ob ATP

Hais txog qhov no, puas yog ib qho ATP siv hauv cov saw hlau thauj hluav taws xob?

Tsis muaj ATP yog tsim nyob rau hauv lub electron thauj saw . Lub npe ntawm cov protein embedded uas muab cov channel rau hydrogen ions kom dhau los ntawm daim nyias nyias yog ATP synthase. Kev khiav ntawm hydrogen ions los ntawm cov protein channel muab lub zog pub dawb los ua haujlwm.

Ib yam li ntawd, 36 ATP ua li cas? Cellular ua pa ua 36 tag nrho ATP ib molecule ntawm qabzib hla peb theem. Kev rhuav tshem cov kev sib txuas ntawm carbons hauv cov piam thaj molecule tso tawm lub zog. Kuj tseem muaj cov hluav taws xob hluav taws xob siab uas raug ntes nyob rau hauv daim ntawv ntawm 2 NADH (electron carriers) uas yuav siv tau tom qab hauv cov saw hlau thauj electron.

Tsis tas li ntawd, yuav ua li cas ATP yog tsim nyob rau hauv lub electron thauj saw?

Cov txheej txheem ntawm kev tsim ATP los ntawm electron thauj saw yog hu ua oxidative phosphorylation. Hluav taws xob nqa los ntawm NADH + H+ thiab FADH2 yog pauv mus rau oxygen ntawm ib tug series ntawm hluav taws xob cov cab kuj, thiab ATPs yog tsim . Peb ATPs yog tsim los ntawm txhua NADH + H+, thiab ob ATPs yog tsim rau txhua FADH2 hauv eukaryotes.

Puas yog NADH 2.5 lossis 3 ATP?

Yuav kom dhau cov electrons los ntawm NADH mus kawg Oxygen txais, tag nrho ntawm 10 protons raug thauj los ntawm matrix mus rau inter mitochondrial membrane. 4 protons ntawm complex 1, 4 ntawm complex 3 thiab 2 ntawm complex 4. Yog li rau NADH - 10/4= 2.5 TSI yog ua ua tau. Ib yam li ntawd rau 1 FADH2, 6 protons raug txav mus li 6/4 = 1.5 ATP yog ua.
