Atrazine inhibits photosynthesis los ntawm kev sib tw nrog plastoquinone B (QB) khi qhov chaw ntawm D1 subunit ntawm PSII , thiab yog li thaiv chloroplast electron ntws los ntawm plastoquinone A mus rau QB, , txo qis ntau lawm ntawm ATP, nicotinamide adenine dinucleotide phosphate nicotinamide adenine dinucleotide phosphate Hauv kev sib piv, NADP + / NADPH piv yog ib txwm txog 0.005, yog li NADPH yog daim ntawv tseem ceeb ntawm cov coenzyme no. Cov kev sib txawv no yog qhov tseem ceeb rau lub luag haujlwm sib txawv ntawm NADH thiab NADPH. https://en.wikipedia.org › Nicotinamide_adenine_dinucleotide

Atrazine cuam tshuam li cas rau ob feem ntawm photosynthesis?
Atrazine tua cov nroj tsuag los ntawm cuam tshuam photosynthesis. Photosynthesis - tshwj xeeb rau ntsuab, cov nroj tsuag muaj sia nyob - tshwm sim thaum lub teeb lub zog hloov mus rau lub zog tshuaj uas xav tau rau kev tsim khoom noj. Tsuas yog hais tias, thaum cov zaub mov nres, cov nroj tsuag thaum kawg tshaib plab tuag.
Atrazine ua li cas nres cov nroj tsuag kev loj hlob?
Atrazine yog tshuaj tua kab mob uas tiv thaiv kev loj hlob ntawm cov nroj tsuag by inhibiting photosynthesis. Atrazine ua hauj lwm los ntawm kev khi rau cov proteins nyob rau hauv lub electron thauj saw ntawm photosystem II. Thaum atrazine khi rau cov proteins, cov hluav taws xob tsis tuaj yeem taug kev hauv cov saw hlau mus txog photosystemI.
atrazine cuam tshuam li cas rau photosystem 2?
Atrazine thiab bentazon yog ob qho tib si photosystem-II (PSII)–inhibiting herbicides uas cuam tshuam nrog photosynthetic electron thauj, provoking oxidative stress. Thaum atrazine ua rau kom taum pauv [Glycine max (L.) … Soybean cog 48 teev tom qab siv bentazone. Cov nplooj tshiab trifoliate loj hlob ib txwm.
Lub xub ntiag ntawm atrazine cuam tshuam li cas rau lub peev xwm ntawm chloroplasts rau photosynthesize?
… Atrazine khi rau D1 protein thiab thaiv kev khi ntawm plastoquinone (PQ). Los ntawm inhibiting qhov khi ntawm PQ, cov txheej txheem ntawm photosynthetic electron hloov pauv tau cuam tshuam, thiab cov synthesis ntawm ATP thiab NADPH hauv chloroplast raug cuam tshuam (Bai li al., 2015).
