Exocytosis ua haujlwm ntau yam tseem ceeb vim nws tso cai rau cov hlwb kom tso cov khoom pov tseg thiab cov molecules, xws li cov tshuaj hormones thiab cov proteins. … Tsis tas li ntawd, exocytosis yog siv los tsim kho cov cell membrane los ntawm kev sib xyaw lipids thiab cov proteins tshem tawm los ntawm endocytosis rov qab mus rau hauv daim nyias nyias.
Lub hom phiaj ntawm exocytosis yog dab tsi?
Exocytosis yog cov txheej txheem siv hluav taws xob uas tshem tawm cov hlwv zais zis uas muaj nanoparticles (los yog lwm yam tshuaj) tawm ntawm cov cell membranes mus rau qhov chaw extracellularFeem ntau, cov membrane-bound vesicles muaj. Soluble proteins, membrane proteins, thiab lipids yuav secreted rau extracellular ib puag ncig.
Vim li cas endocytosis thiab exocytosis tseem ceeb?
Endocytosis thiab exocytosis yog cov txheej txheem tseem ceeb rau kev coj cov tshuaj mus rau hauv thiab tawm ntawm lub cell. Cells siv exocytosis los tso cov proteins. … Receptor-mediated endocytosis yog ib qho tseem ceeb uas lub cev siv los tshem cov roj cholesterol los ntawm cov hlab ntsha.
Vim li cas endocytosis tseem ceeb?
Endocytosis ua kom tau txais cov as-ham thiab pab tswj kev muaj pes tsawg leeg ntawm cov plasma membrane. Cov txheej txheem yog qhov tseem ceeb rau kev tswj hwm ntawm cov cellular loj xws li kev nthuav qhia antigen lossis intracellular signaling cascades.
Rau ob hom cell twg yog qhov tseem ceeb tshwj xeeb tshaj yog exocytosis?
Exocytosis yog cov txheej txheem uas cov ntsiab lus ntawm cov khoom zais cia raug tso tawm thoob plaws plasma membrane. … Txawm hais tias qhov nce hauv intracellular Ca2+ ua rau cov ntsiab lus vesicle tso tawm hauv ntau hom cell, qhov nce hauv cAMP tseem ceeb dua rau exocytosis hauv qog qaub ncaug, pituitary hlwb, thiab pancreatic β hlwb
