Golgi rarahaneng

Golgi rarahaneng ile ha sibolloa ke Kamillo Goldzhi ka ka 1898. sebopeho sena se teng ka cytoplasm ya hoo e batlang e tsohle eukaryotic (phelang dikarolo e phahameng) lisele tse, haholo-holo secretory lisele tse ka liphoofolo.

Golgi rarahaneng. Sebopeho.

Sebopeho ke spongebob tsa pantshisi-tse mekotla lera la. Ba bitsoa liliba. spongebob ena ea mekotla e amanang le tsamaiso ea vesicles (e bua Golgi). tswelela pele le hlaha sebopeho sa e ncha vesicles ditanka logan hore lithunthung ho tloha reticulum endoplasmic (cavities marangrang) ho tswa ho e mong ka mekgobo qetellong ea mekotla. From le nonofo ya mmele e mong ka ho feletseng 'me bubble qhala hape qetellong tšoanang tsa spongebob ho mahlakoreng ka hare la tanka. Ka tsela eo ho na le mokhatlo oa butle-butle litanka tse maralla ho lehlakoreng le ka hare ho tloha lehlakoreng le ka ntle.

Sebopeho tanka le hlaha le nonofo ya mmele ea liprotheine reretsoe ho secretion liprotheine transmembrane tsa lero la mali lera liprotheine tsa lysosomes le ba bang. Ripening mahlahana a susumelletseha sequentially Tank organelles. Ka ho na le phutha ho qetela ea liprotheine le diphetolo tsa bona - phosphorylation le glycosylation.

lisele tse dimela di tšoauoa ka nomoro ea dictyosomes motho (mekgobo). Ka lisele tse phoofolo atisa ho ba le ka mekgobo multiple amanang methapo kapa spongebob kgolo.

Sethusathuto (rarahaneng) Golgi na le likarolo tse ka sehloohong a mane: ho ranole-Golgi marangrang, didirisiwa tse cis-Golgi, ho ranole-Golgi le mecha ea phatlalatso Golgi. Ke sebopeho e khomaretse le ho lekareche lipakeng (arohaneng sebakeng). O emeloang ke ho bokella vesicles lera pakeng tsa reitkulumom le cis-Golgi.

The sethusathuto kaofela ke organelle haholo polymorphic (libopeho tse ngata). Esita le ka mekhahlelo e fapaneng ya ka seleng e 'ngoe e Golgi rarahaneng le ka ho shebahala fapaneng.

sethusathuto fapaneng le asymmetry. E teng haufi le tanka seleng ea khubung (cis-Golgi) e na le liprotheine tse ngata immature. Bakeng sa ho fana ka litanka tse khomaretse vesicles tswelela pele lera - vesicles. Ka ditanka fapaneng tse nang moahi enzyme tse fapa-fapaneng (catalytic), e fana ka maikutlo a hore ba tsoa le protheine maturing dithulaganyo feto-fetohe fapaneng.

Golgi rarahaneng. Mosebetsi.

Maikemisetso a sebopeho sa kenyeletsa lik'hemik'hale phetolo le lipalangoang tsa dintho kena ka ho sona. Liprotheine tse fatang maikutlo ka sethusathuto ho tswa reticulum endoplasmic ke substrate ka lekhetlo la pele ho potlakisang tsebetso ea lik'hemik'hale le. Tla mahloriso le phetolo enzyme ka vesicles isoa setša se khethiloe. Ka mohlala, sena se ka ba le ho sebaka sa sebopeho sa buds tse ncha. Ka ho kenya letsoho ha cytoplasmic thulaganyou e microtubules phetiso sebetsang haholo.

Golgi sethusathuto hape o etsa mosebetsi oa ho mabapi ea k'habohaedreite moieties ho liprotheine le ho sebelisa latelang liprotheine tsena ka kaho ea lera la le lysosomes ea lisele.

Ka itseng dimelametsing ka tswakana tsa sesebediswa sebōpeho sa likhoele cellulosic.

Golgi mesebetsi e rarahaneng tse fapa-fapaneng haholo. Har'a bona lokela ho totobatsa:

1. Hlopha, ntsha, bokella lihlahisoa secretory.
2. Bokella limolek'hule lipid, 'me sebopeho sa lipoproteins.
3. Phethoa protheine phetolo (posttranslational) kang glycosylation, sulphation le tse ling.
4. Sebopeho sa lysosomes.
5. Ho kopanela sebopeho sa acrosome ena.
6. The polysaccharide tswakana bakeng sa sebopeho sa waxes, glycoproteins, mucilages, marenene, popeho dintho ka mabota a ka cell ea dimela (pectins, hemicellulose, 'me batho ba bang).
7. Contractile vacuole sebopeho ka bonolo.
8. poleiti seleng ea sebopeho liseleng dimela ka mor'a karohano ea khubu ea.
