氧气运输系统只需铁原子便可运行,但血色素提供的蛋白质“笼状”结构能够大大提高其效率。
An oxygen transport system is possible with just the iron atoms, but it is very much more effective with the protein "cage" the structure of hemoglobin provides.

Figure 4 offers a visual look at the protein hemoglobin (image is a stereo pair; see Resources for the image source).
铁在能量的新陈代谢有重要的作用,是血色素组成的必需成分。能把血液里的蛋白质转化成氧。
Iron plays a key role in energy metabolism and is a necessary component of hemoglobin, the protein that transports oxygen in the blood.
