Sib cais dej hauv photosynthesis tshwm sim los ntawm qhov kev txiav txim ntawm Lub Teeb thiab cov txheej txheem no yog hu ua Photolysis ntawm dej lub lysis ntawm dej molecules uas tshwm sim nyob rau hauv zus tau tej cov hydrogen thiab oxygen nyob rau hauv chloroplast nyob rau hauv lub xub ntiag ntawm lub teeb hu ua photolysis. Nws kuj yog hu ua photo-oxidation ntawm dej.

Xav txog qhov no, dab tsi yog qhov sib cais ntawm cov dej thaum lub sijhawm photosynthesis?

Kev faib dej yog cov tshuaj tiv thaiv 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.

Ib yam li ntawd, 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 pa roj carbon dioxide.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qhov sib cais ntawm cov dej siv lub teeb lub zog hu ua?

Nyob rau hauv ib tug txheej txheem hu ua photolysis (' teeb 'thiab' cais '), lub teeb zog thiab catalysts cuam tshuam los tsav lub kev faib dej molecules rau hauv protons (H+), electrons, thiab oxygen gas.

Dab tsi enzyme zom cov dej hauv photosynthesis?

Cov enzyme uas pab txhawb cov tshuaj tiv thaiv no thiab yog li txhawb nqa txhua lub neej hauv peb lub ntiaj teb yog hu ua photosystem II (PSII), ib qho khoom siv ntau. enzyme embedded nyob rau hauv lipid ib puag ncig ntawm thylakoid daim nyias nyias ntawm cov nroj tsuag, algae, thiab cyanobacteria.
