Light āhua ahotakakame wāhanga o te tukanga

Ahotakakame rite te āhuatanga matū ko te tukanga i roto i nei ngā pūhui matū waro e hanga e mā te tauhohe i te wai, me te hauhā. He huru faufaa ko e te rere tukanga o te marama, me te whai wāhi tika o te matū photosynthetic. Hoki otaota taua matū he chlorophyll, huakita - bacteriochlorophyll.

Tenei tauhohenga Ko e tona āhua he maha-wā, me te āhua aronui. whakakitea Multistage i te meka e i roto i te ahotakakame tukanga anoo raupapa te fariiraa, tahuri, ka whakamahi i te aronui riro o pūngao marama. Ko tētahi taua hurihanga ko te huringa o te hauhā ki te mea organic. He tukanga i roto i nei i reira he mana nui me te pūhui rāpoi ngota ATP i huaina wāhanga marama o te ahotakakame. Ko te take huru matua me te rere o tenei wāhanga ko te aroaro o te pūngao marama. Ka taea te schematically māngai te tikanga mō te whakarite i tēnei hurihanga rite te wāhanga marama o te ahotakakame e whai ake. Chlorophyll, kei nei i runga i te kiriuhi i te chloroplasts o ngā tipu, absorbs te fluxes marama o te pūngao kōmaru. Na, whai wāhi tenei pūngao huānga hononga waikawa phosphoric ki ngā āhuatanga o ngā rāpoi ngota ATP me ADP. Heoi, i runga i tenei mahi pūngao marama e kore e mutu. I tua atu i te rongo ki rāpoi tukanga hononga, tenei pūngao āhei ki te kawe i roto i te tauhohe o ngā huānga wāwāhi wai. Here, te wāhanga marama o te ahotakakame rere i roto i te tauhohenga 2H20 = 4H + + 4e- + O2. I taea te kite i te hua o tenei tauhohenga, tavini hāora tipu A e ka tomo te puka noa i roto i te taiao māori.

Te taahiraa i muri mai, i roto i nei te kitenga i te wāhanga marama o te ahotakakame, ko te faaitoitoraa o ngā rāpoi ngota chlorophyll. I roto i tenei tukanga, i raro i te mana o te marama rāpoi ngota quanta chlorophyll te nekehanga irahiko ki te teitei te taumata irahiko i roto i te hanganga rāpoi ngota. Kaiwhakakökï me kawe irahiko e ko nga āhuatanga o te pūmua pūkano tipumata. E haere ana i te raupapa pūmua kawe raraunga, chlorophyll muingota takoha te irahiko e ki te ngaro tona pūngao, me te whakapaua ki runga ki te tiaki o te tukanga, pitihāoratanga o ngā rāpoi ngota ATP.

Ko te kupu ngaro tona pūngao me huānga (irahiko), kua whakahokia chlorophyll rāpoi ngota i te tua o ngā irahiko i nga te hua o te rere whakahuatia kua runga ake wāhinga tauhohe o ngā rāpoi ngota wai. synthesized hauwai I hanga i roto i te tukanga o te wāhinga te ki tetahi atu taonga i te mea nehenehe o te raveraa i tona ara nekeneke tūranga i roto i te pūkano tipumata.

te tīariari noatia Plants i roto i ngā āhuatanga pouri, i.e. ka wātea te rere o te pūngao marama. Na reira, e ahotakakame wahi, me te pouri taahiraa, kawea nei i roto i roto i te wāhi e takoto ana i waenganui i te casing me nga thylakoids pūkano tipumata. e kore hoki tenei wāhanga o te pūngao marama kua hiahiatia, me te tauhohe ano ngā o te raupapa o ngā tukanga o te huringa o ngā rāpoi ngota hauhā tomo ratou rangi. Ko te hua o taua panoni protrudes hanganga o ngā rāpoi ngota kūhuka, rawa me ētahi atu ngā pūhui matū waro. Taua pūhui ngā waikawa amino, nucleotides, me te nonireka mohiotia katoa.

I tua atu ki te wehenga ahotakakame wā, whakarōpū whakaaro i roto i te pūtaiao tenei tukanga māori i te momo. Ko te hunga matua ko C3 ahotakakame, ko C4 te ahotakakame, e hua, aua, a toru o wha-pūhui.
