1F：→ Alconox:ADA(我的答案..) 02/03 01:18
2F：→ cornere:我觉得是AEA耶... 02/04 20:10
3F：推 zphiroude:我觉得是ADD，3.酵素应该会增加催化速度，Vman不变吧 02/10 21:44
4F：推 demon123:我也觉得是ADD耶 02/12 22:31
6F：→ momofishj:里面有提到: Vmax is directly proportional to the 03/05 13:17
7F：→ momofishj: total enzyme concentration, E, and the catalytic 03/05 13:17
8F：→ momofishj:of the enzyme, kcat 03/05 13:17
9F：→ momofishj:所以我想第三题应该是A吧~ 03/05 13:18
