Lawv txuas mus rau sarcolemma ntawm lawv qhov kawg , yog li cov myofibrils myofibrils Myofilaments yog ob qho protein filaments ntawm myofibrils hauv cov leeg nqaij. Ob lub proteins yog myosin thiab actinthiab yog cov proteins uas cuam tshuam rau cov leeg nqaij. Ob lub filaments yog ib qho tuab uas muaj feem ntau ntawm myosin, thiab ib qho nyias uas muaj feem ntau ntawm actin. https://en.wikipedia.org › wiki › Myofilament
Myofilament - Wikipedia
luv, tag nrho cov leeg nqaij daim ntawv cog lus (Daim duab 19.34). … Cov tsos mob ntawm cov nqaij pob txha pob txha yog tshwm sim los ntawm kev rov ua dua ntawm cov proteins actin thiab myosin uas muaj nyob ntawm qhov ntev ntawm myofibrils.
myosin taub hau khi rau dab tsi?
Lub taub hau ntawm myosin khi actin, tsim cov choj hla ntawm myosin thiab actin filaments. Qhov (ntxiv …) Ntxiv rau kev khi actin, myosin taub hau khi thiab hydrolyze ATP, uas muab lub zog rau tsav filament zawv zawg.
myosin taub hau khi nyob qhov twg?
Thaum cov leeg sib cog lus, lub taub hau ntawm lub taub hau ntawm cov tuab myosin filaments txuas mus rau qhov chaw sib khi ntawm cov tawv nqaij nyias nyiasthiab rub lawv mus rau ib leeg. Txij li cov fibers nyias yog khi rau hauv kab Z, zawv zawg ntawm cov filaments ua rau txhua tus sarcomere - thiab yog li cov nqaij fibers - kom luv.
myosin txuas rau dab tsi?
Myosin khi rau actin ntawm qhov chaw sib khi ntawm globular actin protein. Myosin muaj lwm qhov chaw sib txuas rau ATP ntawm qhov kev ua haujlwm enzymatic hydrolyzes ATP rau ADP, tso tawm ib qho inorganic phosphate molecule thiab lub zog. ATP khi ua rau myosin tso tawm actin, tso cai rau actin thiab myosin cais tawm ntawm ib leeg.
Dab tsi txuas rau sarcolemma?
Ntawm nruab nrab ntawm lub sarcomere yog kab M, qhov twg cov tuab filaments yog interconnected los ntawm M protein thiab myosin. … Ob qhov loj structural complexes koom nyob rau hauv kev sib txuas ntawm sarcomeric proteins thiab extracellular matrix muaj xws li the membrane-spanning integrin complex thiab dystrophin complex
