| Dab tsi ntawm cov hauv qab no muaj lub network ntawm intracellular membranes nrog txuas ribosomes? | Rough Endoplasmic reticulum |
| Kev hloov kho tshiab lossis hloov kho ntawm cov cell membrane yog afunction ntawm | Golgi apparatus |
| Organelles uas zom fatty acids thiab hydrogen peroxideare | peroxisomes |
Xav txog qhov no, dab tsi muaj lub network ntawm cov kab mob hauv lub cev koom nrog hauv kev tsim cov tshuaj hormones steroid thiab carbohydrates?
Cov proteins uas ua los ntawm qhov ntxhib endoplasmic reticulum yog siv rau sab nraud ntawm tes. Kev ua haujlwm ntawm cov endoplasmicreticulum du muaj xws li synthesis ntawm carbohydrates , lipids, thiab steroid cov tshuaj hormones ; detoxification ntawm cov tshuaj thiab tshuaj lom; thiab cia cov calcium ions.
Tom qab ntawd, lo lus nug yog, thaum qhib lysosomes ua haujlwm li cas? Lysosomes digest cov ntaub ntawv coj mus rau hauv lub cell thiab recycle cov ntaub ntawv intracellular. Kauj Ruam Ib qho qhia pom tias nkag mus rau cov khoom noj vacuole los ntawm cov plasma membrane, ib qho txheej txheem hu ua endocytosis.
Tsis tas li lo lus nug yog, qhov twg yog cov khoom ntawm ribosomes tsim?
Hauv cov kab mob kab mob, cov ribosomes yog ua ke nyob rau hauv lub cytoplasm los ntawm transcription ofmultiple ribosome gene operons. Nyob rau hauv eukaryotes, cov txheej txheem muab tso rau hauv lub cell cytoplasm thiab nyob rau hauv lub nucleolus, uas yog ib cheeb tsam nyob rau hauv lub cell nucleus.
Dab tsi feem ntau muaj tsib lossis rau lub tiaj membranous discs hu ua Cisternae?
Golgi apparatus feem ntau muaj tsib los yog sixflattened membranous discs hu ua cisternae.

Puas yog nws muaj tseeb tias nyob rau hauv kev thauj mus los ntawm kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog?
Hauv kev thauj mus los passive, kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog. _ Muaj tseeb_ 5. Endocytosis yog ib txoj kev uas ib lub cell membrane nyob ib puag ncig thiab siv cov khoom los ntawm ib puag ncig. Ib daim nyias nyias uas tso cai rau qee cov ntaub ntawv dhau los qhia txog kev xaiv permeability
Puas yog glycerol xav tau daim nyias nyias nyias kom hla daim nyias nyias?
Glycerol yog lipid soluble yog li nws diffuses los ntawm yooj yim diffusion ncaj qha los ntawm lub cell membrane thaum cov piam thaj yog ib tug polar molecule yog li nws diffuses los ntawm kev yooj yim diffusion uas txhais tau hais tias nws xav tau ib tug channel protein ua hauj lwm thiab qhov no txhais tau tias thaj chaw saum npoo rau cov piam thaj kom nkag mus yog tsawg dua. tshaj ib qho rau glycerol
Yuav ua li cas yog lub hom phiaj ntawm carrier proteins nyob rau hauv daim nyias nyias?
Muaj nuj nqi. Cov cab kuj muaj protein ntau pab txhawb kev nthuav tawm ntawm cov molecules hla lub cell membrane. Cov protein yog imbedded nyob rau hauv lub cell membrane thiab npog tag nrho cov membrane. Qhov no yog qhov tseem ceeb vim tias tus neeg nqa khoom yuav tsum thauj cov molecule hauv thiab tawm ntawm lub cell
Dab tsi yog ib qho laj thawj uas ib lub xovtooj yuav tsum tau tswj cov dej ntws hla ntawm daim nyias nyias?
Dab tsi yog ib qho laj thawj uas lub cell yuav tsum tswj cov flowacross daim nyias nyias? Lub nucleus yuav tsum coj mus rau hauv DNA. Lub cell xav tau cov pa roj carbon dioxide ua lub zog. Cov cytoplasmneeds coj cov organelles
Yuav ua li cas sib txawv ntawm cov molecules dhau los ntawm daim nyias nyias?
Lub plasma membrane yog selectively permeable; hydrophobic molecules thiab me me polar molecules tuaj yeem cuam tshuam los ntawm lipid txheej, tab sis ions thiab cov polar loj molecules tsis tuaj yeem. Integral membrane proteins pab kom ions thiab cov polar loj molecules hla los ntawm daim nyias nyias los ntawm passive los yog active thauj
