Cabbage Oven(Finally change the topic)

Hola(西班牙文)！After finishing the long and long introduction of gender chanching,we will get to explore  my favorite area of biology─Biochemistry,which use the viewpoint of chemistry to explain complex phenomena in biology.And this week,I will start this topic with a special kind of plant,which is called Eastern skunk cabbage(臭鼬包心菜).

(in the summer)

(in the early spring)

As its name said,it also like our first week's topic─Its flower had distinctive smell.However,Its ordor is not our focus this week.What we want to see is its heating ability when it blooms.It can heat up itself to 15~35°C while it is snowing.How incredible the plant is！How does it do that？Well,We will find the answer by using the knowledge of biochemistry.

Do you guys remember the mechanism(機制) of aerobic respiration(有氧呼吸) taught in senior high school?If you forgot it,you can try this vedio to recall it.

As you recall the memory,we can understand the magic that the skunk cabbage play.The skunk cabbage has two kinds of aerobic respiration.One is for generating ATP,and this kind of aerobic respiration is the normal one that we have learned.Another one is for generating heat.The steps of this type are a little bit different.Because its purpose is to generate heat,the structure to generate ATP is useless.So in the step “electron transcript chain”(電子傳遞鏈 簡稱ETC),there's no ATP synthase(ATP合成酶)in the terminal of ETC,which means the process EYC can only let electron running on it but cannot generate ATP.It is just like electron wire,whose electron energy “P=I平方R”will spread into the environment.And then,you got a view of cabbage oven！
At last,let's watch the real situation of this interesting oven.Thank you for your visiting！
