Vim li cas NADH thiab FADH2 tsim 3 ATPs thiab 2 ATPs raws? 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.
Hais txog qhov no, pes tsawg ATP molecules feem ntau yog tsim los ntawm 4 NADH?
Muaj qhov theoretical siab tshaj plaws ntawm 38 ATP ua los ntawm ib qho kua nplaum molecule: 2 NADH ua rau glycolysis ( 3 ATP txhua) + 8 NADH tsim tawm hauv Krebs cycle ( 3 ATP txhua) + 2 FADH2 tsim Kuv tsis paub qhov twg ( 2 ATP ib) + 2 ATP tsim tawm hauv Krebs cycle + 2 ATP ua hauv glycolysis = 6 + 24 + 4 + 2 + 2 = 38 PAB, Ib tug kuj nug, 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.
Dhau li ntawm no, pes tsawg molecules ntawm ATP raug tsim?
Qhov peev xwm no yog siv los tsav ATP synthase thiab tsim ATP los ntawm ADP thiab ib pab pawg phosphate. Phau ntawv Biology feem ntau hais tias 38 ATP molecules tuaj yeem yog ua rau oxidized qabzib molecule Thaum lub sij hawm ua pa ntawm tes (2 los ntawm glycolysis, 2 los ntawm Krebs lub voj voog, thiab txog 34 los ntawm electron thauj system).
Muaj pes tsawg ATP raug tsim los ntawm 10 NADH uas tau tsim thaum lub sij hawm citric acid?

Pom zoo:
Muaj pes tsawg daim ntawv cog lus feem ntau tsim los ntawm nitrogen?
Nitrogen (5 valence electrons) feem ntau tsim peb daim ntawv cog lus thiab khaws cia ib leeg ib leeg los sau nws cov octet
Muaj pes tsawg ATP yog tsim los ntawm ib tug pyruvate?
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 .
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
Yuav ua li cas muaj pes tsawg tus noob sib xyaw ua tau hauv gamete ntau lawm rau Dihybrid cross Vim li cas thiaj muaj ntau?
Muaj peev xwm gametes rau txhua tus niam txiv AaBb Txij li thaum txhua tus niam txiv muaj plaub qhov sib txawv ntawm cov alleles hauv gametes, muaj kaum rau kev sib txuas ua ke rau tus ntoo khaub lig no
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)
