Cov khoom siv hluav taws xob muaj cov molecules tseem ceeb hauv cov kab mob lom. Lawv txais electrons thiab txav lawv los ua ib feem ntawm cov hluav taws xob thauj saw, hloov lub hluav taws xob , thiab lub zog nws sawv cev, kom lub zog ntawm tes. Cov khoom siv hluav taws xob muaj Qhov tseem ceeb ntawm kev ua pa ntawm tes thiab photosynthesis.
Hauv qhov no, cov khoom siv hluav taws xob yog dab tsi thiab lawv lub hom phiaj yog dab tsi?
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 ntawm tus txo cov tshuaj tiv thaiv NAD + + 2H NADH + H +.
Tsis tas li ntawd, dab tsi yog txo cov neeg nqa hluav taws xob? Ib tug xov tooj ntawm molecules yuav ua raws li cov khoom siv hluav taws xob nyob rau hauv biological systems. NAD+ txais ib hydrogen ion (H+) thiab ob electrons (2 e−), raws li nws ua txo rau NADH + H+. NADH tsiv mus rau lub hluav taws xob thauj saw thiab pub ib khub ntawm electrons (ua oxidized) rau thawj qhov sib xyaw hauv cov saw hlau.
Ua raws li qhov kev pom no, dab tsi yog lub tshuab nqa hluav taws xob?
electron cab kuj . Ib qho ntawm ntau yam molecules uas muaj peev xwm lees txais ib lossis ob electrons los ntawm ib tug molecule thiab pub lawv mus rau lwm tus nyob rau hauv tus txheej txheem ntawm hluav taws xob thauj. Raws li cov electrons raug pauv los ntawm ib qho electron cab kuj rau lwm tus, lawv lub zog theem qis, thiab lub zog raug tso tawm.
Cov neeg nqa hluav taws xob mus qhov twg?
Cov cov khoom siv hluav taws xob coj cov electrons mus rau ib pab pawg neeg ntawm cov protein nyob rau hauv lub puab membrane ntawm lub mitochondrion, hu ua lub hluav taws xob thauj saw. Raws li electrons txav mus los ntawm hluav taws xob thauj saw, lawv mus los ntawm qhov siab dua mus rau qib qis zog thiab yog Thaum kawg kis mus rau oxygen (ua dej).

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
Cov cuab yeej hluav taws xob siv hluav taws xob ntau npaum li cas?
Tsis tas li ntawd, nco ntsoov txhua yam cuab yeej uas tuaj yeem xaim los khiav ntawm 240 volts es tsis yog tus qauv 120. Tus qauv amperage rau cov cuab yeej hluav taws xob me (sander, jigsaw, thiab lwm yam) yog 2 txog 8 amps. Rau cov cuab yeej hluav taws xob loj (router, ncig pom, tablesaw, tshuab dhos thiab lwm yam), 6 txog 16 amps yog qhov raug
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
