Vim li cas cov cab kuj xav tau rau kev thauj cov electrons Los ntawm ib feem ntawm chloroplast mus rau lwm qhov? Siab zog electrons txav mus los ntawm electron thauj saw hlau. Pigments hauv Photosystem II nqus lub teeb. ATP synthase tso cai rau H + ions dhau los ntawm thylakoid membrane.
Ntxiv mus, dab tsi ua rau ib tug zoo electron cab kuj?
Lawv txais tau electrons thiab hloov feem ntau ntawm lawv lub zog mus rau lwm lub molecule. Lawv yog cov molecules loj heev, yog li lawv muaj ntau chav rau nqa ntau electrons . Lawv tuaj yeem nqus tau lub hnub ci, uas yog qhov chaw tag nrho ntawm lub zog siab electrons los ntawm.
Ib yam li ntawd, dab tsi yog cov khoom siv hluav taws xob hauv cellular respiration? Muaj ob lub tshuab nqa hluav taws xob uas ua lub luag haujlwm tseem ceeb thaum lub sij hawm ua pa ntawm tes: NAD + ( nicotinamide adenine dinucleotide yog tsim los ntawm nicotinamide , qhia hauv qab no) thiab FAD (flavin adenine dinucleotide).
Ntawm no, cov khoom siv hluav taws xob yog dab tsi thiab lawv ua dab tsi tshwj xeeb?
Ib electron cab kuj yog molecule uas thauj electrons thaum ua pa ntawm tes. NAD yog ib electron cab kuj siv los khaws lub zog ib ntus thaum lub sijhawm ua pa ntawm tes. Lub zog no yog khaws cia los ntawm kev txo cov tshuaj tiv thaiv NAD + + 2H NADH + H +.
Lub luag haujlwm ntawm electron carrier molecules hauv lub zog ua haujlwm yog dab tsi?
Electron cab kuj molecules ua raws li lawv lub npe hais. Lawv nqa electrons los ntawm ib feem ntawm ib qho zog ua system rau lwm tus, muab qhov tsim nyog zog thiab txo hwj chim ua kom muaj tshuaj lom neeg tshwm sim.

Vim li cas cov hluav taws xob sab nraud tsuas yog suav nrog hauv daim duab kos duab hluav taws xob?
Atoms nrog 5 los yog ntau tshaj valence electrons tau electrons tsim ib tug tsis zoo ion, los yog anion. Vim li cas thiaj li cov hluav taws xob sab nraud tsuas yog cov uas suav nrog hauv daim duab orbital filling? lawv tsuas yog cov uas koom nrog cov tshuaj tiv thaiv thiab kev sib raug zoo. 2s orbital nyob deb ntawm lub nucleus txhais tau tias nws muaj zog ntau dua
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Vim li cas cov kab hluav taws xob ua hluav taws xob yog perpendicular rau equipotential nto?
Txij li cov kab hluav taws xob hluav taws xob taw qhia radiallyaway ntawm tus nqi, lawv yog perpendicular mus rau cov kab hluav taws xob. Lub peev xwm yog tib yam nyob rau hauv txhua txoj kab uas muaj peev xwm, txhais tau hais tias tsis muaj haujlwm yuav tsum tau txav mus los ntawm ib qho ntawm cov kab no
Lub zog rau kev thauj mus los ntawm qhov twg thiab vim li cas thiaj li xav tau lub zog rau kev thauj mus los?
Kev thauj mus los nquag yog txheej txheem uas yuav tsum tau txav cov molecules tawm tsam qhov concentration gradient. Cov txheej txheem yuav tsum muaj zog. Lub zog rau cov txheej txheem tau txais los ntawm kev rhuav tshem cov piam thaj siv oxygen hauv kev ua pa aerobic. ATP yog tsim thaum ua pa thiab tso tawm lub zog rau kev thauj mus los
