Cov chlorophyll molecule tshuav tsis muaj hluav taws xob coj uas electron dej sib cais tus dej nyob rau hauv hydrogen ions thiab oxygen gas. Qhov no yog vim li cas photosynthesis tso pa oxygen rau hauv huab cua. Lub ntsiab lus ntawm lub teeb pom kev yog ua kom muaj ntau ntawm NADPH thiab ATP.

Hauv qhov no, yuav ua li cas yog tias tsis muaj kev sib cais ntawm cov dej hauv photosynthesis?

Thaum dej molecules cais thaum cov photosynthetic cov tshuaj tiv thaiv, oxygen molecules yog tsim thiab tso rau hauv dej thiab huab cua. Tsis muaj oxygen, lub neej yuav tsis muaj li nws ua hnub no. Ntxiv mus, photosynthesis plays lub luag haujlwm tseem ceeb hauv kev tso cov pa roj carbon dioxide.

Qhov thib ob, ua li cas h2o phua hauv photosynthesis? Kev faib dej yog cov tshuaj tiv thaiv nyob rau hauv uas dej yog tawg rau hauv oxygen thiab hydrogen: 2 H2O → 2 H2 + O. Ib version of dej sib cais tshwm sim hauv photosynthesis , tab sis hydrogen tsis tsim. Qhov rov qab ntawm dej sib cais yog lub hauv paus ntawm hydrogen roj cell.

Kuj tseem yuav paub, yuav ua li cas thaum dej sib cais hauv photosynthesis?

Thaum lub teeb tshwm sim ntawm Photosynthesis , chlorophyll yuav qhib los ntawm lub teeb. Qhov no lub teeb activated chlorophyll yuav cais tus dej molecule. Cov txheej txheem no hu ua Photolysis. Dej molecule yog cais tso H + ions thiab oxygen.

Vim li cas qhov kev sib cais ntawm cov dej tseem ceeb hauv cov teeb pom kev zoo?

Hydrogen atoms, electrons, thiab oxygen. Piav vim li cas cov kev faib dej yog tseem ceeb mus rau qhov txuas ntxiv ntawm teeb pom kev zoo . Nws tseem ceeb vim rau txhua ob molecules ntawm dej uas yog cais , plaub lub tshuab hluav taws xob muaj los hloov cov uas ploj los ntawm chlorophyll molecules hauv photosystem II.
