1F：推 Secondier:我覺得選CO2,因為是直接從glucose中分離出去的。 10/27 16:02
2F：推 senonno1:我記得A1題庫說的是給標定過的glucose吧??如果是這樣的話 10/28 22:17
3F：→ senonno1:兩個答案沒有衝突啊~ 10/28 22:18
4F：→ rubylll:可是A2的不是也是標定過的glucose嗎? 10/28 23:02
5F：推 daouz:CO2來自glucose H2O來自電子傳遞的 O + 2e- + 2H+ 10/28 23:23
6F：→ senonno1:抱歉我打錯= =A1上面那題應該是說標定過的O2答案才會是水 10/29 04:26
7F：→ senonno1:吧~ 10/29 04:27
