Last time we talked about photosynthesis, the process by which plants use light to convert carbondioxide and water into food.
上次我们讨论了光合作用，即植物利用光将二氧化碳和水转化为食物的过程。

Plants also convert carbondioxide into different forms of carbon-containing molecules and the conversion process used relies on the very same enzyme that works in humans.
植物也会将二氧化碳转化成不同形式的含碳分子，而转化过程所使用的酶与人体内的酶完全相同。

Some companies have commercialized a process that captures carbondioxide and converts it to solid material, but those efforts rely on a chemical process to capture carbondioxide.
