Ko te mahi o ribosomes me ētahi atu organelles pūtau

Whare herehere hei pūnaha wāhi

Live pūtau eukaryotic he ahurei pūnaha whakaritenga, pāhekoheko o wāhanga e whakarato ana mahi pūtau rite te kōwae wāhi. Ko te wāhanga matua ngā cytolemma tona cytoplasm me karihi, engari he maha ngā pūtau atu i organelles - hanganga motuhake rewa i roto i te cytoplasm me te whai wāhi i roto i te pākia o nga pūtau me te pūngao. Ko te kupu, nga mahi o ribosomes i te kōtuitanga pūmua, pungaraungao hua pūhui pūngao, microtubules tākaro he wāhi o te kōhiwi pūtau me te whakarato waka intracellular, me te kiriuwhi me te matatini Golgi - te matua "teihana" i roto i te pākia e. I roto i tenei take, tauhohenga katoa puta i roto i te cytoplasm, i te mea i roto i te nekehanga tamau.

organelles Membranous me ratou mahi

kawea Ko tōna mahi i roto i runga i te EPR ribosome, e kua kawea i roto i te kōputaputa o te membrane karihi i muri tonu te hanganga. EPR Ko te organelle membrane, arā, o te plurality o korere me nga whitiki, ki ia atu, me te kōrero ki te lumen o te membrane karihi. I roto i te pūtau, i reira e rua nga wahi o te kiriuwhi, rere i roto i rua hanganga me te mahi, maheni, me te taratara. Ko te tuatahi o ratou waha ana te ribosome, he hanganga me te mahi e kua whakatakotoria tonu i te putanga i te karihi, he mea motu tuarua nga ribosomes, a kua whai wāhi ai i roto i te ariā o lipids me steroids pūtau, toa konupūmā intracellular, dephosphorylates kūhuka-6-Phosphate i roto i te ate. Ko ngā momo e rua o EPR he hanganga impermanent me e ngohengohe ki huringa auau, me te te matatini Golgi. Ko reira rite i roto i te hanganga ki te EPR me ngā o te matatini o tāke, me tona mahi, ko te ki te whakaoti pūmua tuatahi synthesized i runga i te RER, te hanganga o lysosomes, te haaputuputuraa o ngā matū secretory me ratou waka i roto o te pūtau.

organelles kore-membrane

I roto i te pūtau, ki reira e ano organelles kore-membrane: cytoskeleton, centrioles taea matū whakakapinga (lipids, polysaccharides, matū kaha biologically uhi ranei) me te ribosome. Kua whakaritea nga mahi o ia o ratou i te tikanga whakamuri i te mea ti'aturi i runga i te āhua o tenei pākia: puta te whakaurunga i roto i te pūtau anake ka kōtuitanga te taikaha, e tuaruatia centrioles ka whakawhiti pūtau ki wehe, a kei te takahi microtubules ake ratou mahi i roto i te wāhanga o te whakatuwheratanga te awa waka me chemotaxis i roto i phagocytes . mahi Ribosome i roto i te pūtau tangata e ngā tamau, me te kore e rerekē rawa i te hunga i roto i te pūtau tipu. ngā ratou o ngā katote, ka whātatahia etahi RNA Biopolymer, kohia i roto i te rua subunits - 30raa me 50s (te whakarea o te te parataiao Svedberg) whakatu kupu, ribosome 80s. Ko te take tino nui i taea ai te tangata ki te wehewehe i te ribosome i te ribosomes o huakita he 70 hanganga, pera i roto i te maimoatanga o te mate kitakita e whakaritea paturopi taea o wāhanga tino ranei te ārai i te mahi o te 70 ribosomal tīpakongia, reira hëoi kōtuitanga pūmua i roto i tenei i te pūtau kitakita me te hëoi tona mahi.
