Qhov sib txawv tseem ceeb ntawm kev thauj cov hlwv thiab cov hlwv zais cia yog qhov thauj cov hlwv ua kom yooj yim rau kev txav ntawm cov molecules hauv cov hlwb thaum cov hlwv zais zis tawm cov khoom tawm ntawm lub cell.

Ib lub vesicle yog ib qho qauv me me hauv lub cell. Nws yog tsim los ntawm cov kua lipid bilayer. Lub membrane uas kaw lub vesicle kuj yog ib theem lamellar uas zoo ib yam li cov plasma membrane. Qhov chaw hauv lub vesicle tuaj yeem sib txawv ntawm cytosol. Qhov chaw no tuaj yeem ua ntau yam kev ua haujlwm hauv metabolic xws li kev thauj mus los thiab khaws cov molecules. Muaj ntau hom vesicles hauv cov hlwb: thauj vesicles, secretory vesicles, vacuoles, lysosomes, peroxisomes, thiab extracellular vesicles.

Cov Tsheb Thauj Mus Los yog dab tsi?

Kev thauj vesicles txav molecules hauv cov hlwb. Piv txwv li, lawv tuaj yeem txav cov molecules zoo li cov proteins los ntawm qhov ntxhib endoplasmic reticulum mus rau Golgi apparatus. Membrane-bound thiab secreted proteins feem ntau yog tsim los ntawm ribosomes pom nyob rau hauv qhov ntxhib endoplasmic reticulum. Feem ntau ntawm cov proteins no paub tab hauv Golgi apparatus ua ntej tsiv mus rau lawv qhov chaw kawg, uas tej zaum yuav yog lysosomes, peroxisomes, lossis sab nraud ntawm tes. Cov proteins no taug kev hauv lub cell sab hauv ntawm lub cev thauj khoom.

Daim duab 01: Tsheb thauj mus los

Lub Golgi apparatus txheeb xyuas hom kev thauj mus los, ces coj lawv mus rau qhov chaw lawv xav tau. Qee cov proteins hauv lub cev thauj khoom tuaj yeem yog cov protein xws li cov tshuaj tiv thaiv. Golgi apparatus yuav ntim lawv mus rau hauv secretory vesicles kom tso tawm sab nraum lub cell mus tua cov kab mob. Vim yog cov laj thawj saum toj no, qee cov kws tshawb fawb xa mus rau Golgi apparatus ua lub cell "chaw xa ntawv." Thauj vesicles sawv cev tsis yog tsuas yog cov cab kuj rau kev sib pauv ntawm cov khoom soluble ntawm lub cell compartments tab sis kuj yog ib txoj hauv kev zoo ntawm kev txuas ntxiv rov tsim cov cellular membranes los ntawm vesicle-membrane fusions thiab fissions.

Dab tsi yog Secretory Vesicles?

Secretory vesicles tshem tawm cov molecules tawm ntawm lub cell. Feem ntau, secretory vesicles muaj cov ntaub ntawv uas yuav tsum tau tawm ntawm lub cell. Cov hlwb muaj ntau yam vim li cas rau cov khoom tawm. Ib qho laj thawj yog muab pov tseg. Lwm qhov laj thawj yog txuam nrog kev ua haujlwm ntawm tes. Hauv cov kab mob loj dua, qee lub hlwb tau tshwj xeeb los tsim qee yam tshuaj. Cov tshuaj no yog khaws cia rau hauv secretory vesicles thiab tso tawm thaum xav tau. Muaj ob hom secretory vesicles: synaptic vesicles thiab vesicles nyob rau hauv cov ntaub so ntswg endocrine.

Daim duab 02: Secretory Vesicle

Synaptic vesicles nyob ntawm presynaptic terminals nyob rau hauv cov neurons thiab khaws cov neurotransmitters. Hauv cov tsiaj endocrine cov ntaub so ntswg, lawv muaj vesicles uas muaj cov tshuaj hormones uas yuav tsum tau tso rau hauv cov hlab ntsha. Tsis tas li ntawd, secretory vesicles tuav cov enzymes uas siv los ua cov phab ntsa cell ntawm cov nroj tsuag, protists, fungi, kab mob, thiab archaea, nrog rau cov extracellular matrix ntawm cov tsiaj hlwb.

Dab tsi yog qhov zoo sib xws ntawm Tsheb thauj mus los thiab cov zais zais zais zais?

  • Kev thauj cov vesicles thiab secretory vesicles yog ob hom vesicles nyob rau hauv lub cell.
  • Ob lub vesicles muaj cov qauv me me.
  • Ob lub hlwv muaj cov kua dej ntim los ntawm lipid bilayer.
  • Cov vesicles no ua haujlwm tseem ceeb hauv cov kab mob.
  • Lawv ua haujlwm ua ke thaum tshem tawm cov kab mob.

Dab tsi yog qhov txawv ntawm Thauj Vesicles thiab Secretory Vesicles?

Thauj vesicles txav molecules nyob rau hauv lub hlwb, thaum secretory vesicles excrete molecules tawm ntawm lub cell. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev thauj vesicles thiab secretory vesicles. Tsis tas li ntawd, thauj vesicles ua haujlwm nyob rau hauv lub cell, thaum secretory vesicles ua hauj lwm sab nraum lub cell.

Cov hauv qab no qhia txog qhov sib txawv ntawm kev thauj vesicles thiab secretory vesicles hauv daim ntawv tabular rau ib sab ntawm kev sib piv.

Summary – Thauj Vesicles vs Secretory Vesicles

Thauj vesicles thiab secretory vesicles yog ob hom vesicles hauv lub cell. Thauj vesicles txav molecules nyob rau hauv lub hlwb, thaum secretory vesicles excrete molecules tawm ntawm lub cell. Yog li, qhov no qhia txog qhov sib txawv ntawm kev thauj vesicles thiab secretory vesicles.
