Light nooca wajiga photosynthesis ee geedi socodka

Photosynthesis sida Ifafaale kiimikada waa hab kaas oo xeryahooda organic waxaa la aasaasay by ficil biyaha iyo carbon dioxide. Xaalad muhiim ah waa in socodka geedi socodka iftiinka, iyadoo ku lug toos ah oo ka mid ah walxaha photosynthetic. Waayo, flora walxaha kale waa chlorophyll, bakteeriyada - bacteriochlorophyll.

reaction Kani waa dabeecada waa multi-yada iyo nooca galmada. Multistage muujiyey in xaqiiqda ah in inta lagu guda jiro photosynthesis habka dhici sequentially qaata, diinta, iyo sida loo isticmaalo galmada helay tamarta iftiinka. Mid ka mid ah isbadal sida waa isbeddel ah ee carbon dioxide galay arrinta organic. nidaamka A kaas oo waxaa jira awood sare oo xeryahooda Britain ATP yeedhay wajiga light of photosynthesis. The factor xaalad muhiimsan iyo socodka marxaladda ay tani tahay joogitaanka tamarta iftiinka. farsamo ee hubinta Isbadal sida wajiga light of photosynthesis la schematically wakiil karaa sida soo socota. Chlorophyll, oo ku yaalla on xuubka ee chloroplasts dhirta, nuuga ah fluxes light of tamarta qorraxda. Markaas, tamarta this kordhinaya xubno xidhiidh acid phosphoric la xubno ka taagoo ATP iyo ADP. Si kastaba ha ahaatee, on this shaqo tamarta iftiinka dhamaanin. ka-gaadhista taagoo isuga habka reebo, tamarta this awood si ay u fuliyaan falcelinta ee xubno qaybsama biyaha. Halkan, wajiga light of photosynthesis qubanayo in fal-celinta 2H20 = 4H + + + 4e- O2. Sida laga arki karo, natiijada cadaanyo this adeegta oxygen waxaad fartaan Wannaagga taas oo ka dibna galo qaab xor ah ee deegaanka dabiiciga ah.

Tallaabada xigta, taas oo ogaaday wajiga light of photosynthesis, waa hawshooda u ah ee u taagoo chlorophyll. Inta lagu jiro habkan, sarkhaansan Britain chlorophyll quanta nuurka guuro electron si sare heerka electron in qaab dhismeedka Britain. Xoojiya iyo sidayaal electron in ay yihiin xubno ka mid ah borotiinka chloroplast ah. Isagoo maraya a borotiinada side xogta isku xigxiga, Britain chlorophyll electron waxaa lagu qasbay in laga badiyo ay tamar, oo waxaa la bixisay on dayactirka ah ee geedi socodka redox ee u taagoo ATP ah.

Sayidka badiyay tamarta iyo xubno (electrons), Britain chlorophyll soo celiyay by dheer ee electrons ay ahaayeen natiijada socodka hore u soo sheegnay kor reaction cholesterol ee u taagoo biyo. hydrogen-dhafka ah ee geedi socodka of cholesterol uu ku dhexsameeysmo la walax kale taas oo ah awood ugu leeyihiin qabashada ay conveyor doorka gudahood chloroplast ah.

Geedaha si dabiici ah ka jiraan xaalado mugdi ah, i.e. marka socodka tamarta iftiinka heli karaa. Sidaa darteed, photosynthesis qaadataa meel mugdi ah oo tallaabo, oo waa la fuliyay in meel bannaan oo been u dhexeeya sanduuqa battariga iyo thylakoids chloroplast ah. Waayo, wajiga this tamarta iftiinka looma baahna, iyo dareen-celin laftiisa ka kooban yahay isku xigxiga oo ka mid ah geedi socodka of Isbadal ee u taagoo carbon dioxide galaya ay hawada. Natiijada transformations sida ay laftu formation of taagoo glucose, gaar ahaan iyo xarumaha kale ee dabiiciga ah. xeryahooda noocan oo kale ah waxaa ka mid ah acids amino, nucleotides, iyo sidoo kale dhammaan glycerol yaqaan.

Waxa intaa dheer in separation wajiga photosynthesis, kala soocidda loo arkaa in sayniska nidaamka dabiiciga this by nooc. Oo ah kuwa ugu muhiimsan yihiin photosynthesis C3, iyo C4 photosynthesis, kaas oo ay soo saaraan, siday u kala horreeyaan, iyo saddex ka mid ah afarta xarunta.
