Reticulum Endoplasmic: dhismaha iyo shaqada

reticulum Endoplasmic - organelle khasab ah unugyada eukaryotic. Waxaa laga helaa unugyada dhirta, xayawaanka iyo bini'aadanka. Shaqada qayb this unugga ee waa kala duwan iyo waxaa badanaa la xidhiidha Avv, badalaada iyo gaadiidka xeryahooda organic.

Waayo, markii ugu horeysay reticulum ku endoplasmic la ogaaday in 1945. saynisyahan American K. Porter arkay iyada oo leh mid ka mid ah microscopes horeysay korontada. Tan iyo waqti in, waxay bilaabeen in ay cilmi-baarista firfircoon.

In gacanta, waxaa jira laba nooc oo organelle this:

• granular ama reticulum endoplasmic xunxunna (ribosomes hannaanka daboolay).
• Of reticulum endoplasmic ku siman ama siman.

nooc kasta oo reticulum leeyahay muuqaalada qaar ka mid ah oo u qabata shaqo ahaanba ka duwan tahay. Bal aynu eegno iyaga at si faahfaahsan.

reticulum endoplasmic Granular: qaab-dhismeedka. organelle Tani waa habka taangi, kiishka iyo tubules. derbiyadeeda ka kooban yahay xuub bilipidnoy. width ee saabka u dhaxayn kartaa 20 nm dhowr micrometers - oo dhan ku xiran yihiin waxqabadka ee unugyada secretory.

Ha ah unugyada khaas yar, oo waxaa lagu gartaa heerka hoose shiid, EPS soo gudbiyey leh oo kaliya dhowr ah taangiyada kala firdhiyey. Inside gacanta, kaas oo si firfircoon waa synthesize protein reticulum endoplasmic ka kooban yahay hannaanka ka mid ah taangiyada iyo nidaamka tubules jahaysteen.

Sida caadiga ah, EPM granular dhex xuubka embriyaha xiran yahay baqshadda nuclear - sidan lagu geeddi Avv adag oo u taagoo protein gaadiidka.

reticulum endoplasmic Granular: shaqooyinka. Sida hore u soo sheegnay, dusha oo dhan ay XPS cytoplasm daboolay by ribosomes, kaas oo lagu yaqaan in ay ku lug Avv borotiinka. EPS - meel ereygu iyo gaadiidka xeryahooda protein.

organelle Tani waxay masuul ka tahay ereygu wuxuu ahaa ee xuub cytoplasmic ah borotiinada muhiim. Laakiin xaaladaha inta ugu badan ay u taagoo protein dheeraad ah via kiishka xuub waxaa loo qaadaa ah qalab Golgi, meesha ay joogaan badalaada iyo qaybinta dheeraad ah baahida unugyada, siday u kala horreeyaan, iyo unugyada.

Intaa waxaa dheer, godadka dhici taangiyada EPS iyo qaar ka mid ah isbedel ku borotiinka - tus, goysiga ah qayb carbohydrate. Halkan, by xulkii of dhagaxyada ah secretory ballaaran loo sameeyay.

network endoplasmic siman, dhismaha iyo shaqada. Dhismaha EPS siman ayaa kala duwan qaar ka mid ah. Tusaale ahaan, organelle this ka kooban yahay oo kaliya ee taangiyada iyo waxa uu leeyahay nidaam lahayn tubules. Kaxeynayo EPS sida, sida caadiga ah, waa yar yar, laakiin width ah ee taangiga, on lid ku ah, ka badan.

The reticulum endoplasmic siman oo aan la xiriirin ereygu wuxuu ka kooban borotiinka laakiin fuliya tiro ka mid ah hawlaha si siman muhiim ah. Tusaale ahaan, halkan waa duubis ah ee hormoonnada steroid ee dadka iyo vertebrates oo dhan. Taasi waa sababta mugga EPS siman ee unugyada adrenal waa wax weyn.

In unugyada beerka EPS soo saarta ee falgalka loo baahan yahay ku lug-shiid carbohydrate, kuwaas oo kala daatay ee glycogen. Waxaa kale oo la og yahay in unugyada beerka ayaa ka mas'uul ah dhexdhexaadnimada ee sunta. In taangiyada organelle this ereygu wuxuu ahaa ee qayb ka hydrophilic kaas oo markaas ku lifaaqan Britain a sun kordhisaa milmi dhiigga iyo kaadida. Waxa xiiso leh in in hepatocytes, taas oo si joogto ah sarkhaansan yihiin sunta (sunta, khamriga) ku dhici, ku dhowaad dhammaan unugyada degan taangiyada si adag u dhaxeyso EPS siman.

In unugyada muruqa, waxaa jira nooc gaar ah EPS siman - reticulum sarcoplasmic. Waxay u dhaqmo sida nidaminayo saldhig calcium ah sidaas maaraysa waxqabad iyo unugyada nasasiiyay.

Sida laga arki karo, EPS hawlaha kala duwan yihiin oo aad u muhiim u ah hawlaha caadiga ah ee unugyada caafimaadka qaba.
