2F：推 tekkaman:D應該是BY CASE，但E一定是對的，至少有乙烯，題庫出來的 06/19 00:16
3F：→ tekkaman:動物激素未必較濃的原因是，他們可以用PROTEIN去帶 06/19 00:17
4F：→ tekkaman:再來個受體媒介內吞。 06/19 00:18
5F：→ orangerhana:但動物不是也有空氣傳播的？像是女生MC同時...等 06/19 00:19
6F：→ Leanovia:樓上指的是費洛蒙(pheromone)造成MC同步.但它不是hormone 06/19 01:08
7F：→ orangerhana:QQ............. 06/19 01:16
8F：推 smallerfat:E選項campbell上面有講，D選項應該是要考動物激素濃度 06/19 10:53
9F：→ smallerfat:很低也可以靠一些二級傳遞的放大反應(ex:cAMP)來作用 06/19 10:54
10F：→ smallerfat:所以濃度不一定要高於植物 06/19 10:54
