NADH tsim 3 ATP Thaum lub sij hawm ETC (Electron Transport Chain) nrog oxidative phosphorylation vim NADH muab nws cov electron rau Complex I, uas yog nyob rau theem siab zog tshaj lwm cov Complexes. FADH2 tsim 2 ATP Thaum lub sij hawm ETC vim nws muab nws cov electron rau Complex II, bypassing Complex I.

Ntawm no, NADH thiab fadh2 hloov mus rau ATP li cas?

Nyob rau hauv kev txiav txim rau tau txais tag nrho cov nyiaj ntawm lub zog tso tawm los ntawm kev tawg ntawm qab zib, koj yuav tsum hloov lub siab zog molecules NADH thiab FADH2 rau ATP . Qhov no tshwm sim hauv sab hauv daim nyias nyias ntawm mitochondria. Qhov no frees li electron thauj saw rau coj lwm khub ntawm electrons los ntawm ib tug FADH 2 los yog a NADH.

Qhov thib ob, pes tsawg ATP NADH thiab fadh2 raug tsim nyob rau hauv cellular respiration? Lub zog nce ntawm ib lub voj voog yog 3 NADH, 1 FADH2, Nplooj 4 Cellular respiration 4 thiab 1 GTP; GTP tej zaum yuav raug siv los tsim ATP. Yog li, tag nrho lub zog tawm los ntawm ib qho tag nrho cov piam thaj molecule (2 pyruvate molecules) yog 6 NUG , 2 FADH2, thiab 2 ATP.

Tsis tas li ntawd, vim li cas fadh2 muab 1.5 ATP thiab NADH 2.5 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. Yog li ntawd rau NADH - 10/4= 2.5 TSI yog tsim los tiag. Ib yam li ntawd rau 1 FADH 2 , 6 protons yog tsiv li 6/4 = 1.5 TSI yog tsim.

Puas yog NADH lossis fadh2 ntau electronegative?

NADH thiab FADH 2 xa lawv cov electrons mus rau electron thauj saw. Cov ntau electronegative cov molecule, ntau lub zog yuav tsum tau ua kom lub electron deb ntawm nws. Ua li no, me ntsis electronegative membrane protein yuav rub electrons tawm ntawm cov khoom siv hluav taws xob tsawg.
