Diffusion yog tseem ceeb rau cov kab mob vim nws yog cov txheej txheem uas muaj txiaj ntsig molecules nkag mus rau hauv lub cev hlwb thiab cov khoom pov tseg raug tshem tawm. Digested zaub mov molecules (amino acids, qabzib) txav mus rau ib qho concentration gradient los ntawm txoj hnyuv mus rau cov ntshav.

Kuj paub, dab tsi yog qhov tseem ceeb ntawm diffusion hauv cov kab mob muaj sia?

Diffusion yog heev tseem ceeb rau muaj sia nyob vim nws yog ib qho tseem ceeb rau kev noj cov khoom muaj txiaj ntsig thiab tshem tawm cov khoom pov tseg. Piv txwv li, oxygen xav tau rau peb lub cev ua haujlwm, thaum carbon dioxide yuav tsum tau tshem tawm ntawm peb lub cev.

Ib tug kuj yuav nug, dab tsi yog qhov tseem ceeb ntawm diffusion thiab osmosis? Ob qho tib si diffusion thiab osmosis tsom kom sib npaug zog hauv cov hlwb thiab cov kab mob tag nrho, sib kis dej , cov as-ham thiab cov tshuaj tsim nyog los ntawm thaj chaw uas muaj cov concentration siab rau cov cheeb tsam uas muaj cov concentration tsawg.

Xav txog qhov no, dab tsi yog qhov tseem ceeb ntawm diffusion hauv cov nroj tsuag?

Hauv ob qho tib si nroj tsuag thiab tsiaj txhu, nthuav tawm yog koom nrog hauv kev txav ntawm tseem ceeb molecules rau hauv thiab tawm ntawm cov cell. Nws yog tseem ceeb rau uptake ntawm cov khoom xav tau los ntawm cov hlwb, thiab tseem tshem tawm cov khoom pov tseg uas tsim los ntawm cov hlwb.

Dab tsi yog qhov tseem ceeb ntawm diffusion ntawm gases thiab solutes?

Lub diffusion ntawm gases yog dab tsi ua rau cov pa pauv tau (koj paub, qhov uas koj ua pa rau hauv oxygen thiab ua pa tawm carbon dioxide?). Diffusion ntawm solutes yog dab tsi ua rau cov nroj tsuag cog lawv cov duab zoo (lub cell ua turgid thaum dej diffuses hauv). Nws tseem yog dab tsi enables cov nroj tsuag mus transpire.
