Ahotakakame i roto i ngā tipu me ona āhuatanga

whakatokia ahotakakame Ko te tukanga tinana-matüora matatini e e tahuri tipu pūngao hiko, i te mea i roto i te hihi solar ki pūngao matū e whakamahia ana i roto i ngā pūhui matū waro. Ko te pūtake o tenei tukanga ko te tauhohenga matū mekameka, pitihāoratanga, rite ki te hua o nei e whakawhiti irahiko i te kaihoko kaituku-whakaiti, i te hauwai, me te wai, ki te acceptor, ko te āpitihāora. I roto i tenei puka warowaihā me tukua O2 te i roto i te piti hāora o te wai.

E rua kaupae karapīpiti ahotakakame whakato. huaina te wāhanga tuatahi ko te marama (ahomatū). I tenei wā, kua tahuri te pūngao marama aronui ki pūngao matū mō hononga pūhui tiketike-pūngao, me te he hāora ao. I roto i te taahiraa tuarua, he te ingoa pouri (pūkoro) whiwhi i te pūngao matū o te kaihoko whakaiti me te koropiko haere te ao mō te warea me te whakaiti o te hauhā, ai warowaihā e hanga e. photosynthetic tikanga wehe marama me te pouri taahiraa i roto i te wa e kore anake, engari ano hoki i roto i te wāhi. atamira marama e wahi i roto i te faafariuraa pūngao kiriuhi thylakoid motuhake, i te tauhohe pouri tango wahi rānei i te stroma pūkano tipumata, i roto i te cytoplasm ranei.

Ahotakakame me te whakato respiration hāngai te i runga i te absorption o quanta marama, i reira te whakatangihanga a te tūranga matua e chlorophyll tūāwhiorangi absorption e ngā te rohe kitea, me proximal tukunga wahi pōkākā me rohe katinga. Ko te ngarahu matua mō ngā otaota katoa ki te kawe i roto i te ahotakakame he chlorophyll he. pükohu Green, Kiwa me otaota iaia he ake me chlorophyll b, e whakawhānui ana te tūāwhiorangi o te marama whenumi. Ētahi momo o ngä pükohu i roto i chlorophyll c me d. I tua atu ki te chlorophyll, i te tukanga o te absorption marama e hoki carotenoids wāhi me phycobilins.

I muri i absorption o te marama puta taahiraa ahomatū i roto i nei e whai wāhi e rua ngā momo o te photosystem ahau me II (PS1 me PS2). Kei roto i ia o ApS o te pokapū tauhohe, ai puta tiaki wehenga, mekameka waka hiko, te wahi i te hāora irahiko, me te huinga o nga wāhanga e mahi nga tukanga o photooxidation o te wai, me te mahi whakaora i o te pokapū tauhohenga. I roto i te pokapū tauhohenga o te pūngao quantum marama e tahuri ki matū, a ka neke nga irahiko rite ki te rōnaki o te pūmanawa iahiko, e whakatu te mekameka irahiko waka o te ahotakakame.

Photosystem II momo mahi photooxidation tauhohe o te wai, reira hanga hāora me iraoho H +. e whakarara tukanga irahiko waka photosynthetic wahi whakawhitinga iraoho i te pūkano tipumata ki rohe intrathylakoid. Ko te tauhohe hua hua NADPH me ATP, e ko te hua tuatahi o te ahotakakame. I tua atu i te ahotakakame o te tipu te tikanga te tauhohenga enzymatic i roto i nei hauhā whiwhi i te pūmua, te warowaihā me te ngako. Ki te he directivity, te waikawa amino i hanga, te pākia kore-warowaihā pouri matū me pūmua.

E wehea tukanga pūkoro tinana mō te momo CO2 warea ki C3, C4 me CAM ahotakakame. Ko te kupu kia takoto warowaihā, e kua hanga e runga i te atamira pouri o te ahotakakame i chloroplasts i te puka o pūhui māngaro putanga te pūkano tipumata ki te hanga i ngā pūtau hou ki te mahi rite te puna o te pūngao mō ngā tauhohe pūkoro.

whakamahi tipu ahotakakame 1-2 anake ōrau o te pūngao marama whenumi. Ko te kaha o te tukanga o te ahotakakame pānga te hanganga spectral me te kaha o te marama, te pāmahana, otaota maimoatanga wai me te kohuke kai tōtika, te kukū o te CO2 me O2, me ētahi atu āhuatanga taiao.
