- (Español)
解説
- 独自のゲノムをもち,重要な機能を担っている.ATP合成,プログラム細胞死,アミノ酸やヘム,ヌクレオチド,脂質の合成などで重要な役割を果たしている.
- ヒトの場合,約16.5k塩基対の二本鎖の環状DNAで,13個のタンパク質コードを含む37個の遺伝子をもつ.
- 進化的には約15-20億年前に起こった細胞内共生に由来する.
- 多細胞生物では,ミトコンドリアの機能不全は様々な影響をおよぼし,多くの場合障害をひきおこす.
Definition
Glossary of "Plant Biology (1st ed.)" by Graham et al. (2003)
- Organelles present in eukaryotic cells that are the location for the generation of energy in the form of ATP by the process of respiration.
Glossary of "Plant Systematics (1st ed.)" by Simpson (2006)
- A double membrane-bound, cellular organelle with invaginations called cristae that function in the electron transport reactions of respiration. Pl: mitochondria.
Glossary of "Life (9th ed.)" by Sadava et al. (2011)
- an organelle in eukaryotic cells that contains the enzymes of the citric acid cycle, the respiratory chain, and oxidative phosphorylation.
Glossary of "The Evolution of Plants (2nd ed.)" by Willis & McElwain (2014)
- Structures within the cytoplasm of plant cells that carry out aerobic respiration.
