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.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Puas yog mitochondrial DNA tib yam li nuclear DNA?
Nuclear DNA thiab mitochondrial DNA txawv ntawm ntau txoj hauv kev, pib nrog qhov chaw thiab cov qauv. Nuclear DNA nyob rau hauv lub nucleus ntawm eukaryote hlwb thiab feem ntau muaj ob daim ntawv theej rau ib lub xovtooj ntawm tes thaum mitochondrial DNA nyob rau hauv mitochondria thiab muaj 100-1,000 daim ntawv rau ib lub cell
Dab tsi yog qhov txawv ntawm mitochondrial thiab nuclear DNA?
Txhawm rau suav nws, qhov sib txawv ntawm lawv yog: Nuclear DNA pom nyob rau hauv lub nucleus ntawm lub cell thaum mitochondrial DNA pom tsuas yog hauv mitochondria ntawm lub cell. Nuclear DNA tau txais los ntawm leej niam thiab leej txiv ob qho tib si ntawm qhov tod tes, mitochondrial DNA tau txais los ntawm leej niam nkaus xwb
Mitochondrial oxidative phosphorylation yog dab tsi?
Oxidative phosphorylation (UK /?kˈs?d. ?. s?ˌde?. t?v/ lossis electron transport-linked phosphorylation) yog txoj hauv kev uas cov hlwb siv cov enzymes los oxidize cov as-ham, yog li tso tawm lub zog uas siv los tsim adenosine. triphosphate (ATP). Hauv feem ntau eukaryotes, qhov no tshwm sim hauv mitochondria
