Cov mitochondrial respiratory chain yog muaj tsib lub enzyme complexes uas ua ke tsav cov txheej txheem ntawm oxidative phosphorylation thiab tswj cov proton gradient los ntawm uas adenosine triphosphate (ATP) ntau lawm yog khaws cia.

Kuj tseem paub yog, dab tsi yog cov enzymes uas pleev complexes I IV nyob rau hauv mitochondrial respiratory saw?

Cov txoj hlab pa suav nrog plaub cov protein ntau complexes (I- IV ) as well as ATP synthase (AS). Tag nrho cov no yog embedded nyob rau hauv lub puab mitochondrial daim nyias nyias. Coenzyme Q (Q) thiab cytochrome C (C) yog diffusible electron cab kuj.

Tsis tas li ntawd, kab mob ua pa hauv biochemistry yog dab tsi? … ntu ntawm cov tshuaj tiv thaiv hu ua txoj hlab pa nyob rau hauv daim nyias nyias ntawm mitochondrion. Qhov no saw hlau yog ib tug series ntawm cov cab kuj (ubiquinone thiab ntau yam hlau-muaj tshuaj hu ua cytochromes) uas thaum kawg hloov cov hydrogen thiab electrons ntawm cov coenzymes rau molecular oxygen, tsim dej.

Ib yam li ntawd, nws raug nug, mitochondrial ua pa yog dab tsi?

Mitochondrial ua pa yog cov txheej txheem metabolic thiab cov txheej txheem xav tau cov pa oxygen uas tshwm sim hauv mitochondria los hloov lub zog khaws cia hauv macronutrients mus rau adenosine triphosphate (ATP), universal zog pub rau hauv lub cell.

Yog vim li cas electron thauj saw hu ua pa saw?

Cov electron thauj saw (Daim duab 1) yog qhov kawg ntawm aerobic ua pa thiab tsuas yog ib feem ntawm cov piam thaj metabolism uas siv oxygen atmospheric. Oxygen txuas ntxiv mus rau hauv cov nroj tsuag; nyob rau hauv cov tsiaj, nws nkag mus rau hauv lub cev los ntawm lub ua pa qhov system.
