochondria are subcellular organelles found in eukaryotes which are between 0 2-0 5 micrometers in length It consists of a double membrane surrounding a matrix, with the inner membrane folded into finger-like projections called cristae The walls of these cristae are the site of energy production for the cell, because of this the mitochondria are called the powerhouse of the cell The mitochondria are found in large numbers in cells with high energy needs The mitochondria are self replicating and contain DNA by which they control synthesis of their own proteins
Small structures within animal cells responsible for the animal's energy metabolism, they convert food into chemicals which cells can use Originally thought to be part of the cell, they are now seen as specialised bacteria, with their own DNA, which have co-operated with animal cells for untold ages Hard science stuff about Mitochondrial DNA
The organelles that generate energy in eukaryotic cells Mitochondria have their own genome encoding a subset of the proteins found in mitochondria; the mitochondrial genome uses an alternate genetic code
Power-producing organelles of the cell, site of catabolic aerobic respiration Mitochondria contain their own chromosome of DNA, which are generally maternally inherited through the egg
A small, intracellular, spherical to rod-shaped cytoplasmic organelle, enclosed by Z membranous spaces; the inner membrane is folded, forming a series of projections called cristae Mitochondria are the principal sites of ATP synthesis; they contain enzymes of the tricarboxylic acid cycle and enzymes for fatty acid oxidation, oxidative phosphorylation, and many other biochemical pathways They contain their own nucleic acids and ribosomes, replicate independently, and code for the synthesis of some of their own proteins
A part of the cell (organelle) that is responsible for energy production The organelle consists of two sets of membranes, a smooth continuous outer coat and an inner membrane arranged in tubules or in folds that form plate-like double membranes (cristae); the principal energy source of the cell, containing the cytochrome enzymes of terminal electron transport and the enzymes of the citric acid cycle, fatty acid oxidation, and oxidative phosphorylation Responsible for converting nutrients into energy as well as many other specialized tasks
n microscopic bodies occurring in the cells of nearly all living organisms that contain enzymes responsible for the conversion of food to usable energy
Cell organelles that metabolize sugars into energy Mitochondria also contain DNA, which is damaged by the high level of free radicals produced in the mitochondria
The small extra-nuclear organelles (bodies) within a cell's cytoplasm that control production of energy from food through the production of ATP (adenosine triphosphate)
(1901): any of various round or long cellular organelles are found outside the nucleus, produce energy for the cell through cellular respiration, and are rich in fats, proteins, and enzymes These are the chemical factories where the products of cellular metabolism are created
A cellular organelle that originated as a gram negative endosymbiotic bacteria Mitochondria have retained a remnant of their once intact bacterial genome The entire mitochondrial genome has been sequenced in Acanthamoeba and Dictyostelium, however attempts to use mitochondrial sequences to classify members of the genus Acanthamoeba have not been completely successful Mitochondria produce ATP using a chemiosmotic mechanism involving electron transport The morphology of mitochondria has been extensively used as a means of classifying amoeba, however it has recently come to light that a single protein (ATP synthetase) determines the morphology of the entire organelle (Paumard et al, 2002),making the classification scheme fragile Paumard, P , Vaillier, J , Coulary, B , Schaeffer, J , Soubannier, V , Mueller, D M , Brethes, D , di Rago, J -P & Velours, J (2002) The ATP synthase is involved in generating mitochondrial cristae morphology , EMBO J 21, 221-230
Semi-autonomous, self-reproducing organelles within the cytoplasm of eukaryotic cells that are bounded by two membranes These organelles are responsible for the energy conversion of most of the cellular energy metabolites into adenosine triphosphate (ATP) by oxidative phosphorylation
