Endocytosis yog txheej txheem cellular uas cov tshuaj coj mus rau hauv lub cell. Cov khoom yuav tsum tau internalized yog surrounded los ntawm ib cheeb tsam ntawm cell membrane, uas ces buds tawm hauv lub cell los tsim ib tug vesicle uas muaj cov khoom noj.

Yuav ua li cas thaum lub sijhawm endocytosis?

Endocytosis yog cov txheej txheem uas cov hlwb coj cov khoom tawm sab nraud ntawm tes los ntawm kev nkag mus rau hauv lub vesicle. … Endocytosis tshwm sim thaum ib feem ntawm cov cell membrane folds rau ntawm nws tus kheej, encircling extracellular kua thiab ntau yam molecules los yog microorganisms.

Cov ntaub ntawv dab tsi raug txav mus rau thaum lub sijhawm endocytosis?

Endocytosis yog ib hom kev thauj mus los uas txav cov khoom, xws li cov molecules loj, qhov chaw ntawm cov hlwb, thiab txawm tias tag nrho cov hlwb, mus rau hauv lub cell. Muaj ntau qhov sib txawv ntawm endocytosis, tab sis txhua tus muaj cov yam ntxwv sib xws: cov plasma membrane ntawm cov cell invaginates, tsim ib lub hnab tshos nyob ib ncig ntawm lub hom phiaj particle.

Yuav ua li cas rau endocytosis?

Yuav kom muaj qhov endocytosis tshwm sim, cov khoom yuav tsum tau muab ntim rau hauv cov vesicle tsim los ntawm cov cell membrane, los yog plasma membrane… pab thoob plaws los ntawm cov txheej txheem tsis sib haum xeeb (fais fab diffusion), kev thauj mus los (yuav tsum muaj zog), lossis los ntawm endocytosis.

YYuav siv dab tsi hauv endocytosis?

Receptor-mediated endocytosis yog ib hom endocytosis uas receptor proteins ntawm lub xovtooj ntawm tes yog siv los ntes ib lub hom phiaj molecule. Cov receptors, uas yog transmembrane proteins, pawg nyob rau hauv cheeb tsam ntawm lub plasma membrane hu ua coated pits.
