Ngā whākōkī: Ngā Whakakorikori Koiora e Ārahi Ana i te Ora
He ngota 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. Hei whakakorikori, ka tere ake ngā tere tauhohenga e ngā whākōkī me te kore e pau i roto i te tukanga, ka taea ai e ngā rauropi te whakahaere i ngā tauhohenga e tika ana kia ora ai. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā āhuatanga, ngā mahi, me te hiranga o ngā whākōkī i roto i ngā āhuatanga rerekē o te ora koiora, tae atu ki ā rātou tono i roto i te ahumahi me te rangahau.
Hanganga me ngā Āhuatanga o ngā Whākōkī
Ko ngā whākōkī he pūmua i hangaia mai i ngā mekameka roa o ngā waikawa amino kua whakapikohia ki roto i tētahi hanganga toru-ahu motuhake. Mā tēnei hanganga ka taea e ngā whākōkī te whai i tētahi pae hohe, he rohe motuhake e taunekeneke ana ki te papa - te ngota ka hurihia e te whākōkī. Kei tēnei pae hohe te āhua me ngā āhuatanga matū e tika ana hei here i te papa, he rite tonu ki te wēneti e uru ana ki tētahi pūtu motuhake.
Ko ngā āhuatanga nui o ngā whākōkī ko te tino motuhake mō ētahi matū, te tino whai huatanga ki te whakapiki i ngā tere tauhohenga, me te kaha ki te mahi i raro i ngā āhuatanga taiao noa, pērā i te pāmahana tinana me te pH kūpapa. Nā ēnei āhuatanga ahurei ka tino ātaahua ngā whākōkī mō te rangahau me ngā tono mahi.
Te Mahi me te Tikanga o te Mahi a te Whākōkī
Ko te mahi matua a ngā whākōkī i roto i ngā pūtau he whakaiti i te pūngao whakahohe o ngā tauhohenga matū, te pūngao iti rawa e hiahiatia ana kia puta ai tētahi tauhohenga. Mā te whakaiti i te pūngao whakahohe, ka taea e ngā whākōkī te tere ake te puta o ngā tauhohenga me te iti ake o te pūngao i tō te korenga. Ka mahi ngā whākōkī mā roto i tētahi tikanga e mōhiotia ana ko te "tauira maukati-me-te-kī" te "whakaurunga induced" rānei, e whakaahua ana i te taunekeneke a ngā whākōkī me ngā matū.
I roto i te tauira raka-me-te-kī, he āhua motuhake tō te pae hohe o te whākōkī e uru ana ki tētahi matū motuhake anake, pērā i te kī e uru ana ki tētahi raka motuhake anake. I roto i te tauira taunga whakaoho, ina herea he matū ki te pae hohe, ka paku rerekē te hanganga o te whākōkī kia pai ake ai te uru ki te matū. Ka taea e tēnei huringa hanganga te āwhina i te whakanoho i te matū kia māmā ake ai te tauhohenga.
Te Tūranga o ngā Whākōkī i roto i te Pūnaha Whakapūngao
Ko te pākia o te tinana te raupapa o ngā tauhohenga matū i roto i tētahi rauropi e tika ana hei pupuri i te ora. He mahi nui tā ngā whākōkī i roto i te pākia o te tinana, i roto i ngā tauhohenga anabolic, e hanga ana i ngā ngota nui, matatini mai i ngā mea iti, me ngā tauhohenga catabolic, e wawahi ana i ngā ngota nui ki ngā mea iti ake hei whakaputa pūngao.
Hei tauira, ko te whākōkī amylase i roto i te huware ka āwhina i te wawahi i ngā warowaihā ki ngā huka māmā, ka tīmata ai te tukanga nakunaku. I roto i ngā pūtau, ka āwhina ngā whākōkī pēnei i te hexokinase i te taahiraa tuatahi o te ara glycolysis, te wāhi e hurihia ai te hukahuka ki te hukahuka-6-phosphate, he taahiraa nui i roto i te whakaputa pūngao pūtau.
Te Whakahaere i te Mahi a te Whākōkī
Kāore te mahi a te whākōkī i roto i ngā pūtau e pumau, ā, ka taea te whakahaere mā roto i ētahi tikanga hei whakarite kia tutuki i te pākia o te pūtau ngā hiahia o te pūtau. Ka taea tēnei whakahaere mā roto i ngā aukati whākōkī, arā, ngā ngota e whakaiti ana, e aukati ana rānei i te mahi a te whākōkī. Ka taea e ngā aukati te whakataetae, te whakataetae ki te papa mō te here ki te pae hohe, te kore whakataetae rānei, te here ki ētahi atu wāhanga o te whākōkī hei whakarerekē i tōna āhua, i tōna mahi rānei.
Hei tāpiritanga, ka taea hoki te whakahohe, te whakakore rānei i ngā whākōkī mā roto i ngā huringa matū pērā i te phosphorylation, te de-phosphorylation rānei, tae atu ki te whakahaere allosteric, te wāhi e herea ai ngā ngota whakahaere ki ngā pae ehara i te pae hohe hei whakarerekē i te mahi whākōkī.
Ngā whākōkī i roto i ngā tono ahumahi
Ehara i te mea he mea nui ngā whākōkī i roto i ngā horopaki koiora anake, engari he maha hoki ngā whakamahinga i roto i ngā ahumahi me ngā hangarau. I roto i te ahumahi kai, ka whakamahia ngā whākōkī hei whakatere i te whakapūkara, hei tukatuka i te tiihi, hei whakapai ake i te kakano me te kounga o ngā hua tunu taro. Hei tauira, ka whakamahia ngā whākōkī protease hei whakangawari i te mīti me te whakaputa i ngā hydrolysates pūmua.
I roto i te hangarau koiora, he mahi nui tā ngā whākōkī i roto i ngā tikanga DNA recombinant, e whakamahia ai ngā whākōkī here hei tapahi i te DNA i ngā wāhi motuhake, me ngā ligase hei hono i ngā wahi DNA. E whakamahia ana hoki ngā whākōkī i roto i te hanga wahie koiora, e wawahi ai ngā whākōkī pēnei i te cellulase i te cellulose mai i ngā rauemi tipu hei huka ka taea te whakapūkara hei etanoru.
Rangahau me te Anamata o ngā Whākōkī
He mea whakamīharo tonu ngā whākōkī i roto i ngā rangahau pūtaiao nā te mea he maha ngā momo whakamahinga ka taea te whakamahi. Nā te whanaketanga o ngā whākōkī hangarau mā roto i ngā tikanga pēnei i te whanaketanga whaimana kua whakawātea i te huarahi mō te whakaputa whākōkī me ngā āhuatanga pai ake me te pumau mō ngā whakamahinga motuhake.
Hei tāpiri atu ki tēnā, kei te hohonu haere te rangahau mō ngā whākōkī i roto i te horopaki o te hauora tangata. Hei tauira, mā te mārama ki ngā whākōkī e pā ana ki ngā mate pākia, ki te mate pukupuku rānei, ka huaki ngā whai wāhitanga mō te whakawhanake i ngā maimoatanga e hangai ana ki ngā whākōkī ka taea te arotahi ki ngā ara matū koiora motuhake o te tinana.
Whakamutunga
He wāhanga nui ngā whākōkī o te ora, e whakahaere ana i te nuinga o ngā tauhohenga matū koiora i roto i ngā rauropi. Mā tā rātou mahi hei whakakorikori koiora ka taea e rātou te whakatere i ngā tauhohenga me te tino whai hua me te motuhake. Mā te māramatanga hohonu ki ngā whākōkī, ehara i te mea ka homai he māramatanga ki ngā tikanga taketake o te ora engari ka whakatuwherahia hoki he tono ahumahi me te hauora tino nui. I te heke mai, ka oati te rangahau whākōkī i ngā kitenga hou ka taea te whakarerekē i te huarahi e whakamahia ai e tātou te matū koiora hei whakapai ake i te kounga o te oranga tangata.
