Endoplasmic reticulum nrog txuas ribosomes hu ua rough ER. Nws zoo nkaus li bumpy nyob rau hauv lub microscope. Cov ribosomes uas txuas nrog ua cov proteins uas yuav siv rau hauv lub cell thiab cov proteins uas ua rau xa tawm ntawm lub cell. Tseem muaj cov ribosomes txuas rau lub hnab ntawv nuclear.
Cov proteins twg yog tsim los ntawm khi ribosomes?
Cov protein uas ua haujlwm hauv cov kab ke endomembrane (xws li lysosomal enzymes) lossis cov uas yog destined rau secretion los ntawm cell (xws li insulin) yog synthesized los ntawm khi ribosomes.
Cov proteins uas tsim los ntawm cov ribosomes txuas mus rau qhov twg?
Txuas ribosomes yog lub luag haujlwm tsim cov proteins uas yuav yog ib feem ntawm daim nyias nyias los yog uas yuav muab khaws cia rau hauv chav hu ua vesicles. Bound ribosomes kuj txhais mRNA rau cov proteins uas yuav txav mus rau sab nraud ntawm tes.
ribosomes txuas rau dab tsi?
Lub ribosome uas yog synthesizing cov protein yog txuas ncaj qha mus rau the ER membrane. Cov membrane-bound ribosomes coated nto ntawm ER, tsim cov cheeb tsam hu ua ntxhib endoplasmic reticulum, los yog ntxhib ER (Daim duab 12-36A).
Qhov txawv ntawm qhov pub dawb thiab txuas ribosomes yog dab tsi?
Free vs Attached Ribosomes
Dawb ribosomes yog cov organelles me nyob hauv cytoplasm. Txuas ribosomes yog cov organelles me me uas txuas rau saum npoo ntawm endoplasmic reticulum. Dawb ribosomes tsis txuas rau ib qho qauv ntawm tes.
