mitochondrion

mi·to·chon·dri·on

 (mī′tə-kŏn′drē-ən)
n. pl. mi·to·chon·dri·a (-drē-ə)
A spherical or elongated organelle in the cytoplasm of nearly all eukaryotic cells, containing genetic material and many enzymes important for cell metabolism, including those responsible for the conversion of food to usable energy.

[New Latin : Greek mitos, warp thread + Greek khondrion, diminutive of khondros, grain, granule; see ghrendh- in Indo-European roots.]

mi′to·chon′dri·al (-drē-əl) adj.

mitochondrion

(ˌmaɪtəʊˈkɒndrɪən)
n, pl -dria (-drɪə)
(Biology) a small spherical or rodlike body, bounded by a double membrane, in the cytoplasm of most cells: contains enzymes responsible for energy production. Also called: chondriosome
[C19: New Latin, from Greek mitos thread + khondrion small grain]
ˌmitoˈchondrial adj

mi•to•chon•dri•on

(ˌmaɪ təˈkɒn dri ən)

n., pl. -dri•a (-dri ə)
an organelle in the cell cytoplasm that has its own DNA, inherited solely from the maternal line, and that produces enzymes essential for energy metabolism. Abbr.: mt See diag. at cell.
[1900–05; < Greek míto(s) thread + chóndrion small grain]

mitochondrion

mi·to·chon·dri·on

(mī′tə-kŏn′drē-ən)
Plural mitochondria
A structure in the cytoplasm of all cells except bacteria in which food molecules are broken down in the presence of oxygen and converted to energy in the form of ATP. Mitochondria contain their own DNA. See more at cell.

mitochondrion

(pl. mitochondria) A rod-shaped organelle inside a cell that is a site of energy release.

A diferenca se da pelo fato de o TCL serem dependente da carnitina para o transporte mitocondrial, enquanto o TCM e transportado pela mitocondria interna independente da carnitina-acil-transferase (Assuncao, 2009).
(2011), a atividade antifungica dos extratos e oleos essenciais esta relacionada a sua propriedade hidrofobica, o que significa que ao entrar em contato com o fungo, os componentes do extrato ou oleo interagem com a mitocondria e com os lipideos da membrana plasmatica, alterando sua permeabilidade, causando disturbios estruturais, o que pode promover a exposicao do conteudo celular, inclusive do nucleo.
Tambien se reportan otros mecanismos de citotoxicidad, al utilizar la acetogenina escuamocina (bis-THF) en la modulacion de la fosforilacion de histona 3 (H3) al desregular la expresion de la proteina aurora B y la proteina quinasa activada por mitogenos (pMSK1), que sobre-expresadas disminuyen la fosforilacion en las posiciones H3S10 y H3S28 H3; consecuente arresto del ciclo celular en G1 y activacion de la apoptosis por vias intrinsecas (a traves de mitocondria) y extrinsecas (ligandos de muerte celular) activando caspasas 8 y 9 (45).
Otro supuesto relativamente similar (de hecho, en algunos casos puede englobarse en el caso anterior, ya que supone un cambio en el genoma de un ovulo) es el que se refiere a los casos de transferencia mitocondrial encaminados a resolver problemas ligados a patologias de la mitocondria (18), que acaban generando los llamados "ninos de tres padres" (19).
Quando em condicoes aerobias e oxidado na mitocondria. Quando em condicoes anaerobias, o piruvato e transformado em lactato, que e responsavel pela regeneracao da coenzima NAD+ (nicotinamida adenina dinucleotideo), que recebem eletrons de NADH, permitindo o funcionamento da via glicolitica.
En todos estos parasitos, la regulacion del [Ca.sup.2+] citoplasmatico esta garantizada por la participacion de tres organelos: la mitocondria gigante unica, que representa el 12 % del volumen total, el acidocalcisoma--un organelo acidico dedicado a la acumulacion de pirofosfatos e involucrado en la bioenergetica del parasito- y el reticulo endoplasmatico (5).
