Hauv eukaryotes, ib qho tseem ceeb electron thauj saw muaj nyob rau hauv lub puab mitochondrial membrane qhov twg nws ua hauj lwm raws li qhov chaw ntawm oxidative phosphorylation los ntawm kev ua ntawm ATP synthase. Nws kuj pom muaj nyob rau hauv thylakoid membrane ntawm chloroplast hauv photosynthetic eukaryotes.

Cov neeg kuj nug, dab tsi yog cov cab kuj nyob rau hauv lub electron thauj saw?

Cov Lus Qhia: Cov saw hlau thauj hluav taws xob (ETC) yog cov neeg siv khoom loj ntawm O2 hauv cov tsiaj txhu. Lub ETC kis electrons los ntawm NADH thiab FADH2 rau protein complexes thiab mobile electron cab kuj. Coenzyme Q (CoQ) thiab cytochrome c (Cyt c) yog mobile electron cab kuj nyob rau hauv ETC, thiab O2 yog zaum kawg electron txais.

Ib yam li ntawd, cov saw hlau thauj electron nyob qhov twg hauv daim duab ntawm mitochondrion hauv qab no? Cov electron thauj saw yog nyob nyob rau hauv lub puab membrane ntawm lub mitochondria , raws li qhia hauv qab no . Cov electron thauj saw muaj ib tug xov tooj ntawm hluav taws xob cov cab kuj. Cov cab kuj coj cov electrons los ntawm NADH thiab FADH2, hla lawv mus saw hlau ntawm complexes thiab hluav taws xob cov neeg nqa khoom, thiab thaum kawg tsim ATP.

Tsuas yog li ntawd, qhov twg cov protons tuaj ntawm hauv electron thauj saw?

Cov electron thauj saw yog ib tug series ntawm hluav taws xob transporters embedded nyob rau hauv lub puab mitochondrial membrane uas shuttles electrons los ntawm NADH thiab FADH2 rau molecular oxygen. Hauv cov txheej txheem, protons yog pumped los ntawm mitochondrial matrix mus rau qhov chaw intermembrane, thiab cov pa oxygen raug txo kom tsim dej.

Muaj pes tsawg ATP raug tsim nyob rau hauv cov saw hlau thauj electron?
