Main. Lub endoplasmic reticulum (ER) yog qhov loj tshaj plaws membrane-bound organelle nyob rau hauv eukaryotic hlwb thiab ua ntau yam tseem ceeb cellular zog, xws li protein synthesis thiab ua, lipid synthesis, thiab calcium (Ca 2 +) cia thiab tso.
Dab tsi yog 3 lub luag haujlwm tseem ceeb ntawm endoplasmic reticulum?
Tus ER yog lub cev loj tshaj plaws hauv lub cell thiab yog qhov chaw loj ntawm protein synthesis thiab thauj, protein folding, lipid thiab steroid synthesis, carbohydrate metabolism thiab calcium cia[1 –7].
Dab tsi yog qhov ua haujlwm ntawm endoplasmic reticulum quizlet?
Lub luag haujlwm ntawm Endoplasmic Reticulum yog dab tsi? Lub Endoplasmic Reticulum thauj cov khoom noj los ntawm ib feem ntawm lub cell mus rau lwm qhov.
plaub lub luag haujlwm tseem ceeb ntawm endoplasmic reticulum yog dab tsi?
Nws ua lub luag haujlwm tseem ceeb hauv tsim khoom, ua, thiab thauj cov protein thiab lipids. Lub ER tsim cov proteins thiab lipids rau nws daim nyias nyias thiab rau ntau lwm yam ntawm tes xws li lysosomes, secretory vesicles, Golgi appatatus, cell membrane, thiab cog cell vacuoles.
Dab tsi yog qhov ua haujlwm ntawm cov menyuam endoplasmic reticulum?
Endoplasmic reticulum yog cov khoom sib sau ntawm cov raj uas ua, pob, thiab thauj cov protein thiab rog. Rough endoplasmic reticulum muaj protein uaribosomes ntawm nws nto, yog li nws pab ua thiab ua cov proteins. Smooth endoplasmic reticulum pab tsim thiab ua cov lipids thiab pab detoxify tshuaj thiab cawv.

Dab tsi yog txoj haujlwm ntawm txoj kev internodal?
Cov kab mob anterior internodal dhau los ntawm qhov sinus node sinus node Lub sinoatrial node (SA node) yog tus qauv myocardial tshwj xeeb uas pib cov hluav taws xob impulses los txhawb kev cog lus, thiab pom nyob rau hauv lub atrial phab ntsa ntawm qhov sib txuas ntawm superior caval leeg thiab sab xis atrium (Mikawa thiab Hurtado, 2007).
Qhov twg endoplasmic reticulum ua ribosomes?
Cov tawv nqaij endoplasmic reticulum muaj nyob rau ntawm nws ribosomes, uas yog me me, puag ncig organelles uas nws ua haujlwm yog los ua cov proteins. YPuas ER ntxhib ua ribosomes? Rough endoplasmic reticulum, (RER), muaj coob tus ribosomes txuas rau sab nrauv ntawm lamella daim nyias nyias.
Cov nroj tsuag puas muaj endoplasmic reticulum?
Lub endoplasmic reticulum (ER) yog ib qho organelle uas muaj zog heev hauv eukaryotic hlwb thiab qhov chaw tsim khoom loj ntawm cov proteins destined rau vacuoles, cov plasma membrane, los yog apoplast hauv nroj tsuag. Pob nroj tsuag thiab tsiaj txhu muaj endoplasmic reticulum?
Puas muaj nyob rau ntawm endoplasmic reticulum thiab synthesizes proteins?
Rough ER nyob tam sim ntawd nyob ib sab ntawm lub cell nucleus, thiab nws daim nyias nyias yog txuas ntxiv nrog rau sab nrauv ntawm lub hnab ntawv nuclear. Cov ribosomes ntawm ntxhib ER tshwj xeeb hauv kev sib txuas ntawm cov proteins uas muaj cov teeb liab sib lawv liag uas coj lawv tshwj xeeb rau ER rau kev ua haujlwm.
Puas yog txoj haujlwm nyuaj ua rau muaj kev puas tsuaj rau txoj haujlwm?
Kev sib tw ua haujlwm tuaj yeem txhawb siab rau cov neeg ua haujlwm Yog tias kev ua haujlwm nyuaj heev uas nws ua tsis tau - lossis yog cov neeg ua haujlwm xav tias lawv tsis muaj kev txawj ntse, peev txheej lossis kev pabcuam kev tswj hwm tsim nyog kom kov yeej cov kev cov nyom - nws tuaj yeem txo lawv txoj kev mob siab rau thiab muaj kev cuam tshuam tsis zoo rau cov neeg ua haujlwm kev coj ncaj ncees.
