Golgi hadaddun: sifa da aiki na wasu gabbansa

Golgi na'ura - wani muhimmin organelle da cewa shi ne yanzu a kusan kowane eukaryotic cell. Zai yiwu ne kawai Kwayoyin cewa rasa wannan hadadden ne ja da maikacin jini na vertabrate. Wannan tsarin ayyuka ne sosai bambancin. Yana da yake a cikin abin hawa tank da kuma tara tare duk mahadi samar da tantanin halitta, sa'an nan kuma sha kara kasawa, gyara, redistribution da kuma sufuri.

Duk da cewa da Golgi na'ura da aka samu a 1897, da kuma wasu da ayyuka na rayayye yi karatu a kwanan. Ka yi la'akari da mafi cikakken fasali na da tsarin da kuma aiki.

Golgi na'ura: tsarin

Wannan organelle membrane ne mai sa na tankuna da suke da hankali dab da juna, kama wani tari. Tsarin da kuma aikin naúrar aka dauke dictyosome.

Dictyosome ne mai raba, m ɓangare na Golgi inji, wanda ya kunshi 3 - 8 ne a hankali dab da juna tankuna. A tari na wadannan membrane tank aka kewaye da wani tsarin na kananan vacuoles da vesicles - a cikin wannan hanya ne da za'ayi da kai daga abubuwa, kazalika da sadarwa dictyosomes tsakanin kansu da kuma sauran salula Tsarin. Yawanci, da dabba Kwayoyin suna da daya kawai dictyosomes, yayin da a shuka Tsarin, akwai iya zama da yawa.

A dictyosome a raba biyu na ƙyallen maƙalawa - da CIS kuma trans gefe. Kish-gefen ta wajen core kuma granular endoplasmic cibiyar sadarwa. A nan a cikin nau'i na membrane vesicles hawa hada sunadaran da sauran mahadi. A wannan karshen dictyosomes kullum sabon tankuna ake samar.

Trans-gefe suna fuskantar jikin tantanin. Yawancin lokaci, yana da wani bit fadi. Ga zo dangane da ya wuce duk matakai na gyara. Daga kasa na tanki ne kullum tsage kananan vacuoles da vesicles, wanda transports da abu da ake so kwayoyin halitta.

Golgi na'ura: aiki

Kamar yadda aka ambata a riga, da wasu gabbansa ayyuka ne sosai bambancin.

• Ga gyara aka yi sabuwar hada sunadarai na gina jiki. A mafi yawan lokuta, da sunadarin ne a haɗe zuwa wani carbohydrate, sulphate ko wani phosphorus m. Saboda haka, Golgi na'ura alhakin samuwar sunadaran da jini membrane, enzymes da kuma lysosomal sunadaran.
• Golgi inji shi ne alhakin kai na modified sunadarai a wasu cell shafukan. Daga trans-hannu har abada rabu kananan kumfa, wanda ya ƙunshi cikakken sunadaran.
• A nan, da samuwar da sufuri da na lysosomal enzymes.
• A cavities na tanki akwai wani jari na lipids, da kuma ƙarshe da samuwar lipoproteins - hadaddun na gina jiki da kuma sia kwayoyin.
• Golgi na'ura na da wata shuka cell alhakin kira na polysaccharides, wanda ake bi ta hanyar samuwar tantanin halitta bango na shuke-shuke, kazalika da gamsai, pectins, hemicellulose da waxes.
• Bayan rarraba shuka Kwayoyin Golgi hadaddun daukan bangare a cikin samuwar tantanin halitta farantin.
• A wannan maniyyi organelle daukan bangare a cikin samuwar na acrosome enzymes, da wanda yake shi ne halakar da kwai membranes a hadi.
• A Kwayoyin wakilan protozoa na Golgi hadaddun ne alhakin da samuwar contractile vacuoles cewa gwada osmotic matsa lamba.

Hakika, wannan ba wani cikakken jerin duk da ayyuka. Modern masana kimiyya har yanzu gudanar da wani iri-iri na gudanar da bincike, ta amfani da fasahar ta zamani. Shi ne wata ila cewa a cikin gaba 'yan shekaru, a jerin da Golgi hadaddun ayyuka za su karu sosai. Amma za mu iya riga ce yaƙĩni da cewa wannan organelle goyon bayan da al'ada aiki daga cikin sel kuma dukan kwayoyin.
