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.

Xav txog qhov no, qhov twg electron thauj saw nyob rau hauv cellular respiration?

Electron Transport Chain . Cov kauj ruam kawg ntawm cellular ua pa yog cov electron thauj saw . Cov electron thauj saw xav tau oxygen, uas txhais tau hais tias nws yog cov txheej txheem aerobic. Nws yuav siv qhov chaw nyob rau hauv lub folds ntawm lub puab membrane ntawm lub mitochondria.

Kuj Paub, txhua kauj ruam ntawm kev ua pa ntawm tes tshwm sim nyob qhov twg? Cellular ua pa tshwm sim Nyob rau hauv ob qho tib si eukaryotic thiab prokaryotic hlwb, nrog rau feem ntau tshwm sim nyob rau hauv lub cytoplasm ntawm prokaryotes thiab nyob rau hauv lub mitochondria ntawm eukaryotes. Muaj peb theem tseem ceeb ntawm cellular ua pa : glycolysis, citric acid voj voog, thiab electron thauj / oxidative phosphorylation.

Tsis tas li lo lus nug yog, dab tsi tshwm sim hauv electron thauj saw hauv cellular respiration?

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. Nyob rau hauv tus txheej txheem, protons yog pumped los ntawm lub mitochondrial matrix mus rau lub intertermembrane qhov chaw, thiab oxygen yog txo mus rau hauv dej.

Yuav ua li cas tshwm sim nyob rau hauv ib tug electron thauj saw?

Siab zog electrons yog thauj los ntawm ib tus neeg nqa khoom mus rau lwm tus. Txhua 2 lub zog loj electrons hla dhau Electron Transport Chain , lawv lub zog yog siv los thauj Hydrogen ions hla lub membrane.
