What is Life? Artificial Photosynthesis(人工光合成)

Good morning everyone. Today, Sammy started the "What is Life?" by overcoming the trouble. Today's theme is about artificial photosynthesis.

皆様お早うございます。本日サミぃは問題を乗り越え、What is Life?をまた開始します。本日のテーマは「人工光合成」です。

Because we are animal, we have great problem about food. If the increase of number of people continue at least 10 years long, the foods war will be happened in the world. In such period, we will regret that we have no plan to resolve the problem. To avoid such future, some scientist groups has started the study about artificial photosynthesis.


All plants have chloroplasts to fix carbon dioxide for producing sugar from energy of sunshine. We learn the basis of plants having such capacity in elementary school. Because we are animal, most of us can not fix carbon dioxide by photosynthesis.


On the other hand, if we can digest plants in the stomach like cattle, we can survive in wild. Sammy thought such idea when I was a junior high school student. But the artificial photosynthesis may be better idea rather than it.


The famous novelist Dr. Negishi has started the approach about artificial photosynthesis as Chemist. As you may know, photosynthesis consists with many complex reactions. All reactions are performed with enzymatic power. Although Sammy doesn't know detail of his expectancy, perfect mimic of plants may be impossible. I think so, because I am a biologist. I can't believe that all enzyme of the reaction can be replaced with  catalysis. The whole of organism may not be so simple. 


But I want it. We don't need war again. We want to live, because we are life. Sammy wants to live with acknowledgement for others. Are you ready?


Today's class is over. Have a nice day. Click the button at the bottom of this "What is Life?", if you are a student of this class. Mind you? If you have any question about life, please send an e-mail for me.
