2 ATP
Ib yam li ntawd, nws tau nug, pes tsawg ATP raug tsim los ntawm txhua pyruvate?
Rau aerobic ua pa, nws yog hais txog 30 ATP rau 2 pyruv. Tag nrho txog 32 tag nrho net ATP yog tsim rau ib qabzib, tab sis 2 ntawm cov no yog los ntawm glycolysis, yog li tsis suav rau pyruvate ua . Glycolysis tsim tawm 2 pyruvate ib qabzib thiab lawv mus ua lwm yam 30 ATP.
Kuj Paub, muaj pes tsawg ATP raug tsim nyob rau hauv glycolysis? Cov txiaj ntsig ntawm Glycolysis . Glycolysis pib nrog ib molecule ntawm qabzib thiab xaus nrog ob pyruvate (pyruvic acid) molecules, tag nrho ntawm plaub ATP molecules, thiab ob molecules ntawm NADH.
Ua raws li qhov xav tau, 36 ATP tsim tau 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.
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.

Muaj pes tsawg ATP molecules feem ntau yog tsim los ntawm NADH?
Vim li cas NADH thiab FADH2 tsim 3 ATPs thiab 2 ATPs feem? NADH tsim 3 ATP thaum lub sij hawm ETC (Electron Transport Chain) nrog oxidative phosphorylation vim NADH muab nws cov hluav taws xob rau Complex I, uas yog nyob rau theem siab dua li lwm cov Complexes
Muaj pes tsawg ATP raug tsim nyob rau hauv acetyl CoA tsim?
Txhua acetyl-CoA yields 3 NADH + 1 FADH2 + 1 GTP (= ATP) thaum lub sij hawm Krebs. Xav txog qhov nruab nrab ntawm 3 ATP / NADH thiab 2 ATP / FADH2 siv cov saw ua pa, koj muaj 131 ATP molecules
Muaj pes tsawg NADH tsim los ntawm pyruvate oxidation?
Kev ua tau zoo ntawm ATP ntau lawm Kauj Ruam coenzyme yield ATP tawm los Glycolysis them nyiaj theem 2 NADH 3 lossis 5 Oxidative decarboxylation ntawm pyruvate 2 NADH 5 Krebs cycle 2 6 NADH 15
Muaj pes tsawg hom tshuaj lom neeg muaj pes tsawg leeg?
Hauv chaw ua haujlwm muaj ob hom kev phom sij: kev noj qab haus huv thiab kev phom sij ntawm lub cev
Yuav ua li cas muaj pes tsawg molecules ntawm carbon dioxide yog tsim thaum ib tug pyruvate molecule ua tiav los ntawm aerobic ua pa?
Lub yim kauj ruam ntawm lub voj voog yog cov tshuaj lom neeg cov tshuaj tiv thaiv uas ua rau cov hauv qab no los ntawm txhua qhov ntawm ob lub molecules ntawm pyruvate uas ua rau ib molecule ntawm qabzib uas tau pib mus rau hauv glycolysis (Daim duab 3): 2 carbon dioxide molecules. 1 ATP molecule (los yog sib npaug)
