Ngā Tauira Pātai e Matapaki ana i te Mahi a ngā Whākōkī
He pūmua matatini ngā whākōkī e mahi ana hei whakakorikori i roto i ngā tauhohenga matū koiora e puta ana i roto i ngā rauropi ora. Ka whakateretere i te tere o ngā tauhohenga me te kore e pau i roto i te tukanga. He mea nui te mārama ki te mahi a ngā whākōkī, inā koa mō ngā ākonga e ako ana i te koiora me te matū. I roto i tēnei tuhinga, ka tūhuratia e mātou ētahi tauira raruraru, ka matapakihia hoki te mahi a ngā whākōkī kia mārama ake ai tēnei kaupapa nui.
He Kupu Whakataki ki ngā Whākōkī me ā rātou Mahi
He mahi nui tā ngā whākōkī i roto i te nuinga o ngā tukanga ā-tinana o te tinana. Ka whai wāhi atu rātou ki te nakunaku kai, te hanga ira DNA, te hurihanga pūngao matū, tae atu ki te tango paitini. He tino motuhake ia whākōkī ki tētahi matū motuhake, e mahi ana i runga i te tauira raka-me-kī, i te tauira whakauru rānei.
1. Tauira Raka me te Kī: He āhua motuhake ō ngā whākōkī me ngā matūriki, me hono tahi pērā i te raka me te kī kia puta ai he tauhohenga.
2. Tauira Urutau Whakaoho: Ka taea e ngā whākōkī te whakarerekē i ō rātou āhua ina whakatata te papa ki te ōrite ki te hanganga o te papa, ka taea ai te haere tonu o te tauhohenga me te whai hua ake.
Ngā Pātai Tauira me te Kōrero
Anei ētahi tauira pātai me ngā kōrero mō te mahi a ngā whākōkī:
Pātai 1:
Ka mātakitaki tētahi kairangahau i te mahi a tētahi whākōkī me tētahi matū motuhake i ngā pāmahana rerekē. I ngā pāmahana teitei, he tino iti te mahi a te whākōkī. He aha tēnei e tupu ana?
Kōrero:
He tino tairongo ngā whākōkī ki ngā huringa pāmahana. He pāmahana tino pai tō ia whākōkī e tino teitei ai tana mahi. Ka taea e ngā pāmahana tino tiketike te whakapōrearea, he huringa i roto i te hanganga toru-ahu o te whākōkī. Ko te hanganga pūmua o te whākōkī kua whakapōrearea ka ngaro tana mahi nā te mea ka huri te āhua o tōna pae hohe, ka kore e taea te here pai ki te papa. Nō reira, i ngā pāmahana teitei, ka heke te mahi a te whākōkī nā te whakapōrearea.
Pātai 2:
Ka pēhea te mahi a te whākōkī mēnā ka tino rerekē te pH o te taiao mai i te pH tino pai o te whākōkī?
Kōrero:
Pērā i te pāmahana, he pH tino pai anō hoki tō ngā whākōkī. Ka pāngia pea te whakakōkī o ngā waikawa amino i roto i te pae hohe o te whākōkī e ngā panoni nui o te pH, ā, ka whakararuraru i ngā hononga ionic i roto i te hanganga o te whākōkī. Ina tawhiti te pH i waho o te awhe tino pai, ka ngaro te hononga o te whākōkī ki te papa, ka whakarerekē rānei i tōna āhua. Nō reira, ka heke, ka mutu rānei te mahi a te whākōkī.
Pātai 3:
Whakamāramahia te mātāpono mahi a ngā aukati whākōkī whakataetae, me te homai i ngā tauira o te pānga o tēnei ki te haerenga o ngā tauhohenga whākōkī.
Kōrero:
Ko te aukati whakataetae he ngota e whakataetae ana ki te matūriki hei here ki te pae hohe o te whākōkī. Mā tēnei ka ārai i te matūriki kia kaua e uru ki te pae hohe, ā, ka ārai hoki i te puta o te tauhohenga. Hei tauira, mēnā he rite te hanganga o te matūriki ki te aukati, ka taea e te aukati te noho i te pae hohe, ka ārai i te matūriki kia kaua e uru. Nō reira, ka heke te tere o te tauhohenga whākōkī.
Hei tauira, i roto i te huringa pākia o te waikawa folic i roto i ngā huakita, ka mahi ngā rongoā sulfonamide hei aukati whakataetae, e whakataetae ana ki te waikawa para-aminobenzoic (PABA) matūriki. Ka mutu te hanga waikawa folic, ā, ka mutu te tipu o ngā huakita.
Pātai 4:
He pēhea te pānga o ngā aukati allosteric ki te mahi a ngā whākōkī?
Kōrero:
Kāore ngā aukati allosteric e herea ki te pae hohe, engari ki ētahi atu pae e mōhiotia ana ko ngā pae allosteric. Ina herea ēnei aukati ki ngā pae allosteric, ka puta he huringa āhua i roto i te whākōkī, tae atu ki tōna pae hohe. Ka taea e tēnei te whakaiti i te hononga o te whākōkī ki te matū, te huri rānei i te whākōkī ki tētahi āhua kore mahi. Ko te aukati allosteric tētahi o ngā huarahi matua hei whakahaere i te mahi whākōkī, he mea nui i roto i ngā ara pākia uaua. Ko tētahi tauira matarohia o te aukati allosteric ko te aukati urupare i roto i te huringa Krebs, i reira ka aukati te hua whakamutunga o tētahi tauhohenga i te whākōkī tīmatanga hei ārai i te nui rawa o te whakaputanga.
Te Whakawhanaketanga Anō
He mea nui te mārama ki te mahi a ngā whākōkī, ehara i te mea i roto i te pūtaiao taketake anake, engari i roto hoki i ngā mahi haumanu me ngā mahi ahumahi. He maha ngā wā ka whakamahia e te umanga hangarau koiora ngā whākōkī i roto i te hanga i ngā momo hua, mai i te kai ki ngā rongoā.
Ko tētahi mea me mōhio ngā ākonga ko te hiranga o ngā mahi taiwhanga. Mā ngā whakamātautau ā-ringa e tirotiro ana i ngā pānga o te pāmahana, te pH, me te kukū o te matū ki te mahi whākōkī ka whakarei ake i te māramatanga ki tēnei ariā. Hei tāpiri, mā ngā whakamātautau e whakamahi ana i ngā aukati, whakataetae me ngā kore-whakataetae, ka whakaratohia he māramatanga atu ki te whakahaere whākōkī i roto i ngā horopaki o te ao tūturu.
Whakamutunga
Kua matapakihia e tēnei tuhinga ētahi tauira raruraru, ā, kua whakaratohia he kōrero mō te mahi a ngā whākōkī. Ko te hiranga o ngā whākōkī i roto i ngā tukanga koiora me ō rātou whakamahinga i te oranga o ia rā e whakaatu ana i te hiahia kia mārama pai ki tēnei kaupapa mō te hunga e hiahia ana ki te pūtaiao, inā koa te koiora me te matū. Mā te ako me te mahi tonu, ka taea e tātou te mārama ake ki te uaua me te ataahua o ngā pūnaha koiora e whakahaerehia ana e ngā whākōkī.
