Entry term(s) contracción mitocondrial
mitocondria
Scope note: Organelas semiautónomas que se reproducen por sí mismas y se presentan en el citoplasma de la mayoría de las células eucariotas, pero no en todas. Cada una está rodeada por una doble membrana limítrofe. La membrana interna presenta múltiples invaginaciones y sus proyecciones se denominan crestas. La mitocondria es el lugar de las reacciones de fosforilación oxidativa que dan lugar a la formación de ATP. Contienen RIBOSOMAS, varios ARN DE TRANSFERENCIA, SINTETASAS AMINOACIL-ARN T y factores de elongación y terminación. Las mitocondrias dependen de los genes del núcleo, de las células en que residen, para muchos ARN MENSAJEROS. Se cree que las mitocondrias se han originado a partir de bacterias aerobiass que establecieron una relación simbiótica con los protoeucariotas primitivos.

Scope note: Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes. (King & Stansfield, A Dictionary of Genetics, 4th ed)
