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).

Myth: Ib tug dab tshos tsis yog neeg ncaj ncees yog tiasnws haum yog. Fact: Tu siab, qhov no yog ib lo lus tsis tseeb uas tau raug perpetuated los ntawm aversive trainers. Txawm hais tias haum rau lub caj dab kom zoo khawb rau hauv cov tawv nqaij rhiab nyob ib ncig ntawm lub caj dab, uas ua rau muaj kev puas tsuaj loj rau cov thyroid, esophagus, thiab trachea.
Dab tsi yog kev xav ntawm autonomists dab tsi yog qhov kev xav ntawm kev zoo nkauj ntawm kev coj ncaj ncees?
Kev lig kev cai, muaj ob txoj haujlwm tawm tsam kev xav txog kev coj ua raws li kev cai lij choj ntawm kev ntsuas kev ncaj ncees ntawm kev kos duab: 'kev coj ncaj ncees kev ncaj ncees Ethics lossis kev coj ncaj ncees yog ib ceg ntawm kev xav uas "
Dab tsi ntawm cov hauv qab no yog qhov tshwm sim ntawm kev sib ntaus sib tua ntawm lub pas dej brandywine?
Cov txiaj ntsig ntawm Kev Sib Tw ntawm Brandywine Creek yog dab tsi? Washington tsuas yog sim ncua kev ntes Philadelphia kom nws ua tiav li no. Cov tub rog Asmeskas tsis tau poob siab ntau thiab lawv tau khiav tawm ntawm British. Washington tseem tuaj yeem kawm los ntawm nws qhov yuam kev ntawm kev tso nws txoj cai sab xis qhib.
Puas yog cov dab dab dab dab dab dab tau them?
OHL cov neeg ua si tsis tau nyiaj hli, vim lawv tsis raug lees paub tias yog cov neeg ua haujlwm raws li Txoj Cai Kev Ua Haujlwm. Txawm li cas los xij, lawv suav nrog cov txiaj ntsig xws li nyiaj rov qab txhua xyoo, tag nrho cov nqi kawm ntawv them, thiab daim pib pub dawb.
Dab tsi organelle repackages proteins?
Golgi complex Golgi complex Lub Golgi apparatus, los yog Golgi complex, ua haujlwm raws li lub Hoobkas uas cov protein tau txais los ntawm ER tau ua tiav thiab txheeb xyuas kev thauj mus los rau lawv qhov chaw kawg: lysosomes, plasma membrane, los yog secretion.
