Homogenization : Qhov raug tshem tawm hlwb yog ces cuam tshuam los ntawm cov txheej txheem ntawm homogenization . (ii) Siab Siab (Fabkis Xovxwm lossis Nitrogen Bomb), Cov kua uas muaj kev ncua ntawm cell organelles thiab ether constituents yog hu ua homogenate.
Tsuas yog li ntawd, Cell homogenization yog dab tsi?
Cell homogenization , kuj hu ua cell micronization los yog cell fractionation, yog qhov kev txiav txim ntawm kev txo qhov me me ntawm cov molecules kom yooj yim txawm tias faib thiab emulsification ntawm cov kua, cream, los yog lwm yam nruab nrab. Txhua txoj hauv kev suav nrog kev txhawb nqa hlwb mus lyse, los sis tawg.
Ib tug kuj yuav nug, dab tsi yog txheej txheem ntawm cell fractionation? Cov kws tshawb fawb tuaj yeem pom cov haujlwm ntawm cov organelles los ntawm kev cais lawv hauv ib qho txheej txheem hu ua cell fractionation . Cov txheej txheem yooj yim zoo nkauj; koj coj ib co hlwb , muab pov rau hauv ib rab, thiab ces centrifuge lawv cais cov organelles, raws li qhia nyob rau hauv daim duab no.
Ntxiv mus, cell fractionation txhais li cas?
Cell fractionation yog txheej txheem siv los cais cellular Cheebtsam thaum khaws cia ib tus neeg ua haujlwm ntawm txhua yam. Lwm yam kev siv ntawm subcellular fractionation yog los muab cov khoom muaj protein ntau ntxiv rau kev ua kom huv ntxiv, thiab pab txhawb kev kuaj mob ntawm ntau lub xeev.
Homogenization hauv biochemistry yog dab tsi?
Homogenization , nyob rau hauv cell biology los yog molecular biology, yog ib tug txheej txheem uas sib txawv feem ntawm ib tug biological qauv ua sib npaug zos nyob rau hauv muaj pes tsawg leeg.
Pom zoo:
Cell fractionation ua haujlwm li cas?
Cell fractionation yog txheej txheem uas tso cai rau ntau qhov chaw ntawm lub xov tooj sib cais los ntawm ib leeg siv centrifugation. Thaum cov hlwb tau muab faib ua feem, cov organelles xws li plasma membrane, nucleus, thiab mitochondria tuaj yeem kawm cais
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
Lub hom phiaj ntawm cell fractionation yog dab tsi?
Piav cov txheej txheem thiab lub hom phiaj ntawm cell fractionation. Self fractionation yog ib qho txheej txheem uas coj cov hlwb sib nrug thiab cais cov organelles loj thiab lwm cov qauv ntawm cov cellular los ntawm ib leeg. Lub hom phiaj yog cais / faib cov khoom ntawm tes raws li qhov loj thiab qhov ntom
Dab tsi yog cell membrane hauv prokaryotic cell?
Prokaryotes thiab eukaryotes yog ob hom cell uas muaj nyob. Tab sis, prokaryotes muaj qee cov organelles nrog rau cov cell membrane, kuj hu ua phospholipid bilayer. Cov cell membrane no kaw lub cell thiab tiv thaiv nws, tso cai rau hauv qee cov molecules raws li qhov xav tau ntawm tes
