NADH thiab FADH2 nqa cov hluav taws xob muaj peev xwm muaj zog. Cov electron acceptor molecules tuaj qhov twg los? Cov no molecules tau tsim thaum lub sijhawm glycolysis, cov tshuaj tiv thaiv txuas, thiab Kreb lub voj voog.
Yuav ua li cas molecule ua raws li ib tug txais electron?
Oxygen ua haujlwm raws li lub davhlau ya nyob twg electron txais rau cov saw hlau thauj khoom. Cov hluav taws xob tau pub dawb los ntawm NADH cov molecules thiab dhau los ntawm ntau cov proteins sib txawv los tsim cov proton gradient nyob rau hauv qhov chaw interemmbrane.
Yuav ua li cas ua cov saw hluav taws xob thauj khoom?
Cov saw hlau thauj hluav taws xob yog ib qho ntawm plaub qhov kev sib xyaw ua ke uas ob peb qhov kev cuam tshuam redox, tsim cov tshuaj electrochemical gradient uas ua rau kev tsim ntawm ATP nyob rau hauv ib qho kev ua tiav lub npe hu ua oxidative phosphorylation. Nws tshwm sim hauv mitochondria hauv ob lub cellular respiration thiab photosynthesis.
Dab tsi mus rau hauv cov saw hlau thauj electron thiab nws tuaj qhov twg?
Cov saw hlau thauj hluav taws xob (ETC) yog cov kauj ruam kawg ntawm kev ua pa ntawm tes thiab siv qhov chaw hauv mitochondrion. … Cov txheej txheem yuav siv sij hawm qhov chaw nyob rau hauv lub puab mitochondrial membrane. NADH thiab FADH2, tsim los ntawm glycolysis thiab Kreb lub voj voog, tso lawv cov electrons rau hauv cov saw hlau thauj.
ETC tshwm sim nyob qhov twg?
Kev thauj cov saw hluav taws xob ua haujlwm tshwm sim nyob rau hauv lub puab membrane thiab qhov chaw nruab nrab ntawmsab hauv thiab sab nrauv, hu ua qhov chaw nruab nrab.
