he aha ngā whekau e wehea ana i ia centrifugation

Te Whakapūngao: Te Whakakitenga i te Ao Huna o ngā Organelles

Kupu Whakataki:

He tikanga kaha te centrifugation e whakamahia ana i roto i ngā momo kaupapa pūtaiao, e taea ai te wehewehe i ngā wāhanga pūtau rerekē. I roto i te ao whakamīharo o te koiora pūtau, he mahi nui tā ngā organelles, ā, he mea nui kia mārama ki ā rātou mahi. Ka tūhuratia e tēnei tuhinga te tukanga whakamīharo o te centrifugation, ā, ka whakakitea ngā organelles ka taea te wehewehe pai mā te whakamahi i tēnei tikanga.

1. Te Mārama ki te Whakapūngao:

Ko te whakapūtanga he tukanga e whakamahi ana i te kaha o te whakaterenga whakapūtanga hei wehewehe i ngā wāhanga o te ranunga i runga i tō rātou mātotoru. Mā te huri tere i te ranunga i roto i te whakapūtanga, ka heke ngā matūriki taumaha ki raro, ka hanga he pirepire, ko ngā matūriki māmā ake ka noho tonu ki roto i te wai mata. Mā tēnei wehenga ka taea e ngā kaipūtaiao te wehe me te ako i ngā wāhanga takitahi e hiahiatia ana.

2. Te Mana o te Whakapūtanga Rerekētanga:

Ko te centrifugation rerekē he tikanga noa e whakamahia ana hei wehewehe i ngā okana i runga i ō rātou tere whakatō. Mā te whakamahi i tētahi raupapa o ngā takahuri tere-iti me ngā takahuri tere-nui, ka taea e tēnei tikanga te wehe i ngā okana rerekē i runga i te raupapa, i runga i ō rātou kiato. Mā tēnei ara, ka taea te wehewehe i tētahi ranunga matatini ki ngā wāhanga motuhake, ia wāhanga he okana motuhake kua whakareihia.

2.1 Ngā Pūnaha me ngā Mitochondria i te Hurihanga Tuatahi:

Ka whakamahia te centrifugation tuatahi i ngā tere iti iho hei wehewehe i ngā whekau nui ake pērā i ngā karihi me ngā mitochondria. He nui ake ngā kiato o ēnei whekau, ā, ka taea e rātou te whakatō i ngā tere puhoi ake. I muri i te takahuri tuatahi, ko te waikura kei roto ko te wāhanga cytoplasmic, ko te pellet kei roto ngā karihi me ngā mitochondria.

2.2 Te Reticulum Endoplasmic me te Taputapu Golgi i te Hurihanga Tuarua:

Ko te wai i puta mai i muri i te takahuri tuatahi, kei roto nei te wāhanga cytoplasmic, ka taea te huri tere ake hei whakapūpū i te reticulum endoplasmic (ER) me te taputapu Golgi. He matotoru waenga ō ēnei whekau, e kawenga ana mō te hanga pūmua, te whakarōpū, me te kawe. Nō reira, ka wehea rātou i tēnei taahiraa centrifugation tuarua.

3. Te Wehewehe i ngā Lysosomes me ngā Peroxisomes:

Ko ngā lysosomes me ngā peroxisomes, he mea nui mō te wawahi i ngā macromolecules me te tango i ngā matū kino, he whekau nui ēnei e rua e hiahia ana ki ngā tikanga motuhake mō te wehenga.

3.1 Te Whakapūtanga o te Rōrahi Kiato mō ngā Lysosomes:

Hei wehe i ngā lysosome, ka whakamahia te centrifugation pikinga mātotoru. Ko tēnei tikanga he waihanga i tētahi pikinga mātotoru e piki haere ana, ko te otinga tino mātotoru kei raro, ko te mea māmā kei runga. Ina centrifuged te ranunga kei roto ngā lysosome, ka neke ēnei whekau ki tō rātou rohe mātotoru motuhake i roto i te pikinga, ka taea ai te wehe i a rātou mai i ētahi atu wāhanga.

3.2 Te Whakapūngao-ā-Ultra mō ngā Peroxisome:

Nā te rite o te mātotoru i waenga i ngā peroxisome me ētahi atu okana, me whakamahi i ētahi atu tikanga hei wehe i a rātou. Ka taea te whakamahi i te ultracentrifugation, mā te whakamahi i ngā tere tino teitei, hei wehe i ngā peroxisome mai i te toenga o te ranunga. Mā te whakamahi i ngā rerekētanga iti o te mātotoru, ka taea te whiriwhiri i ngā peroxisome kia pai ai te ako me te tātari.

4. Ngā Tirohanga me ngā Whakamuatanga ā-Mārama:

I te whanaketanga o te hangarau, ka whakarei ake tonu ngā putanga hou o ngā tikanga centrifugation i tō tātou māramatanga ki ngā organelles me ā rātou mahi. Ko ngā whanaketanga hou o te whakamahi i te isopycnic density gradient centrifugation me te whakamahinga o te nanotechnology kua tino whai wāhi ki te tika me te whai huatanga o te wehenga organelle, ā, ka waiho hei taputapu kaha mō te rangahau koiora pūtau.

Whakatau:

He mea nui te mahi a te centrifugation ki te mārama ki te hanganga uaua o te pūtau mā te tuku i te wehenga o ngā whekau. Mai i ngā karihi ki ngā mitochondria, te reticulum endoplasmic ki te taputapu golgi, ngā lysosomes ki ngā peroxisome, he mahi me ngā tikanga motuhake kei ia o ēnei whekau. Mā ngā tikanga centrifugation, me ngā huarahi auaha, ka taea e ngā kaipūtaiao te ruku hohonu ki te ao uaua o ngā pūtau, me te wetewete i ngā mea ngaro e huna ana i roto i ō rātou whekau.
