线粒体是生物能量的热点,通过氧化磷酸化过程产生大量的ATP。线粒体在结构上也是动态的,并经历协调的融合和分裂以维持其功能。最近对线粒体(融合机制)的研究为详细说明它们在线粒体新陈代谢中的作用提供了新的证据。值得注意的是,丝裂原2,除了它在融合中的作用外,对维持辅酶Q水平也是重要的,并且可能是甲氧丙酮酸合成途径中的一个不可或缺的角色。在这里,我们回顾了线粒体动力学的生物能量学作用,并强调了在评估线粒体呼吸时体外生长条件的重要性。本文是由Paolo Bernardi教授编辑的题为《EBEC 2016:第19届欧洲生物能量学会议,意大利里瓦德尔加尔达,2016年7月2日至6日》特刊的一部分。(C)2016年,由爱思唯尔出版。
Mitochondria are bioenergetic hotspots, producing the bulk of ATP by the oxidative phosphorylation process. Mitochondria are also structurally dynamic and undergo coordinated fusion and fission to maintain their function. Recent studies of the mitochondria( fusion machinery have provided new evidence in detailing their role in mitochondrial metabolism. Remarkably, mitofusin 2, in addition to its role in fusion, is important for maintaining coenzyme Q levels and may be an integral player in the mevalonate synthesis pathway. Here, we review the bioenergetic roles of mitochondrial dynamics and emphasize the importance of the in vitro growth conditions when evaluating mitochondrial respiration.
