FMN tau txais cov hydrogen los ntawm NADH thiab ob lub electrons. Nws tseem khaws cov proton ntawm lub matrix. Nyob rau hauv daim ntawv no txo, nws kis tau cov electrons rau hlau-sulfur pawg uas yog ib feem ntawm txoj complex, thiab yuam ob protons mus rau hauv lub interemmbrane qhov chaw.

Vim li cas FMN thiaj tsim nyog nyob rau hauv txoj kev I ntawm txoj hlua thauj electron?

Tshwj xeeb, FAD thiab FMN tau koom nrog hauv kev ua haujlwm ntawm cov saw hlau thauj hluav taws xob, ib qhoqhov tseem ceeb ntawm cov metabolism hauv lub zog uas paub tias muaj kev cuam tshuam rau cov neeg muaj HD. … Nws txais cov electrons thiab hloov mus rau FADH2. FADH2 ces hloov nws cov electrons mus rau complex II ntawm lub electron thauj saw.

Lub luag haujlwm ntawm txoj haujlwm 1 hauv cov saw hlau xa hluav taws xob yog dab tsi?

Complex kuv yog thawj enzyme ntawm txoj hlab pa. Nws oxidizes NADH, uas yog tsim los ntawm Krebs lub voj voog hauv mitochondrial matrix, thiab siv ob lub electrons los txo ubiquinone rau ubiquinol.

Puas FMN oxidize NADH?

NADH yog oxidized los ntawm noncovalently khi flavin mononucleotide (FMN), ces xya hlau-sulfur pawg hloov ob electrons rau quinone, thiab plaub protons yog pumped hla lub puab mitochondrial. membrane.

FMN yog dab tsi hauv lwm yam?

Cov saw hlau thauj hluav taws xob muaj plaub hom kev ua haujlwm loj. … Tus txais hluav taws xob hu ua flavin mononucleotide (FMN) rho tawm cov hluav taws xob no ua NADH thiab tom qab ntawd hla lawv mus.mus rau ib pawg ntawm cov hlau-sulfur.
