Qhov sib txawv tseem ceeb ntawm kev nqus thiab assimilation yog qhov nqus tau yog cov txheej txheem ntawm kev noj cov zom zom yooj yooj yim rau hauv cov hlab ntsha / lymph los ntawm txoj hnyuv villi thiab microvilli thaum assimilation yog cov txheej txheem ntawm kev sib txuas tshiab los ntawm cov molecules absorbed.
Tib neeg yog heterotrophs. Yog li ntawd, lawv siv cov khoom noj carbonic synthesized los ntawm cov kab mob autotrophic. Heterotrophic khoom noj khoom haus muaj tsib txheej txheem ua ntu zus. Lawv yog cov ingestion, digestion, absorption, assimilation thiab ejection. Ntawm no, lub plab zom mov thiab nws lub cev sib koom ua ke ua lub luag haujlwm tseem ceeb hauv kev ua tiav cov kauj ruam saum toj no. Tsis tas li ntawd, muaj qee qhov kev hloov pauv thiab kev hloov kho tshwj xeeb raws tus kwj dej hauv lub cev kom pab txhawb cov kauj ruam sib txawv ntawm cov khoom noj khoom haus heterotrophic.
Kev nqus yog dab tsi?
Absorption yog tus txheej txheem ntawm kev noj cov digested yooj yim molecules rau hauv cov hlab ntsha/lymph ntawm txoj hnyuv villi thiab microvilli. Yog li ntawd, kev nqus yuav tshwm sim hauv cov hnyuv. Noj cov zaub mov los ntawm lub qhov ncauj yog ob qho tib si mechanical thiab tshuaj digestion. Ib yam li ntawd, qhov no tshwm sim ntawm qhov chaw sib txawv hauv lub plab zom mov. Mechanical digestion mas tshwm sim nyob rau hauv lub buccal kab noj hniav vim hais tias ntawm sib tsoo cov zaub mov los ntawm cov hniav thiab sib tov ntawm tus nplaig. Nrog rau kev zom zaub mov, tshuaj digestion kuj pib ntawm lub qhov ncauj. Ntawm no, carbohydrates tau txais ib feem zom vim qhov kev ua ntawm ptyalin enzyme. Ib yam li ntawd, los ntawm cov txheej txheem ntawm cov tshuaj tiv thaiv enzymatic tshwm sim hauv kev zom zaub mov, macromolecules tawg mus rau hauv cov molecules yooj yim txhawm rau pab txhawb kev nqus.
Daim duab 01: Absorption
Kev nqus tau tshwm sim hauv cov hnyuv me. Nws yog tsim los ua kom nws qhov chaw loj tshaj plaws los ntawm folding rau hauv villi thiab microvilli. Thiab, cov qauv no pab txhawb kev nqus ntawm cov molecules yooj yim xws li amino acids, fatty acids, monosaccharides, thiab lwm yam. Ces, cov absorbed molecules nkag mus rau hauv cov hlab ntsha los yog lymph ntawm cov hlab ntsha nyob rau hauv qab villi thiab microvilli. Lymphatic system absorbs tsuas yog fatty acids thiab cholesterol molecules uas lawv tom qab tau rov qab mus rau hauv cov hlab ntsha. Absorption tshwm sim ntawm ob qho tib si nquag thiab passive thauj.
Yuav ua li cas yog assimilation?
Assimilation yog cov txheej txheem ntawm kev tsim cov tshuaj tshiab los ntawm cov molecules absorbed los ntawm cov hnyuv me. Thaum cov molecules tau nqus mus rau hauv cov hlab ntsha, lawv raug thauj thiab faib rau txhua lub cell hauv lub cev. Yog li ntawd, assimilation koom nrog kev hloov dua siab tshiab thiab kev koom ua ke ntawm cov molecules nrog cov ntaub so ntswg nyob. Nws kuj tseem tuaj yeem raug hu ua kev txhim kho ntawm macromolecules los ntawm kev yooj yim absorbed molecules.
Daim duab 02: Assimilation
Ntxiv mus, assimilation feem ntau tshwm sim hauv daim siab. Nws synthesizes tseem ceeb Cheebtsam xws li enzymes cov tshuaj hormones, nucleic acids, thiab lwm yam. Yog li ntawd, assimilation yog ib tug tseem ceeb txheej txheem los tswj cellular kev ua ub no ntawm optimum tej yam kev mob.
Dab tsi yog qhov zoo sib xws ntawm Absorption thiab assimilation?
- Ob qhov nqus thiab assimilation yog cov kauj ruam ntawm cov khoom noj khoom haus heterotrophic.
- Yuav kom tsim cov macromolecules tseem ceeb, kev nqus yuav tsum tshwm sim ua ntej assimilation.
- Tsis tas li, ob qho txheej txheem tshwm sim hauv peb lub cev.
Dab tsi yog qhov txawv ntawm Absorption thiab assimilation?
Kev nqus yog cov txheej txheem ntawm kev noj cov molecules yooj yim, uas yog tsim los ntawm kev zom zaub mov rau hauv lub cev (cov hlab ntshav / lymph) los ntawm txoj hnyuv. Ntawm qhov tod tes, assimilation yog txheej txheem ntawm kev ua cov tebchaw tshiab los ntawm cov molecules absorbed, uas tsim nyog rau kev ua haujlwm ntawm tes los yog tsim lub zog. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev nqus thiab assimilation. Thaum xav txog qhov chaw uas lawv tshwm sim, qhov nqus tau tshwm sim feem ntau hauv cov hnyuv me thaum assimilation tshwm sim hauv daim siab. Li no, qhov no yog lwm qhov sib txawv ntawm kev nqus thiab assimilation.
Tsis tas li ntawd, thaum lub sij hawm nqus, cov as-ham ntxiv rau hauv cov hlab ntsha tab sis, thaum lub sij hawm assimilation, molecules raug tshem tawm ntawm cov hlab ntsha los ntawm cov hlwb sib txawv. Yog li, nws kuj yog qhov sib txawv ntawm kev nqus thiab assimilation.
Summary – Absorption vs Assimilation
Ob qhov nqus thiab assimilation yog cov kauj ruam ntawm cov khoom noj khoom haus heterotrophic. Qhov sib txawv tseem ceeb ntawm kev nqus thiab assimilation yog qhov nqus yog cov txheej txheem ntawm kev zom cov molecules yooj yim rau hauv cov hlab ntsha / lymphatic ntawm txoj hnyuv villi thiab microvilli thaum assimilation yog cov txheej txheem ntawm kev sib txuas tshiab los ntawm cov molecules absorbed. Tsis tas li ntawd, kev nqus tau tshwm sim los ntawm kev thauj mus los ntawm kev nquag thiab passive thiab tshwm sim feem ntau hauv cov hnyuv. Ntawm qhov tod tes, assimilation feem ntau tshwm sim hauv daim siab. Tsis tas li ntawd, nws pab kev loj hlob ntawm tes thiab kev loj hlob nrog rau kev tsim cov cell tshiab. Qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm kev nqus thiab assimilation.
