6. In virtually all types of issue in every animal species, dioxin induces the production of enzymes that are the organism's trying to metabolize, or render harmless, the chemical that is irrtating it.
(E) attempt to metabolize, or render harmless, the chemical irritant
这个选项是正确选项,我想问一下此处关于逗号的作用
第一个逗号是不是因为在平行结构中前面的结构复杂,所以在连词or前加了逗号
第二个逗号我不太理解,是不是the chemical irritant 是 metabolize和render的共同宾语,加逗号是因为the chemical irritant 前有个the,无法与前面的render harmless连接呢?
G友们的帮助
我的理解
事实上在每种生物的器官中,d刺激了在组织中的e去新陈代谢、或代表无害的产生,一种化学成分刺激物。
the chemical 是d的同位语,修饰d
