Endoplasmic reticulum yog kev sau cov raj uas ua, pob, thiab thauj cov protein thiab cov rog. Ntxhib endoplasmic reticulum muaj protein-ua ribosomes ntawm nws qhov chaw, yog li nws pab tsim thiab txheej txheem cov protein. Du endoplasmic reticulum pab ua thiab txheej txheem lipid thiab pab tshem tawm cov tshuaj thiab dej cawv.
Kuj paub, dab tsi yog qhov ua haujlwm ntawm endoplasmic reticulum?
Kev ua haujlwm. Qhov endoplasmic reticulum ua haujlwm rau ntau txoj haujlwm dav dav, suav nrog kev sib cais cov protein molecules hauv cov hnab hu ua cisternae thiab thauj cov protein sib txuas hauv cov vesicles mus rau Golgi apparatus.
Ib tus kuj tseem yuav nug tau, 3 lub luag haujlwm tseem ceeb ntawm endoplasmic reticulum yog dab tsi? Nws ua lub luag haujlwm tseem ceeb hauv kev tsim khoom, ua tiav, thiab thauj mus los cov protein thiab lipid. ER ua cov transmembrane cov protein thiab lipid rau nws daim nyias nyias thiab ntau lwm yam khoom siv ntawm tes suav nrog lysosomes, cov hlab ntsha zais zis, Golgi appatatus, cov cell membrane, thiab cog cell vacuoles.
Tom qab ntawd, ib tus tseem tuaj yeem nug, qhov endoplasmic reticulum yog dab tsi thiab nws txoj haujlwm yog dab tsi?
Endoplasmic reticulum ( ER ), hauv kev tshawb fawb txog biology, cov txheej txheem txheej txheej tas mus li uas tsim ua ib txheej ntawm cov hnab ntim hauv cov cytoplasm ntawm eukaryotic cells thiab ua haujlwm ntau yam kev ua haujlwm , yog qhov tseem ceeb tshwj xeeb hauv kev sib txuas, sib dhos, hloov kho, thiab thauj cov protein.
Endoplasmic reticulum yooj yim txhais li cas?
Organelle suav nrog kev sib koom ua ke ntawm daim nyias nyias nyob hauv cytoplasm ntawm eukaryotic cells uas yog qhov tseem ceeb hauv kev sib xyaw cov protein thiab quav thiab koom nrog hauv kev thauj cov khoom siv ntawm tes. Cov endoplasmic reticulum tuaj yeem txuas ntxiv nyob rau hauv qhov chaw nrog daim nyias nyias ntawm cov cell nucleus.

Qhov ntxhib endoplasmic reticulum nyob qhov twg?
Rough ER tau pom thoob plaws hauv lub xovtooj tab sis qhov ntom tau siab dua nyob ze cov nucleus thiab cov cuab yeej Golgi. Ribosomes ntawm qhov ntxhib endoplasmic reticulum hu ua 'membrane bound' thiab yog lub luag haujlwm rau kev sib dhos ntawm ntau cov protein. Txoj kev no hu ua kev txhais lus
Dab tsi yog qhov txiaj ntsig ib txwm rau PaO 2 Dab tsi yog qhov txiaj ntsig rau kev txiav txim siab qhov hnyav ntawm hypoxemia?
Zoo li feem ntau qhov kev kho mob ib txwm muaj txiaj ntsig thiab ntau yam, lub ntsiab lus tuaj yeem sib txawv me ntsis, tab sis feem ntau cov ntsiab lus hauv qab no siv: Ua rau me me hypoxemia: PaO2 = 60 txog 79 mmHg. Qhov nruab nrab hypoxemia: PaO2 = 40 txog 59 mmHg. Hypoxemia hnyav: PaO2 <40 mmHg
Dab tsi organelles qhov ntxhib endoplasmic reticulum ua haujlwm nrog?
Lwm organelle hauv lub cell yog endoplasmic reticulum (ER). Thaum lub luag haujlwm ntawm cov tub ntxhais yog ua raws li lub hlwb ntawm tes, ER ua haujlwm raws li kev tsim khoom thiab ntim khoom. Nws ua haujlwm ze nrog Golgi apparatus, ribososmes, mRNA, thiab tRNA
Dab tsi yog lub luag haujlwm tseem ceeb ntawm du endoplasmic reticulum ER?
Nws lub luag haujlwm tseem ceeb yog kev sib txuas ntawm cov lipid, cov tshuaj steroid, kev tshem tawm cov teeb meem metabolic los ntawm cov khoom lag luam thiab kev khaws cia thiab cov metabolism hauv calcium ions hauv lub cell. ER du yog qhov txawv ntawm lwm qhov ntawm endoplasmic reticulum los ntawm qhov tsis muaj daim nyias nyias-khi ribosomes
Dab tsi yog qhov ua haujlwm ntawm endoplasmic reticulum du?
Nws lub luag haujlwm tseem ceeb yog kev sib txuas ntawm cov lipid, cov tshuaj steroid, kev tshem tawm cov teeb meem metabolic los ntawm cov khoom lag luam thiab kev khaws cia thiab cov metabolism hauv calcium ions hauv lub cell. ER du yog qhov txawv ntawm lwm qhov ntawm endoplasmic reticulum los ntawm qhov tsis muaj daim nyias nyias-khi ribosomes
