Redox

Isakhono redox i amandla ombane oluhlala electrode ibekwe isisombululo equlathe umthamo othile kweenkqubo redox. iinkqubo ezinjalo, kuba elifutshane, eli nqaku liza kubizwa ngokuba OBC. A ngumqathango lokuqulunqa kunye nokunyuswa yesakhiwo kukuba i electrode apho livela khona, iye metal egalelwe.

Umva SMF, okanye inkqubo redox, - sisisombululo apho into ekhoyo ngandlela oxidized kwaye yehlise ngaxeshanye. Nganye kwezi fom siya kwenziwa kwenye indlela abasabela lohlobo redox. Enye ilizwi, uhlobo izinto ndikho isisombululo enjalo, woba ezinokuba ingathityazwa. Umzekelo elula inkqubo redox sisisombululo apho kukho anions okanye ukuse- metal mnye, kodwa valency yabo yahlukile.

Kwiinkqubo ezinjalo, utshintsho ukusuka kwesinye isimo ukuya kwenye into kwenziwa ngokusebenzisa transfer electron kwi kulwalathiso ifomu lifinyele. Iinkqubo ezinjalo ezinye enzayim zokuphefumla, nto leyo kumafa yayo iqulethe hemin. amakhono abo redox kumiselwa ngokungqinelana nemithetho evulekileyo Claus Peters. Kwihlabathi eziphilayo, kukho imali eyaneleyo kwiinkqubo redox, apho leenguqu ikhutshwa phandle kungekhona ukutshintshwa elektroni, kodwa inani ngokulinganayo protons.

Phantsi kweemeko kwelebhu amandla redox umiselwa ngokusebenzisa indlela potentiometric. technology yayo yile ilandelayo: Zombini i electrode egalelwe kuqala ibekwe yesisombululo enye, yaye ngoko izisombululo ezahlukeneyo, kodwa leyo oqhagamshelwano phakathi bond electrolytic sivumele izisombululo mix. Ukususela imali umahluko umiselwa iziqalelo transfer kunye igugu.

Ukuze umlinganiselo nayo kusetyenziswa indlela Colorimetric apho wemilinganiso wenziwe izikhombisi ezizodwa.

Kungakhathaliseki ukuba uhlobo zomlinganiselo ukuze kuqondwe ukuba ixabiso izinto redox enokuba njenge isibonisi jikelele okungenisa inkqubo iimpawu redox, kwaye umthamo walo igcwala. Indlela yokuphumelela inkqubo redox kulula ngokwaneleyo ukuba baqonde. Ngo-sikhokelo yoMgaqo-SMF kunye enesakhono, oko yiluciferase i SMF, nto leyo iba amandla redox zobukhulu ngaphantsi. Umlinganiselo lungaba imisela umlinganiselo wamandla apho iqulethwe kwiinkqubo redox esivulekayo indalo.

Ezi nkqubo ukulungiselela ubukho eziphilayo nganye kuba intshukumo electron abotshelelweyo, ngoko, kunye kukhululwe umlinganiselo othile wamandla ukugcina homeostasis kunye iseli ngokutsha.

Umzekelo, eqhelekileyo, okanye umgangatho redox enokuba nalo le umzimba womntu kuluhlu - 200 MV - + 100 MV, ebonisa ukuba uhlobo kuncitshiswa yokusingqongileyo lwangaphakathi. Xa sokulinganisa isakhono, kufuneka ukwanelisa imeko: ukuba bafumane iinkcukacha ezithembekileyo zokuthelekisa, imilinganiselo kufuneka lwenziwe phantsi kweemeko ezifanayo physico-chemical. Ukuba ngokufanayo womuntu, iimeko ukuba umlinganiselo redox okunokwenzeka emanzini, kunokwenzeka ukuba bangabhaqa ukuba ixabiso layo phantse lonk eyakhayo kwaye lixabiso ukusuka 200 ukuya 300 MV. Loo ukungangqinelani kwezi amaxabiso umthamo wamanzi kunye umzimba womntu, bathi ukuba electron emzimbeni aziphathe ngendlela kakhulu esebenzayo ngakumbi kunokuba isisombululo zolwelo. Ngokuyenza, oku kuthetha ukuba amanzi izikhombisi ezinjalo, bangene umzimba womntu ongena ngqo kwinkqubo igcwala.

Le propati isetyenziselwa kukulungiswa izikhombisi ezinjalo OBC, nto leyo umzimba wethu. Amanzi, ukuba elibi isalathiso isakhono, isetyenziswa component ezinkulu (kwaye ngokuzimeleyo) nawokulungiselela iziyobisi uzinzise intsalela redox.
