Endocytosis yog txheej txheem ntawm kev ntes cov khoom lossis cov khoom me me sab nraum lub cell los ntawm kev nkag mus rau nws nrog cov cell membrane, thiab nqa nws mus rau hauv lub cell. Exocytosis piav qhia cov txheej txheem ntawm vesicles sib xyaw nrog cov ntshav ntshav thiab tso tawm lawv cov ntsiab lus mus rau sab nraud ntawm tes.
Zoo ib yam tuaj yeem nug, dab tsi yog endocytosis hauv biology?
Endocytosis yog txheej txheem ntawm kev thauj cov molecules mus rau hauv lub cell los ntawm kev nkag mus nrog nws cov membrane. Endocytosis thiab exocytosis tau siv los ntawm txhua lub cell thauj cov molecules uas tsis tuaj yeem hla ntawm daim nyias nyias.
Qhov thib ob, 3 yam mob endocytosis yog dab tsi? Muaj peb hom kab mob endocytosis: phagocytosis , pinocytosis , thiab receptor-mediated endocytosis. Hauv phagocytosis lossis "kev noj zaub mov ntawm tes," lub cell cov ntshav ntshav nyob ib puag ncig macromolecule lossis txawm tias tag nrho ntawm tes los ntawm ib puag ncig sab nraud thiab tawm mus ua cov zaub mov vacuole lossis phagosome.
endocytosis txawv li cas ntawm exocytosis?
Sib txawv yog: Endocytosis nqa cov ntaub ntawv mus rau sab hauv ntawm tes thaum exo coj lawv tawm. Exoocytosis muaj lub vesicle raug tsim nyob rau hauv lub tshuab golgi uas tom qab ntawd fuses nrog daim nyias nyias, thaum endo muaj lub vesicle. Exocytosis nce qhov loj ntawm cov cell membrane thaum endo ua qhov txawv.
Tus endocytosis ua dab tsi?
Endocytosis yog ib hom kev thauj mus los uas txav cov khoom, xws li cov molecules loj, ib feem ntawm cov cell, thiab txawm tias tag nrho cov cell, mus rau hauv ntawm tes . Muaj ntau qhov kev hloov pauv ntawm endocytosis, tab sis txhua tus qhia ib tus yam ntxwv sib xws: cov ntshav ntshav ntawm cov ntawm tes invaginates, tsim ib lub hnab nyob ib ncig ntawm lub hom phiaj.

Dab tsi yog glycoprotein dab tsi yog ib qho ntawm kev siv glycoproteins?
Glycoproteins yog cov protein uas muaj cov oligosaccharide saw (glycans) covalently txuas nrog cov amino acid sab-saw. Glycoproteins kuj tseem yog ib qho tseem ceeb ua ke ntawm cov protein, uas lawv ua lub luag haujlwm hauv kev sib cuam tshuam ntawm tes -cell
Dab tsi yog cov khoom siv hauv lub cev zom zaub mov thiab lawv lub luag haujlwm yog dab tsi?
Cov khoom siv hauv lub cev zom zaub mov suav nrog cov hniav, tus nplaig, cov qog ua kua qaub, daim siab, lub zais zis, thiab txiav txiav. Txhawm rau ua tiav lub hom phiaj ntawm kev muab lub zog thiab khoom noj khoom haus rau lub cev, rau lub luag haujlwm tseem ceeb nyob hauv cov txheej txheem zom zaub mov: nqos. Kev zais
Dab tsi yog qhov kev nkag siab tsis tu ncua thiab dab tsi yog qhov loj me me qhov ntev xim tsis tu ncua zoo li qub)?
Kev nkag siab tsis tu ncua, tseem hu ua qhov tsis sib xws, lossis qhov tshwm sim tsis tu ncua, kev nyiam tsiaj thiab tib neeg kom pom cov khoom paub zoo li muaj tus qauv zoo, qhov loj me, xim, lossis qhov chaw tsis hais txog kev hloov pauv ntawm lub kaum sab xis ntawm kev xav, nrug deb, lossis teeb pom kev zoo
Lub cev tseem ceeb ntawm lub plab zom mov yog dab tsi thiab lawv lub luag haujlwm yog dab tsi?
Cov khoom siv hauv lub cev zom zaub mov suav nrog cov hniav, tus nplaig, cov qog ua kua qaub, daim siab, lub zais zis, thiab txiav txiav. Txhawm rau ua tiav lub hom phiaj ntawm kev muab lub zog thiab khoom noj khoom haus rau lub cev, rau lub luag haujlwm tseem ceeb nyob hauv cov txheej txheem zom zaub mov: nqos. Kev zais. Sib tov thiab txav mus los. Digestion. Kev nqus. Kev tshem tawm
Lub cell siv exocytosis li cas los tso cov ntsiab lus ntawm vesicle sab nraum lub cell?
Hauv exocytosis, cov ntaub ntawv raug xa tawm ntawm lub xovtooj ntawm cov vesicles zais cia. Hauv txheej txheem no, theGolgi complex pob macromolecules rau hauv cov khoom thauj uas mus rau thiab fuse nrog cov ntshav ntshav
