摘要： 线粒体在能量代谢的过程中,除一部分能量用于合成ATP外,其余的以热的形式散发出来(代谢热).用精密的热量计测出线粒体代谢过程中热量输出,对了解线粒体能量代谢与机能具有十分重要的意义.

Abstract: The thermogenesis curves of mitochondria isolated from fish liver tissue were determined by using an LKB-2277 bioactivity monitor. After isolation from fish liver,mitochondria still has activity and can live for a long time by utilyzing the stored nutrients. We calculated the recovery rate constants of mitochondria and found that the thermogenesis curves of mitochondria are similar to those obtained from procaryotic cells. It was found by studying the thermogenesis curves that if a fish is superior in breed or grow faster than another, the stagnant period of mitochondria metabolism will be shorter and the recovery rate constant will be bigger.

Key words: fish liver, mitochondria, microcalorimetry, thermochemistry
