Vim li cas peb xav tau calcium rau cov leeg nqaij?
Calcium pab tswj cov leeg nqaij. Thaum cov hlab ntsha txhawb cov leeg, lub cev tso calcium. Cov calcium pab cov proteins hauv cov leeg ua haujlwm ntawm kev cog lus. Thaum lub cev tso cov calcium tawm ntawm cov leeg, cov leeg yuav so.
Lub luag haujlwm ntawm calcium ion hauv cov leeg nqaij yog dab tsi?
Thaum calcium khi rau troponin, troponin hloov pauv, tshem tropomyosin los ntawm qhov chaw khi. Lub sarcoplasmic reticulum khaws cov calcium ions, uas nws tso tawm thaum cov leeg nqaij ntshiv; cov calcium ions ces pab kom lub hla-bridge nqaij kev cog lus.
calcium tseem ceeb rau cov leeg li cas?
Calcium cuam tshuam rau cov leeg by regulating contractions Qhov no suav nrog tswj lub plawv dhia vim lub plawv yog cov leeg uas tso ntshav. Calcium raug tso tawm thaum lub paj hlwb txhawb cov leeg. Calcium kuj tseem ua lub luag haujlwm hauv cov txheej txheem nyuaj ntawm cov ntshav coagulation (cov ntshav txhaws).
Puas calcium pab cov leeg loj hlob?
" Calcium regulation yog ib qho tseem ceeb ntawm cov leeg nqaij contraction thiab yog li ntawd, tsim cov leeg, "hais Jim White, tus tswv ntawm Jim White Fitness Studios hauv Virginia thiab tus cev lus rau Academy Khoom noj khoom haus thiab Dietetics.
