Cov cytoskeleton cov tsos mob Ntawm lub cell yog tsim los ntawm microtubules, actin filaments, thiab intermediate filaments. Cov qauv no muab lub xovtooj ntawm nws cov duab thiab pab npaj cov khoom ntawm tes. Tsis tas li ntawd, lawv muab lub hauv paus rau kev txav mus los thiab kev faib tawm ntawm tes.

Raws li txoj cai, 3 cytoskeletal ntsiab yog dab tsi?

Peb lub ntsiab structural Cheebtsam ntawm lub cytoskeleton yog microtubules (tsim los ntawm tubulins), microfilaments (tsim los ntawm actins) thiab nruab nrab filaments. Tag nrho peb lub ntsiab lus cuam tshuam nrog ib leeg uas tsis yog-covalently.

Ib tug kuj yuav nug, dab tsi yog peb lub ntsiab cytoskeletal proteins thiab lawv lub luag haujlwm? Ces tshawb lub peb lub ntsiab hom ntawm cov proteins uas ua rau cytoskeleton cov tsos mob : microfilaments, intermediate filaments, thiab microtubules, thiab cov muaj nuj nqi ntawm txhua tus.

Tsis tas li ntawd, cytoskeleton yog dab tsi thiab nws txoj haujlwm yog dab tsi?

Los ntawm ib tug series ntawm intercellular cov proteins , lub cytoskeleton muab ib cell nws puab , muaj kev txhawb nqa, thiab txhawb nqa kev txav mus los los ntawm peb lub ntsiab Cheebtsam: microfilaments, intermediate filaments, thiab microtubules.

Dab tsi yog peb hom fibers loj uas ua rau lub cytoskeleton thiab lawv lub luag haujlwm yog dab tsi?

Peb hom loj ntawm filaments ua kom lub cytoskeleton : actin filaments, microtubules, thiab intermediate filaments. Actin filaments tshwm sim hauv a cell nyob rau hauv daim ntawv ntawm meshworks los yog bundles ntawm parallel fibers ; lawv pab txiav txim seb cov duab ntawm lub cell thiab kuj pab nws ua raws li lub substrate.
