Golgi hadaddun

Golgi hadaddun aka gano ta Kamillo Goldzhi a 1898. Wannan tsari ne ba a cikin cytoplasm kusan duk eukaryotic (mafi girma kwayoyin aka gyara) na sel, musamman secretory Kwayoyin a dabbobi.

Golgi hadaddun. Tsarin.

Tsarin shi ne wani tari na mĩƙe bags membranes. Su kira ramukan. Wannan tari na bags ake dangantawa da wani tsarin na vesicles (kumfa Golgi). ci gaba da faruwa a cikin samuwar sabuwar tankuna Fusion vesicles cewa toho daga endoplasmic reticulum (cavities cibiyar sadarwa) daga daya karshen stacks na bags. Daga wani cikakken maturation da kumfa ta soke sake a cikin wannan ƙarshen tari ga voyayyen bangarorin na tanki. Kamar wancan akwai karɓa mai motsi da tankuna a tuddai zuwa ciki gefen daga cikin matsanancin gefen.

A tank tsarin auku maturation sunadaran ƙaddara ga mugunya transmembrane sunadarai na jini membrane sunadarai na lysosomes da sauransu. Ripening jamiái motsa sequentially Tank wasu gabbansa. A cikinsu akwai wani karshe nadawa sunadarai ba da su gyare-gyare - phosphorylation da glycosylation.

Shuka Kwayoyin suna halin da yawan mutum dictyosomes (stacks). A dabba Kwayoyin sau da yawa da mahara stacks alaka ko shambura babban tari.

Inji (hadaddun) Golgi ƙunshi hudu babban sassan: da trans-Golgi cibiyar sadarwa, da Kish-Golgi na'ura, da trans-Golgi da Golgi kafofin watsa labarai. By tsarin ne a haɗe kuma zuwa wani tsaka-tsaki daki (raba yankin). Ya aka wakilta jari na membrane vesicles tsakanin reitkulumom da Kish-Golgi.

Dukan inji shi ne wani organelle sosai polymorphic (a sassan ayyukan). Ko a matakai daban-daban na sel guda na Golgi hadaddun iya samun daban-daban look.

Daban-daban na'ura da kuma jeri na bangaren. An located kusa da cell nucleus din tank (CIS-Golgi) dauke da mafi m sunadarai. Domin tankuna da cewa ana ci gaba a haɗe membrane vesicles - vesicles. A daban-daban tankuna dauke da daban-daban mazaunin enzymes (catalytic), wanda ya nuna cewa su zo daga maturing gina jiki consistently daban-daban tafiyar matakai.

Golgi hadaddun. Aiki.

A manufofin da tsarin hada sinadaran da gyara da kuma sufuri na abubuwa shiga da shi. Sunadaran iya shiga cikin na'ura daga endoplasmic reticulum ne na farko substrate ga enzyme. Akuma taro kuma gyara enzymes a vesicles hawa zuwa wani kaddamarda shafin. Alal misali, wannan yana iya zama wani yanki na samuwar sabuwar buds. Tare da sa hannu na cytoplasmic microtubules canja wurin tsari ne mafi aiki.

Golgi na'ura kuma yi aikin aiki na dangane da carbohydrate moieties zuwa sunadaran da m amfani da wadannan sunadarai a gina membranes da lysosomes na sel.

A wasu algae a cikin kira na da na'urar tsarin cellulosic zaruruwa.

Golgi hadaddun ayyuka ne quite bambance bambancen. Daga cikin su ya kamata a alama:

1. Rarrabẽwa, kawar da nakiyar, jari na secretory kayayyakin.
2. Jari na sia kwayoyin da kuma samuwar lipoproteins.
3. Gamawa furotin gyara (posttranslational) kamar glycosylation, sulphation da sauran.
4. Da samuwar lysosomes.
5. Saka hannu cikin samuwar na acrosome.
6. A polysaccharide kira ga samuwar waxes, glycoproteins, mucilages, gumis, matrix abubuwa a cikin cell ganuwar shuke-shuke (pectins, hemicellulose, da sauransu).
7. Contractile vacuole samuwar a cikin sauki.
8. cell farantin samuwar a shuka Kwayoyin bayan rabo daga cikin tsakiya.
