Raws li cov electrons raug pauv los ntawm ib qho electron cab kuj rau lwm tus, lawv lub zog theem qis, thiab lub zog raug tso tawm. Cytochromes thiab quinones (xws li coenzyme Q) yog qee yam piv txwv ntawm cov khoom siv hluav taws xob.
Ib sab ntawm no, dab tsi yog 3 electron cab kuj?
Oxidation-txo cov tshuaj tiv thaiv ib txwm tshwm sim hauv cov khub sib tw; tsis muaj molecule tuaj yeem oxidized tshwj tsis yog lwm qhov txo qis
- Flavin Adenine Dinucleotide. Flavin adenine dinucleotide, los yog FAD, muaj riboflavin txuas rau adenosine diphosphate molecule.
- Nicotinamide Adenine Dinucleotide.
- Coenzyme Q.
- Cytochrome C.
Qhov thib ob, cov khoom siv hluav taws xob feem ntau yog dab tsi? Hauv kev ua pa ntawm tes, muaj ob qho tseem ceeb cov khoom siv hluav taws xob , nicotinamide adenine dinucleotide (abbreviated li NAD+ nyob rau hauv nws daim ntawv oxidized) thiab flavin adenine dinucleotide (abbreviated li FAD hauv nws daim ntawv oxidized).
Yog li ntawd, cov khoom siv hluav taws xob yog dab tsi thiab lawv ua dab tsi?
Ib electron cab kuj yog molecule uas thauj electrons thaum ua pa ntawm tes. NAD yog ib electron cab kuj siv los khaws lub zog ib ntus thaum lub sijhawm ua pa ntawm tes. Lub zog no yog khaws cia los ntawm kev txo cov tshuaj tiv thaiv NAD + + 2H NADH + H +.
Puas yog NADH yog cov khoom siv hluav taws xob?
Cov Electron Carriers NADH thiab NADPH. NAD+/ NADH thiab NADP + / NADPH yog cov khoom siv hluav taws xob . Thiab lawv muaj nuj nqis vim electrons ua lub luag haujlwm tseem ceeb hauv kev ua ntau yam kev cuam tshuam hauv lub cev. NADH Nws yog ib qho tseem ceeb uas paub txog nws lub luag haujlwm hauv kev tsim ATP, uas ua haujlwm ua roj rau lub cev.

Yuav ua li cas yog ib tug piv txwv ntawm cov pejxeem nyob rau hauv ib tug ecosystem?
Cov pejxeem yog ib pawg ntawm tib cov kab mob uas nyob hauv ib cheeb tsam. Qee zaum cov neeg sib txawv nyob hauv tib cheeb tsam. Piv txwv li, nyob rau hauv ib lub hav zoov yuav muaj cov pej xeem ntawm owls, nas thiab ntoo thuv. Ntau haiv neeg nyob hauv tib cheeb tsam hu ua ib lub zej zog
Yuav ua li cas yog ib tug piv txwv ntawm ib tug caldera volcano?
Lub roob hluav taws kub caldera yog ib qho kev nyuaj siab nyob rau hauv av tsim los ntawm lub cev qhuav dej tom qab ib tug volcanic eruption. Qee zaum, lub caldera yog tsim maj mam, thaum av los tom qab lub magma chamber yog khoob. Lwm qhov piv txwv ntawm volcanic caldera yog Yellowstone Caldera, uas tau tawg 640,000 xyoo dhau los
Yuav ua li cas yog ib tug piv txwv ntawm ib tug multifactorial congenital teeb meem?
Feem ntau cov kab mob congenital congenital muaj xws li: Neural tube defects. Isolated hydrocephalus. Clubfoot. Cleft di ncauj thiab/los yog palate
Yuav ua li cas yog ib tug piv txwv ntawm ib tug rational naj npawb uas tsis yog ib tug tag nrho?
Tus lej "rational" yog qhov piv ntawm ob tus lej. Piv txwv li, cov hauv qab no yog cov lej rational, thiab tsis muaj leej twg yog tus lej: 1 / 2. 2 / 3
Vim li cas cov neeg caij tsheb yuav tsum tau pab los ntawm cov cab kuj molecule?
Vim li cas cov neeg caij tsheb yuav tsum tau pab los ntawm cov cab kuj molecule? Cov neeg caij tsheb molecules xav tau kev pab vim lawv tsis tuaj yeem haum los ntawm cov cell membrane. Yooj yim diffusion nrog kev pab los ntawm cov cab kuj molecule tsis xav tau lub zog, nws mus los ntawm ntau dua concentration mus rau qis concentration
