Nyob rau hauv cyclic photophosphorylation, cov electrons rov qab los rau chloroplast molecules, thaum nyob rau hauv lub non-cyclic photophosphorylation, kev sib cais ntawm dej muab cov electrons rau chloroplast thiab tsim oxygen raws li los ntawm khoom. Hauv non-ncyclic photophosphorylation tsim NADPH thiab ATP.
oxygen tsim thaum lub sijhawm photosynthesis tuaj qhov twg?
Cov pa tawm thaum lub sijhawm photosynthesis yog los ntawm dej. Cov nroj tsuag yuav nqus dej thiab carbon dioxide thaum lub sijhawm photosynthesis. Tom qab ntawd cov dej molecules hloov mus rau oxygen thiab qab zib. Tom qab ntawd cov pa oxygen tso rau hauv qhov chaw thaum cov piam thaj molecules khaws cia rau lub zog.
YPuas yog oxygen tsim nyob rau hauv cyclic Photophosphorylation?
Photophosphorylation tshwm sim ntawm stroma lamella lossis frets. Hauv cyclic photophosphorylation, lub zog hluav taws xob siab yog pub dawb los ntawm P700 mus rau ps1 ntws mus rau txoj hauv kev cyclic. … Txoj hauv kev no raug txheeb xyuas tias yog cyclic photophosphorylation, thiab nws tsis tsim cov pa oxygen (O2) lossisNADPH.
YYuav ua li cas thaum lub sijhawm Photophosphorylation?
Photophosphorylation yog kev hloov pauv ntawm ADP rau ATP siv lub zog ntawm lub hnub ci los ntawm kev ua kom PSII . Qhov no suav nrog kev sib cais ntawm cov dej molecule hauv oxygen thiab hydrogen protons (H+), txheej txheem hu ua photolysis. Tom qab ntawd, txuas ntxiv unidirectional ntws ntawm electron los ntawm dej mus rau PSI yogua tau (Fig.
Yuav ua li cas cov pa roj O2 yog tsim thaum lub sij hawm photosynthesis?
Thaum lub teeb pom kev zoo, ib qho hluav taws xob raug rho tawm ntawm cov dej molecule tso cov pa oxygen thiab hydrogen atoms. Lub atom dawb oxygen ua ke nrog lwm cov pa dawb oxygen atom los tsim cov pa oxygen uas tau tso tawm.

Thaum lub sijhawm tawg ntawm hemoglobin lub bilirubin yog tsim los ntawm?
Kev tsim ntawm Bilirubin Kwv yees, 80% ntawm bilirubin yog tsim los ntawm kev tawg ntawm hemoglobin hauv senescent cov qe ntshav liab, thiab ua kom puas erythroid hlwb hauv pob txha pob txha. Cov seem yog tshwm sim los ntawm kev hloov pauv ntawm ntau yam heme-muaj protein ntau pom nyob rau hauv lwm cov ntaub so ntswg, feem ntau ntawm daim siab thiab cov leeg.
Thaum lub sijhawm ua pa ntawm tes uas ntawm cov hauv qab no tso tawm los ntawm cov khoom lag luam?
Thaum lub sijhawm ua pa aerobic cellular, qabzib reacts nrog oxygen, tsim ATP uas tuaj yeem siv los ntawm tes. carbon dioxide thiab dej yog tsim los ntawm cov khoom lag luam. Hauv kev ua pa ntawm tes, qabzib thiab oxygen hnov qab tsim ATP.
Lub sijhawm kuv lub sijhawm dawb lossis thaum kuv lub sijhawm dawb?
yog li, qhov no txhais tau tias "thaum kuv lub sijhawm dawb" tsis siv ntauthiab koj muab "hauv kuv lub sijhawm dawb" ntau dua nyob rau qhov kawg ntawm kab lus. Piv txwv li: Kuv tau taug kev tus dev thaum kuv lub sijhawm dawb.
Lub sijhawm nyob qhov twg ntawm lub sijhawm teem sijhawm?
kab kab rov tav ntawm lub rooj ntu ntu yog hu ua ntu ntu. Lub sijhawm nyob rau ntawm lub sijhawm nyob qhov twg? Ib lub sijhawm yog kab kab rov tav ntawm lub rooj ntu ntu. Muaj xya lub sij hawm nyob rau hauv lub sij hawm ntawm lub sij hawm, nrog txhua tus pib ntawm sab laug.
Lub sijhawm photosynthesis oxygen yog hloov zuj zus los ntawm dej los ntawm kev pab?
Cov txheej txheem photosynthesis cuam tshuam nrog kev tawg ntawm cov dej molecules rau hauv hydrogen thiab oxygen nyob rau hauv lub hnub ci yog hu ua photolysisntawm dej. Muaj ntau cov as-ham koom nrog hauv cov tshuaj tiv thaiv zoo li chlorine thiab manganese.
