Thaum kawg ntawm lub zog stroke, myosin nyob rau hauv txoj haujlwm qis zog. … ATP ces khi rau myosin, txav cov myosin mus rau nws lub zog siab, tso lub taub hau myosin los ntawm qhov chaw ua haujlwm actin. ATP tuaj yeem txuas mus rau myosin, uas tso cai rau lub voj voog hla kev pib dua; ntxiv cov leeg nqaij tuaj yeem tshwm sim.
Puas yog ATP khi rau myosin?
Lub "hwj chim stroke" mechanism rau myosin txav raws actin filaments: … Kauj Ruam 3: ATP khi kuj ua rau muaj kev hloov pauv loj hauv 'sab caj npab' ntawm myosin uas khoov lub taub hau myosin mus rau hauv txoj hauj lwm txuas ntxiv ntawm cov filament.. ATP yog tom qab ntawd hydrolysed, tawm hauv inorganic phosphate thiab ADP khi rau myosin.
ATP khi qhov twg?
Lub ATP molecule khi rau qhov sib txuas ntawm txhua lub subunit ntawm lub dimer, qhia tias ATP nyob ze rau ob lub subunits thaum catalysis.
Dab tsi yog 3 lub luag haujlwm ntawm ATP hauv cov leeg nqaij?
Lub luag haujlwm tseem ceeb ntawm ATP hauv cov leeg nqaij: … ATP khi rau myosin taub hau thiab thaum hydrolysis rau ADP thiab Pi, hloov nws lub zog mus rau tus choj hla, ua kom muaj zog. 2. ATP yog lub luag haujlwm rau kev sib txuas ntawm tus choj myosin hla qhov kawg ntawm lub zog stroke.
Puas yog ATP xav tau rau actin-myosin khi ntawm kev tso tawm?
Tseem ceeb heev, peb xav tau ATP los pab kom tus choj actin-myosin hla mus rau kev tshem tawm, thiab tso lub zog los ntawm nws cov hydrolysis los pab kom lub taub hau myosinrov qab mus rau nws qhov chaw so.
