Lub endoplasmic reticulum (ER) yog ib qho membranous organelle uas koom ib feem ntawm nws daim nyias nyias nrog cov nucleus. Qee feem ntawm ER, hu ua ntxhib ER ntxhib ER Cov ribosomes ntawm ntxhib ER tshwj xeeb hauv kev sib txuas ntawm cov proteins uas muaj cov teeb liab uasqhia lawv tshwj xeeb rau ER rau kev ua haujlwm. https://www.britannica.com › science › endoplasmic-reticulum

yog studded nrog ribosomesthiab koom nrog kev tsim cov protein.
Cov proteins ua ke nyob qhov twg?
Ribosomes yog qhov chaw hauv lub xovtooj ntawm tes uas muaj protein ntau synthesis. Cells muaj ntau ribosomes, thiab tus naj npawb tseeb nyob ntawm seb lub cell twg yog nyob rau hauv synthesizing proteins.
Yuav ua li cas 3 organelles koom nrog protein synthesis?
Dab tsi yog daim ntawv teev cov organelles uas koom nrog cov protein synthesis? Nucleus muaj cov lus qhia ua cov protein; Nucleolus ua rau ribosomes; Ribosomes ua cov protein; ER thauj cov proteins hauv cell; Golgi ntim cov proteins uas tuaj yeem xa tawm los ntawm cov cell membrane.
Dab tsi yog ob kauj ruam ntawm kev tsim cov protein?
Protein synthesis yog txheej txheem uas cov hlwb ua cov protein. Nws tshwm sim nyob rau hauv ob theem: transcription thiab translation. Transcription yog kev hloov ntawm cov lus qhia genetic hauvDNA rau mRNA nyob rau hauv lub nucleus. Nws suav nrog peb kauj ruam: pib, elongation, thiab xaus.
Yuav ua li cas yog qhov kev txiav txim ntawm organelles hauv cov protein synthesis?
Proteins destined kom secreted txav mus los ntawm secretory txoj kev raws li nram no: rough ER → ER-rau-Golgi thauj vesicles → Golgi cisternae → secretory los yog thauj vesicles → cell nto (exocytosis) (saib daim duab 17-13).
