Cov oxygen tso tawm thaum photosynthesis los los ntawm kev sib cais ntawm cov dej thaum lub teeb-dependent cov tshuaj tiv thaiv. 3. Nco ntsoov, cov electrons poob los ntawm qhov chaw tshuaj tiv thaiv hauv photosystem II yuav tsum tau hloov.

Yog li ntawd, qhov twg oxygen tso tawm hauv photosynthesis?

Cov oxygen thaum photosynthesis los ntawm kev sib cais dej molecules. Thaum photosynthesis , cov nroj tsuag absorbs dej thiab carbon dioxide. Tom qab kev nqus, cov dej molecules yog disassembled thiab hloov mus rau hauv qab zib thiab oxygen.

Tsis tas li ntawd, dab tsi yog lub hauv paus ntawm oxygen tso rau hauv cov huab cua raws li cov khoom ntawm photosynthesis? Photosynthesis siv carbon dioxide thiab dej kom sib sau cov carbohydrate molecules (feem ntau qabzib ) thiab tso pa oxygen rau saum huab cua.

Ib tug kuj yuav nug, qhov twg cov pa oxygen hauv cov nroj tsuag tuaj ntawm?

Feem ntau ntawm no oxygen los ntawm me dej hiav txwv nroj tsuag - hu ua phytoplankton - uas nyob ze ntawm dej saum npoo av thiab ntws nrog cov dej ntws. Zoo li tag nrho nroj tsuag , lawv photosynthesize - uas yog, lawv siv hnub ci thiab carbon dioxide los ua zaub mov. Ib tug byproduct ntawm photosynthesis yog oxygen.

Dab tsi yog 3 theem ntawm photosynthesis?

Nws yog qhov yooj yim los faib cov photosynthetic txheej txheem hauv cov nroj tsuag ua plaub theem , txhua qhov tshwm sim nyob rau hauv ib cheeb tsam ntawm chloroplast: (1) nqus ntawm lub teeb, (2) electron thauj mus rau qhov txo ntawm NADP+ rau NADPH, ( 3 ) tiam ntawm ATP, thiab (4) kev hloov pauv ntawm CO2 nyob rau hauv carbohydrates (carbon fixation).
