Ib lub siab gradient muaj tshwm sim thaum lub siab ntau dua ntawm cov kua dej sib cais los ntawm qhov qis dua, los ntawm ib daim nyias nyias.
Vim li cas qhov concentration gradient tseem ceeb?
Qhov no yog vim qhov kev txav mus los ntawm cov moleculesQhov sib txawv ntawm qhov sib txawv ntawm cov khoom nruab nrab ntawm ob qhov chaw hu ua qhov concentration gradient. Qhov sib txawv loj dua, qhov steeper qhov concentration gradient thiab ceev cov molecules ntawm ib yam khoom yuav diffuse.
Lub luag haujlwm ntawm qhov concentration gradient hauv kev nthuav dav yog dab tsi?
Qhov concentration gradient yog li ntawd sawv cev rau lub tswvyim uas, ib yam li lub pob yob nqes nqes, thaum diffusion molecules txav mus rau qhov concentration gradientHigh concentration gradients yuav ua rau ntau dua ntawm diffusion. Raws li cov molecules txav lub gradient evens tawm mus txog rau thaum equilibrium.
Kev concentration gradients ua haujlwm li cas?
A concentration gradient tshwm sim thaum lub concentration ntawm cov hais yog siab dua nyob rau hauv ib cheeb tsam dua lwm tusNyob rau hauv passive thauj, hais yuav diffuse down ib tug concentration gradient, los ntawm cov cheeb tsam ntawm siab concentration mus rau cov cheeb tsam. ntawm qis concentration, kom txog thaum lawv sib npaug spaced.
Dab tsi yog qhov concentration gradient zoo ib yam li?
Zoo ib yam li yooj yim diffusion, nws yog tsav los ntawm kev sib xyaw ua ke thiab qhov sib npaug yog tau txais thaum tsis muaj kev txav ntawm cov molecules ntawm ob thaj chaw. Feem ntau, txawm li cas los xij, qhov concentration gradient tsis txaus hauv kev thauj mus los.
