Sab hauv Membrane . Cov sab hauv los yog cytoplasmic daim nyias nyias , impermeable rau polar molecules, tswj kev nkag mus ntawm cov as-ham, metabolites, macromolecules, thiab cov ntaub ntawv nyob rau hauv thiab tawm ntawm lub cytoplasm thiab tswj lub proton motive quab yuam yuav tsum tau rau lub zog cia.
Ib yam li ntawd ib tug yuav nug, dab tsi yog lub ntsiab lus ntawm puab mitochondrial membrane?
Cov sab hauv mitochondrial membrane (IMM) yog mitochondrial membrane uas cais cov mitochondrial matrix los ntawm qhov chaw interemmbrane.
Ib sab saum toj no, qhov chaw nruab nrab ntawm sab hauv thiab sab nrauv hu ua dab tsi? Hauv cell biology, nws yog feem ntau piav raws li cheeb tsam nruab nrab ntawm daim nyias nyias thiab cov sab nrauv membrane ntawm mitochondrion lossis chloroplast. Nws kuj hais txog cov qhov chaw nruab nrab ntawm sab hauv thiab sab nrauv nuclear daim nyias nyias ntawm lub hnab ntawv nuclear, tab sis feem ntau hu ua lub perinuclear qhov chaw.
Ib sab ntawm qhov no, puas yog Cristae zoo ib yam li cov ntaub ntawv sab hauv?
Cov sab nrauv membrane ncig lub mitochondria. Nws yog semi-permeable daim nyias nyias zoo ib yam li lub cell daim nyias nyias . Cov sab hauv daim nyias nyias yog impermeable. Cov folds tsim los ntawm cov sab hauv daim nyias nyias yog lub npe hu ua cristae , uas muaj cov proteins thiab molecules uas koom nrog hauv kev ua pa ntawm tes.
Yuav ua li cas cov txheej txheem tshwm sim nyob rau hauv lub puab mitochondrial membrane?
oxidative phosphorylation
Pom zoo:
Dab tsi yog siv lub puab tsaig sab sauv hauv vernier caliper?
Lub puab tsaig sab saud yog qhov me me, nkhaus sab hauv, thiab yog siv los ntsuas qhov ntev ntawm cov khoom hollow xws li lub tog raj kheej thiab lwm yam. Ib qho vernier calipers uas tseem hu ua Slide Calipers
Yog vim li cas yog lub puab membrane ntawm mitochondria?
Lub mitochondrial sab hauv daim nyias nyias yog qhov chaw ntawm electron thauj saw, ib kauj ruam tseem ceeb hauv kev ua pa aerobic. Nyob nruab nrab ntawm lub puab membrane thiab txheej membrane yog inter-membrane chaw. Nyob ntawd, H + ions tsim los tsim lub peev xwm proton uas pab txhawb lub zog ATP lub zog tsim
Lub luag haujlwm ntawm lub cell membrane yog dab tsi thaum lub sijhawm thauj mus los?
Lub cell membrane yog xaiv permeable rau ions thiab organic molecules thiab tswj kev txav ntawm cov khoom hauv thiab tawm ntawm lub hlwb. Lub luag haujlwm tseem ceeb ntawm cov cell membrane yog los tiv thaiv lub cell ntawm nws ib puag ncig. Nws muaj phospholipid bilayer nrog embedded proteins
Dab tsi yog qhov zoo ntawm folded puab membrane hauv mitochondria?
Kev ua haujlwm ntawm folds hauv mitochondria yog ua kom thaj chaw saum npoo. Qhov no sab hauv folded ib feem ntawm mitochondria (lub puab daim nyias nyias) yog lub luag hauj lwm rau cell respiration (tus txheej txheem ntawm zom cov carbohydrates (qab zib) kom lub zog)
Lub puab tsaig ntawm lub puab tsaig yog dab tsi?
Lub puab tsaig ntawm lub puab tsaig yog dab tsi thiab koj tuaj yeem pom cov duab ntawm lub puab tsaig ntawm lub puab tsaig? Cov no feem ntau tsis sib xws thiab yog ib txwm tiaj tus. Cov cell yog tsim los ntawm ntau qhov chaw nrog rau ib daim nyias nyias nyias nyob rau sab nraud ntawm tes. Cov no tuaj yeem pom tau yooj yim nyob rau hauv microscope
