Metabolism isn't about the digestion of food in your stomach; it's the name given to all of the chemical changes that occur in an organism's tissue cells.

新陈代谢不是指食物的消化能力，而是指一种在组织细胞内发生的化学变化。

After all, it's a tough job - you Labour unnoticed in the lab, your family has no idea what you do, then one day your name appears in print and you have something you can show your mum.

毕竟，这是个苦差事。你在实验室里默默无闻埋头苦干，家人对你的工作一无所知；然后，有一天你的大名出现在报纸杂志上，总算能有点东西让咱妈开开眼。
