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.

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
Vim li cas 9 Fluorenone ntau dua polar dua fluorene?
Cov tshuab hnyav tau cais cov fluorene thiab 9-fluorenone raws li lawv qhov sib txawv ntawm cov qauv thiab polarity. Nyob rau hauv txoj cai, cov tshuaj compound uas ntws los ntawm kem ntawm ib tug ceev ceev yog ntau tsis-polar; Yog li ntawd, nyob rau hauv cov ntaub ntawv no fluorene yog ntau tsis-polar tshaj 9-fluorenone
Yog vim li cas thermal khiav ntawm atmospheric gas ntau yooj yim dua los ntawm lub hli dua los ntawm lub ntiaj teb?
Yog vim li cas thermal khiav ntawm atmospheric gas ntau yooj yim dua los ntawm lub hli dua los ntawm lub ntiaj teb? Vim lub hli lub ntiajteb txawj nqus muaj zog npaum li lub ntiaj teb. Cov pa oxygen tso tawm los ntawm lub neej raug tshem tawm ntawm qhov chaw los ntawm cov tshuaj lom neeg nrog cov pob zeb nto kom txog thaum lub pob zeb nto tuaj yeem nqus tsis tau ntxiv
Vim li cas cov kab mob feem ntau tsim cov xeeb ntxwv ntau dua li muaj sia nyob?
Cov kab mob tsim cov xeeb ntxwv ntau dua li qhov muaj sia nyob. Cov kab mob tuaj yeem tuag los ntawm ntau yam ua rau: kab mob, kev tshaib plab, thiab noj, thiab lwm yam. Ib puag ncig tsis tuaj yeem txhawb nqa txhua yam kabmob uas yug los. Ntau tus tuag ua ntej lawv muaj peev xwm rov tsim dua
Vim li cas cov khoom hnyav dua muaj inertia ntau dua?
Newton thawj txoj cai piav qhia tias cov khoom tseem nyob qhov twg los yog txav mus rau ntawm qhov nrawm nrawm tshwj tsis yog lub zog ua rau lawv. Qhov hnyav (los yog loj) ntawm ib yam khoom, qhov ntau inertia nws muaj. Cov khoom hnyav yog qhov nyuaj txav dua li lub teeb vim tias lawv muaj inertia ntau dua
