问题 PASSAGE FOUR [br] How do the abnormal chemical bonds form?
选项
答案 Free radicals produced from iron interact with the organic tissue．
解析 根据题干中的abnormal chemical bonds定位至第八段第一句Dr．Schweitzer and Dr．Goodwin believemat highly reactive ions known as free radicals，which ale produced by iron as it is released from thehaemoglobin．interact with the organic tissue causing abnormal chemical bonds to form．由定位句可知，血红蛋白中释放的离子叫作游离基，这种游离基与有机组织结合产生了这种异常化学键，故答案为Freeradicals produced from iron interact with the organic tissue。
