Hauv cyclic photophosphorylation 2 ATP molecules yog ua.

Tib neeg kuj nug, ATP ua li cas thaum lub sij hawm cyclic Photophosphorylation?

Cyclic photophosphorylation Qhov no thauj saw tsim tawm proton-motive quab yuam, twj H+ ions hla lub membrane; qhov no tsim tawm ib tug concentration gradient uas yuav siv tau rau lub hwj chim ATP synthase thaum chemiosmosis. Txoj kev no hu ua cyclic photophosphorylation , thiab nws tsim tawm tsis yog O2 los yog NADPH.

Dab tsi yog cov khoom kawg ntawm cyclic Photophosphorylation? Nyob rau hauv tej yam kev mob, lub photoexcited electrons coj lwm txoj kev hu ua cyclic electron flow, uas siv photosystem I (P700) tab sis tsis photosystem II (P680). Cov txheej txheem no tsim tsis muaj NADPH thiab tsis muaj O2, tab sis nws ua ATP. Qhov no hu ua cyclic photophosphorylation.

Ua kom pom qhov no, ntau npaum li cas ATP raug tsim hauv photosynthesis?

Thaum photosynthesis 18 molecules ua ATP yog siv rau hauv cov nroj tsuag c3. Tawm ntawm 12 no yog siv rau hauv kev sib txuas ntawm 1 qabzib molecule thiab 6 rau kev rov tsim dua ntawm RUBP.

Muaj pes tsawg ATP raug tsim nyob rau hauv lub teeb nyob rau hauv cov kev tshwm sim?

Cov teeb - raws li kev xav hloov teeb lub zog rau hauv chemical zog, tsim ATP thiab NADPH. 5. Cov teeb - raws li kev xav tuaj yeem sau tau raws li hauv qab no: 12 H2O + 12 NPE+ + 18 ADP + 18 Pi + teeb thiab chlorophyll yields 6 O2 +12 NPE + 18 ATP.
