Kev ua haujlwm ntawm ATP ntau lawm
| Kauj ruam | coenzyme tawm los | ATP yield |
|---|---|---|
| Glycolysis them nyiaj theem | 2 NADH | 3o5 ib |
| Oxidative decarboxylation ntawm pyruvate ua | 2 NADH | 5 |
| Krebs lub voj voog | 2 | |
| 6 NADH | 15 |
Tsis tas li ntawd, cov khoom ntawm pyruvate oxidation yog dab tsi?
Zuag qhia tag nrho, pyruvate oxidation converts pyruvate-ib peb-carbon molecule-rau hauv acetyl CoA pib ntawv, C, o, A, kawg ntawv-ib ob-carbon molecule txuas rau Coenzyme A - tsim cov ntawv NADHstart, N, A, D, H, cov ntawv kawg thiab tso tawm ib qho carbon dioxide molecule hauv cov txheej txheem.
Muaj pes tsawg NADH raug tsim hauv glycolysis? ob NAD
Ib yam li ntawd, pes tsawg fadh2 raug tsim nyob rau hauv pyruvate oxidation?
Ob lub acetyl carbon atoms thaum kawg yuav raug tso tawm tom qab lem ntawm lub voj voog; Yog li, tag nrho rau cov pa roj carbon atom los ntawm thawj cov piam thaj molecule tau muab tso rau hauv carbon dioxide. Txhua qhov tig ntawm lub voj voog ua peb NADH molecules thiab ib qho FADH 2 molecule.
Muaj pes tsawg NADH thiab fadh2 raug tsim hauv glycolysis?
Txij li thaum glycolysis ntawm ib qho qabzib molecule tsim ob acetyl CoA molecules, cov tshuaj tiv thaiv nyob rau hauv glycolytic txoj kev thiab citric acid voj voog tsim tawm six CO2 molecules, 10 NADH molecules, thiab ob FADH 2 molecules rau cov piam thaj molecule (Table 16-1).

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 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 nyob rau hauv pyruvate oxidation?
Thaum lub sij hawm them nyiaj ntawm glycolysis, plaub pawg phosphate raug xa mus rau ADP los ntawm substrate-theem phosphorylation los ua plaub ATP, thiab ob NADH yog tsim thaum cov pyruvate oxidized
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)
