Qhov sib txawv tseem ceeb ntawm ribosome thiab centrosome yog ribosome yog ib qho tseem ceeb ntawm cov cell organelle koom nrog cov protein synthesis thaum centrosome yog cell organelle koom nrog hauv cell division.
Lub xovtooj ntawm tes yog cov qauv tsim thiab kev ua haujlwm ntawm cov kabmob muaj sia. Nws muaj cov khoom sib txawv. Cell organelles ua lub luag haujlwm tseem ceeb hauv cov hlwb eukaryotic. Txawm li cas los xij, cov cell prokaryotic tsis muaj cov organelles membrane. Tab sis, cov hlwb no muaj ribosomes. Ribosomes yog qhov tseem ceeb rau kev tsim cov protein ntau hauv cov hlwb. Lub centrosome yog lwm eukaryotic cell organelle uas yog ib qho tseem ceeb hauv kev faib cell. Yog li, tsab xov xwm no tsom mus rau qhov tseem ceeb ntawm qhov sib txawv ntawm ribosome thiab centrosome.
Ribosome yog dab tsi?
Ib ribosome yog ib qho tseem ceeb ntawm cov cell organelle muaj nyob rau hauv ob lub prokaryotic thiab eukaryotic hlwb. Nws yog tus saib xyuas ntawm cov protein synthesis hauv cov kab mob muaj sia. Kev txhais ntawm mRNA tshwm sim hauv ribosomes. Raws li txoj cai, ribosome yog ib qho nyuaj ntawm RNA thiab cov proteins.
Feem ntau, ribosome muaj ob lub RNA-protein complexes hu ua subunit me me thiab loj subunit. Prokaryotic ribosomes muaj 70S nrog 30S me subunits thiab 50S loj subunits. Ntawm qhov tod tes, eukaryotic ribosomes muaj 80S nrog 40S me subunits thiab 60S loj subunits.
Daim duab 01: Ribosome
Ib lub cell muaj ntau ribosomes. Feem ntau, ribosomes ntab ntab hauv cytoplasm ntawm prokaryotic thiab eukaryotic hlwb. Qee qhov eukaryotic ribosomes tshwm sim txuas nrog endoplasmic reticulum.
Centrosome yog dab tsi?
Lub centrosome yog lub cell organelle tseem ceeb rau kev faib cell. Nws yog qhov tseem ceeb ntawm microtubule qhov chaw ntawm lub cell. Raws li txoj cai, lub centrosome yog 1 µm nyob rau hauv loj, thiab nws tsis yog ib tug membrane-bound cell organelle. Tsis tas li ntawd, lub cell faib muaj ob lub centrosomes ntawm ob tug ncej. Ntxiv mus, ib qho centrosome muaj ib lossis ob lub centrioles. Yog li ntawd, txhua mitotic cell feem ntau muaj ob lub centrosomes uas muaj plaub centrioles. Ntawm no, lub centriole yog ib tug me me cylindrical organelle tam sim no nyob rau hauv feem ntau eukaryotic hlwb. Lawv muaj tubulin protein ua lawv cov protein tseem ceeb. Tsis tas li ntawd, cov qauv cylindrical ntawm lub centriole muaj ntau pawg ntawm microtubules uas nyob hauv 9 + 3 qauv. Thaum ob lub centrioles tau teem rau ib leeg, nws tsim ib lub centrosome. Lub centrosome ua haujlwm raws li lub hauv paus tseem ceeb ntawm microtubule kev npaj, thiab nws tswj kev loj hlob ntawm lub voj voog ntawm tes.
Daim duab 02: Centrosome
Thaum lub sijhawm sib faib ntawm tes, centrioles ua lub luag haujlwm tseem ceeb los ntawm kev txiav txim siab lub dav hlau uas muaj kev faib tawm hauv lub cell. Tsis tas li ntawd, centrosomes tsim spindle fibers los txuas nrog cov centromeres ntawm chromosomes.
Dab tsi zoo sib xws ntawm Ribosome thiab Centrosome?
- Ob leeg ribosome thiab centrosome yog cell organelles.
- Ntxiv mus, lawv ua haujlwm tseem ceeb hauv cov hlwb nyob.
Qhov txawv ntawm Ribosome thiab Centrosome yog dab tsi?
Lub ribosome yog qhov chaw tseem ceeb ntawm cov protein synthesis nyob rau hauv ib lub cell thaum lub centrosome yog lub luag hauj lwm rau cell division. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm ribosome thiab centrosome. Tsis tas li ntawd, ribosomes muaj nyob thoob plaws lub cytoplasm ntawm lub cell thaum centrosomes nyob ze ntawm lub nucleus. Yog li, peb tuaj yeem xav txog qhov no kuj yog qhov sib txawv ntawm ribosome thiab centrosome.
Ntxiv mus, qhov sib txawv ntxiv ntawm ribosome thiab centrosome yog tias ribosome muaj ob txoj hauv kev ntawm RNA thiab cov proteins, thaum centrosome muaj ob lub centrioles.
Cov hauv qab no infographic muab cov ntsiab lus ntxiv txog qhov sib txawv ntawm ribosome thiab centrosome.
Summary – Ribosome vs Centrosome
Ribosome thiab centrosome yog ob lub cell organelles tseem ceeb. Ribosome nqa tawm protein synthesis nyob rau hauv ib lub cell. Ntawm qhov tod tes, lub centrosome yog lub luag haujlwm rau kev faib cell ntawm cov tsiaj hlwb. Hauv kev xaus, qhov no yog qhov sib txawv tseem ceeb ntawm ribosome thiab centrosome. Tsis tas li ntawd, ribosome muaj ob txoj hauv kev ntawm RNA thiab cov proteins, thaum centrosome muaj ob lub centrioles. Tsis tas li ntawd, ribosomes tau tawg thoob plaws hauv cytoplasm thaum centrosome pom nyob ze ntawm lub nucleus. Tsis tas li ntawd, ribosomes tshwm sim me me thaum cov centrosomes zoo li lub thoob.
