Protein synthesis yog ua tiav los ntawm tus txheej txheem hu ua translation. Tom qab DNA tau sau rau hauv tus xa xov RNA (mRNA) molecule thaum lub sijhawm sau ntawv, mRNA yuav tsum tau muab txhais ua cov protein. Hauv kev txhais lus, mRNA nrog rau kev hloov RNA (tRNA) thiab ribosomes ua haujlwm ua ke los tsim cov protein.
Yuav ua li cas cov proteins thauj los ntawm lub xovtooj tom qab lawv raug tsim tawm?
Yog li ntawd, cov membrane lipids thiab cov proteins uas yog synthesized hauv ER yuav tsum tau thauj mus los ntawm network mus rau lawv qhov chaw kawg hauv daim nyias nyias vesicles. … Thaum lub xovtooj taw qhia los ntawm lub xovtooj, cov hlwv no fuse nrog cov plasma membrane thiab tso lawv cov ntsiab lus mus rau hauv qhov chaw ntxiv.
Yuav ua li cas rau cov proteins thaum lawv raug tsim tawm?
Tom qab raug tsim los, cov protein yuav nqa hauv lub hlwv los ntawm RER mus rau cis ntsej muag ntawm Golgi (sab rau sab hauv ntawm tes). Raws li cov protein txav los ntawm Golgi, nws tuaj yeem hloov kho.
Y Yuav ua li cas cov proteins tuaj yeem ua ke?
Protein synthesis yog txheej txheem uas cov hlwb ua cov protein. Nws tshwm sim nyob rau hauv ob theem: transcription thiab translation. … Kev txhais lus tshwm sim ntawm ribosome, uas muaj rRNA thiab cov proteins. Hauv kev txhais lus, cov lus qhia hauv mRNA tau nyeem, thiab tRNA coj qhov tseeb ntawm cov amino acids mus rau ribosome.
cov proteins thauj li cas?
Los ntawm endoplasmic reticulum, cov proteins raug thauj hauv vesicles mus rau Golgi apparatus, qhov uas lawv tau ua tiav ntxiv thiab txheeb rau kev thauj mus rau lysosomes, plasma membrane, lossis tso tawm los ntawm cov cell.
