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.

Muaj pes tsawg ATP tsim nyob rau hauv citric acid voj voog?
Hauv eukaryotes, lub voj voog Krebs siv cov molecule ntawm acetyl CoA los tsim 1 ATP, 3 NADH, 1 FADH2, 2 CO2, thiab 3 H +. Ob lub molecules ntawm acetyl CoA yog tsim nyob rau hauv glycolysis yog li tag nrho cov molecules tsim nyob rau hauv lub citric acid voj voog yog ob npaug (2 ATP, 6 NADH, 2 FADH2, 4 CO2, thiab 6 H +)
Muaj pes tsawg tus txiv neej tsim cov ntsiab lus muaj nyob rau hauv lub rooj zaum?
Cov khoom siv hluavtaws yog cov uas muaj atomic tooj 95-118, raws li pom hauv ntshav ntawm lub rooj sib tham nrog: cov 24 lub ntsiab lus no tau tsim thawj zaug thaum xyoo 1944 thiab 2010
Muaj pes tsawg qhov kev zam rau tus qauv electron configurations muaj nyob rau hauv D block?
ob Ntawm no, cov ntsiab lus twg yog kev zam rau Aufbau txoj cai? Piv txwv li, ruthenium, rhodium, nyiaj thiab platinum yog tag nrho kev zam rau Aufbau txoj cai vim yog sau los yog ib nrab puv subshells. Ib sab saum toj no, yog vim li cas electron configuration rau tooj liab 1s22s22p63s23p63d104s1 es tsis txhob 1s22s22p63s23p63d94s2?
Muaj pes tsawg ATP raug tsim nyob rau hauv acetyl CoA tsim?
Txhua acetyl-CoA yields 3 NADH + 1 FADH2 + 1 GTP (= ATP) thaum lub sij hawm Krebs. Xav txog qhov nruab nrab ntawm 3 ATP / NADH thiab 2 ATP / FADH2 siv cov saw ua pa, koj muaj 131 ATP molecules
Muaj pes tsawg txoj hauv kev genetic recombination muaj nyob rau hauv cov kab mob?
Muaj peb txoj hauv kev tseem ceeb uas genetic recombination tshwm sim hauv cov kab mob, thawj qhov hu ua transformation. Qhov no yog thaum ib daim DNA pub dawb los ntawm tus neeg tau txais kab mob
