In our bodies, these kinds of reactions can’t and don’t take thousands of years to happen, because we have an enzyme called carbonic anhydrase that catalyzes that reaction.

我们体内，这类反应不会花费数千年时间来完成， 因我们有名碳酸酐的可以催化这个反应。

Carbonic anhydrase is an enzyme in the red blood cells that quickly converts carbon dioxide and water into bicarbonate and hydrogen ions.

碳酸酐是红细胞中的，能迅速将二氧化碳和水转化碳酸氢盐和氢离子。
