Lub nucleus muaj cov ntaub ntawv genetic information (DNA) onspecial strands hu ua chromosomes. Muaj nuj nqi - Lub nucleus yog " tswj chaw "ntawm cell , rau cell metabolism thiab kev loj hlob. Cov kab mob hauv qab no muaj nyob hauv cov nroj tsuag thiab tsiaj txhu CELLS.
Tsuas yog li ntawd, qhov chaw tswj kev ua haujlwm ntawm tes yog dab tsi?
Sab hauv daim nyias nyias, hu ua cristae muab ntau qhov chaw nthuav tawm cov kua dej (matrix) uas muaj cov enzymes themetabolic uas muab lub zog rau cellular muaj nuj nqi. Cov tswj chaw rau kev ua haujlwm ntawm tes , muaj tag nrho cov khoom siv caj ces. Nyob ib ncig ntawm lub nucleus thiab cais nws tsim nws cytosol.
Qhov thib ob, lub organelle twg yog qhov chaw tswj hwm? nucleus
Ib yam li ntawd, tib neeg nug, qhov twg ntawm lub xovtooj ntawm tes tswj cov haujlwm ntawm tes?
Txhua tus ntawm koj hlwb muaj ib tug thawj coj, ib yam nkaus: lub nucleus. Qhov no tswj center khiav cov yeeb yam, qhia cov cell los ua cov haujlwm tseem ceeb, xws li kev loj hlob, kev loj hlob thiab kev faib tawm. Feem ntau ntawm koj lub cev cov khoom siv caj ces - nws cov deoxyribonucleic acid, lossis DNA - nyob rau hauv lub nucleus.
Lub luag haujlwm ntawm cov khoom ntawm tes yog dab tsi?
Qib 7 - Cell Parts and Functions
| A | B |
|---|---|
| vacuole | qhov chaw cia rau dej, pov tseg, & lwm yam khoom siv cellular |
| endoplasmic reticulum | qhov chaw uas cov ntaub ntawv raug ua tiav thiab tsiv mus nyob rau hauv lub cell |
| cov ribosomes | tsim cov proteins hauv lub cell |
| cov lysosomes | muaj cov tshuaj digestive uas pab zom cov zaub mov |

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Vim li cas lub xov tooj ntawm tes suav hais tias yog cov qauv tsim thiab kev ua haujlwm ntawm txhua yam kabmob?
Cell hu ua structural unit vim lub cev ntawm tag nrho cov kab mob yog tsim los ntawm cov hlwb. Nws yog lub luag haujlwm ntawm lub neej vim tias tag nrho cov haujlwm ntawm lub cev (physiological, biochemical. genetic thiab lwm yam haujlwm) yog ua los ntawm cov hlwb
Lub organelle twg ua haujlwm raws li qhov chaw xa ntawv ntawm lub xov tooj ntawm tes txheeb cov proteins thiab xa lawv mus rau lawv qhov chaw xav tau sab hauv lossis sab nraud ntawm tes?
Golgi Hais txog qhov no, dab tsi organelle yog lub luag haujlwm rau kev thauj mus los? endoplasmic reticulum (ER Qhov thib ob, cov proteins txav mus los ntawm lub cell li cas? Cov proteins txav mus los endomembrane system thiab raug xa tawm los ntawm lub ntsej muag trans ntawm Golgi apparatus nyob rau hauv thauj vesicles uas txav mus los cytoplasm thiab tom qab ntawd fuse nrog plasma membrane tso tawm protein ntau mus rau sab nraum lub cell .
Dab tsi cuam tshuam rau kev tshem cov choj ntsev muaj rau kev ua haujlwm ntawm txhua lub xov tooj ntawm tes electrochemical?
Yog tsis muaj ntsev choj, cov tshuaj nyob rau hauv lub anode compartment yuav ua tau zoo them thiab cov tshuaj nyob rau hauv lub cathode compartment yuav ua tsis zoo nqi, vim hais tias ntawm tus nqi imbalance, lub electrode cov tshuaj tiv thaiv yuav sai sai los mus rau ib tug nres, yog li ntawd nws yuav pab kom tswj tau qhov khiav. los ntawm electrons
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
