yiziphi i-organelles ezihlukaniswayo ku-centrifugation ngayinye

I-Centrifugation: Ukwembula Umbuso Ofihliwe We-Organelles

Isingeniso:

I-Centrifugation iyindlela enamandla esetshenziswa emikhakheni eyahlukene yesayensi, evumela ukuhlukaniswa kwezingxenye ezahlukene zamaseli. Ezweni elithakazelisayo le-biology yamaseli, ama-organelle adlala indima ebalulekile futhi ukuqonda imisebenzi yawo kubalulekile. Lesi sihloko sihlola inqubo ethakazelisayo ye-centrifugation futhi sembula ama-organelle angahlukaniswa ngempumelelo kusetshenziswa le ndlela.

1. Ukuqonda i-Centrifugation:

I-Centrifugation inqubo esebenzisa amandla okusheshisa kwe-centrifugal ukuhlukanisa izingxenye zengxube ngokusekelwe ekubuneni kwazo. Ngokufaka ingxube ekujikelezeni okusheshayo ngaphakathi kwe-centrifuge, izinhlayiya ezisindayo ziyahamba ziye phansi, zakha i-pellet, kuyilapho izinhlayiya ezikhanyayo zihlala ku-supernatant. Lokhu kuhlukaniswa kwenza ososayensi bakwazi ukuhlukanisa nokutadisha izingxenye ngazinye ezizithandayo.

2. Amandla Okuhlukanisa I-Centrifugation:

I-differential centrifugation iyindlela evamile esetshenziselwa ukuhlukanisa ama-organelle ngokusekelwe kumazinga awo okuthuthwa kwenhlabathi. Ngokusebenzisa uchungechunge lwe-low speed kanye ne-high-speed spins, le ndlela ivumela ukuhlukaniswa kwama-organelle ahlukahlukene ngokulandelana, ngokusekelwe ekuminyaneni kwawo. Ngale ndlela, ingxube eyinkimbinkimbi ingahlukaniswa ibe yizingxenye ezihlukile, ngayinye icebile ngama-organelle athile.

2.1 I-Nuclei ne-Mitochondria ku-First Spin:

Ukuqala ngesivinini esiphansi kusetshenziselwa ukuhlukanisa ama-organelle amakhulu njenge-nuclei ne-mitochondria. Lawa ma-organelle anobuningi obuphezulu futhi ayakwazi ukudilika ngesivinini esiphansi. Ngemva kokujikeleza kokuqala, i-supernatant yakhiwa ingxenye ye-cytoplasmic, kuyilapho i-pellet iqukethe ama-nuclei ne-mitochondria.

2.2 I-Endoplasmic Reticulum kanye ne-Golgi Apparatus ku-Second Spin:

I-supernatant etholakala ngemuva kokujikeleza kokuqala, equkethe ingxenye ye-cytoplasmic, ingadlula ekujikelezeni okusheshayo ukuze ifake i-endoplasmic reticulum (ER) kanye ne-Golgi apparatus. Lawa ma-organelle, abhekene nokuhlanganiswa kwamaprotheni, ukuhlunga, kanye nokuthutha, anobuningi obuphakathi. Ngakho-ke, ahlukaniswe kulesi sinyathelo sesibili se-centrifugation.

3. Ukuhlukanisa ama-Lysosome nama-Peroxisome:

Ama-lysosome nama-peroxisome, abalulekile ekubhujisweni kwama-macromolecule kanye nokukhishwa kwe-detox ezintweni eziyingozi, ngokulandelana, angama-organelle amabili abalulekile adinga amasu athile okuhlukanisa.

3.1 I-Centrifugation ye-Density Gradient yama-Lysosomes:

Ukuze kuhlukaniswe ama-lysosome, kuvame ukusetshenziswa i-centrifugation ye-density gradient centrifugation. Le ndlela ihilela ukudala i-gradient yokwanda kobuningi, lapho isixazululo esiqinile kakhulu siphansi kanti esilula kakhulu siphezulu. Lapho ingxube equkethe ama-lysosome ifakwa i-centrifuge, lawa ma-organelle aya esifundeni sawo esithile sobuningi ngaphakathi kwe-gradient, okuvumela ukuhlukaniswa kwawo nezinye izingxenye.

3.2 I-Ultracentrifugation yama-Peroxisomes:

Ngenxa yokufana kobuningi phakathi kwama-peroxisome namanye ama-organelle, kudingeka ezinye izindlela zokuwahlukanisa. I-Ultracentrifugation, kusetshenziswa isivinini esikhulu kakhulu, ingasetshenziswa ukuhlukanisa ama-peroxisomes kulo lonke ingxube. Ngokusebenzisa umehluko omncane wobuningi, ama-peroxisome angaxutshwa ngokukhetha, okwenza kube lula ukutadisha nokuhlaziya kwawo.

4. Imibono Nentuthuko Yesikhathi Esizayo:

Njengoba ubuchwepheshe buthuthuka, intuthuko entsha kumasu okuhlanganisa i-centrifugation iqhubeka nokuthuthukisa ukuqonda kwethu ama-organelle nemisebenzi yawo. Intuthuko yakamuva esebenzisa i-isopycnic density gradient centrifugation kanye nokusetshenziswa kwe-nanotechnology kube negalelo elikhulu ekuqondeni nasekusebenzeni kahle kokuhlukaniswa kwama-organelle, okwenza kube amathuluzi anamandla ocwaningo lwebhayoloji yamaseli.

Isiphetho:

I-Centrifugation idlala indima ebalulekile ekuqondeni ukwakheka kwamaseli okuyinkimbinkimbi ngokuvumela ukuhlukaniswa kwama-organelle. Kusukela kuma-nuclei kuya kuma-mitochondria, i-endoplasmic reticulum kuya ku-golgi apparatus, ama-lysosome kuya kuma-peroxisomes, ngalinye lala ma-organelle linemisebenzi nezindlela ezihlukile. Amasu e-Centrifugation, ahlanganiswe nezindlela ezintsha, enza ososayensi bakwazi ukujula ezweni eliyinkimbinkimbi lamaseli, bevula izimfihlo ezifihliwe ngaphakathi kwama-organelles abo.
