Cov cytochrome proteins hauv ETC muaj cov pab pawg heme uas koom nrog kev thauj khoom hluav taws xob. … Txawm li cas los xij, tsis zoo li cov pab pawg heme nyob rau hauv cov pa oxygen-binding proteins, lub heme hlau ntawm cytochromes yog reversibly txo thiab oxidized thaum lub sij hawm ETC kev ua.
Dab tsi yog qhov txo qis hauv cov saw hlau thauj hluav taws xob?
Electron thauj yog ib qho kev cuam tshuam redox uas zoo ib yam li kev sib tw sib tw lossis lub thoob hauv lub tshuab hluav taws xob hauv cov khoom siv hluav taws xob tau dhau los ntawm ib feem mus rau lwm qhov, mus rau qhov kawg ntawm cov saw hlau uas cov electrons txo molecular oxygen, tsim dej.
Puas yog cov saw hlau thauj hluav taws xob oxidized lossis txo?
Thaum electrons tuaj txog ntawm complex IV, lawv raug xa mus rau ib lub molecule ntawm oxygen. Txij li thaum cov pa oxygen tau txais electrons, nws raug txo kom dej. Thaum cov oxidation thiab txo qiskev tshwm sim tshwm sim, lwm qhov kev sib txuas tshwm sim tshwm sim hauv cov saw hlau thauj hluav taws xob.
Yuav siv hlau li cas hauv kev thauj khoom hluav taws xob?
Cov hlau atoms tam sim no nyob rau hauv pawg Fe-S tuaj yeem tshwm sim xws li ferric lossis ferrous hlau thiab lub voj voog ntawm lub xeev redox, tso cai rau Fe-S pawg koom nrog cov tshuaj tiv thaiv redox. … Fe-S pawg kho kom haum electron hloov pauv nyob rau hauv thiab nruab nrab ntawm cov pa ua pa ntawm cov saw hlau thauj electron [72, 73].
Dab tsi yog oxidized thiab txo hauv electron thauj saw?
ReactionsKev koom nrog kev hloov hluav taws xob yog hu ua oxidation-txo cov tshuaj tiv thaiv (lossis redox tshuaj tiv thaiv). Tej zaum koj yuav tau kawm nyob rau hauv chemistry hais tias ib tug redox cov tshuaj tiv thaiv yog thaum ib molecule poob electrons thiab yog oxidized, thaum lwm molecule tau txais electrons (tus uas poob los ntawm thawj molecule) thiab txo.

Thaum lub sijhawm tawg hluav taws xob hluav taws xob yog?
Volcanic eruptions tsim peb yam khoom: gas, lava, thiab fragmented khib nyiab hu ua tephra. Cov ntaub ntawv dab tsi siv rau hauv kev tawg hluav taws kub? ash, ciders, kub tawg, thiab cov foob pob pov tseghauv cov khoom tawg yog cov khoom loj uas tau pom nyob rau hauv volcanic eruptions thoob ntiaj teb.
Lub tshuab hluav taws xob twg siv rau kev tsheb ciav hlau hluav taws xob?
TE Connectivity's (TE) optimized VESA nqus Circuit Court breaker rau railway electrification yog thawj tag nrho electro-magnetically ua system rau 25 kV thiab 15kV tsheb. Lub tshuab hluav taws xob twg siv hauv kev tsheb ciav hlau? 2.
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Koj puas tuaj yeem tsim hluav taws xob xaim hluav taws xob?
Tsis txhob xaim hluav taws xob. Thiab, yog tias koj muaj lub siab xav ua hluav taws xob woven hlau - koj tuaj yeem xav txog kev txhim kho cov hlau kub kub rau nws kom cov tsiaj tawm ntawm nws. Koj puas tuaj yeem tsim hluav taws xob hluav taws xob?
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
