Thaum lub paj hlwb tsis ua rau muaj kev cuam tshuam, piv txwv li so, lub axoplasm hauv axon muaj siab concentration ntawm K + thiab tsis zoo them cov proteins thiab qis concentration ntawm Na +. Nyob rau hauv so, lub axonal membrane yog sib piv ntau permeable rau K + ions thiab ze li impermeable rau Na + ions.
Tus nqi hauv axoplasm yog dab tsi thaum lub sijhawm so?
Cov ionic gradients thoob plaws cov ntaub so ntswg yog khaws cia los ntawm kev thauj mus los ntawm ions los ntawm sodium-potassium twj uas thauj 3 Na+ tawm mus rau 2 K + rau hauv lub cell thiab li no sab nrauv ntawm lub axonal membrane muaj tus nqi zoo thaum nws sab hauv ua tsis zoo thiab …
Dab tsi yog qhov suav nrog hauv axoplasm ntawm so axon?
2. Yog li ntawd, axoplasm nyob rau hauv lub axon muaj ib tug siab concentration ntawm K + thiab tsis zoo nqi proteins thiab ib tug tsawg concentration ntawm Na +.
Axoplasm tam sim no yog dab tsi?
Axoplasm yog tsim los ntawm ntau yam organelles thiab cytoskeletal ntsiab. Lub axoplasm muaj cov ntsiab lus siab ntawm elongated mitochondria, microfilaments, thiab microtubules. Axoplasm tsis muaj ntau ntawm cov tshuab ntawm tes (ribosomes thiab nucleus) yuav tsum tau sau thiab txhais cov proteins nyuaj.
Axoplasm yog dab tsi?
