Assimilation hauv ib - yog dab tsi no? Piv txwv assimilation thiab dissimilation nyob rau hauv cov xwm

Assimilation hauv ib - ib tug txheej txheem uas plays ib qho tseem ceeb luag hauj lwm nyob rau hauv lub digestive system ntawm ib tug nyob kab mob. Yuav ua li cas yog nws? Wb hais tias koj noj ib pluag mov hnub no, kom tau ib qhov nqi ntawm lub zog. Tab sis tau koj puas tau xav txog yuav ua li cas cov zaub mov tau txais los ntawm lub phaj rau hauv lub cell? Thaum koj muaj ib yam dab tsi rau noj, koj lub cev yuav pib mus ua txhaum down zaub mov thaum lub sij hawm kev zom, nqus cov as-ham thiab muab lawv mus rau lub hlwb nyob rau hauv lub sij hawm ntawm assimilation, qhov uas lawv yuav siv tau rau txoj kev loj hlob thiab kev kho.

Yuav ua li cas tshwm sim tom qab ib tug noj mov?

Yuav kom to taub li cas cov kev zom thiab assimilation nyob rau hauv biology, cia peb thawj saib yuav ua li cas peb zom qub zaub mov. Xav txog qhov no raws li ib tug cheeseburger. Thaum lub sij hawm mastication tshwm sim maceration, sib tsoo thiab xa cov mov noj bolus, uas yog ces tsiv los ntawm cov hlab pas mus rau lub plab, uas muaj muaj zog acids thiab enzymes zom apart.

Carbohydrates thiab proteins (nqaij thiab bun) pib mus zom ua ntej lwm leej lwm tus. Ntxiv mus, cov hnyuv, lub sibhawm (cheese) pib cev qhuav dej ntawm lawv cov neeg lub Cheebtsam hu ua fatty acids. Thaum lub caij, digesting cheeseburger tiav. Tam sim no nws yog lub sij hawm rau assimilate cov as-ham nyob rau hauv koj lub cev tau txais.

Haum cov as-ham

Haum cov as-ham yog nqa tawm nyob rau hauv cov hnyuv, uas yog muab nrog me me lugs, uas yog hu ua microvilli. Tej yam tseem ceeb hlwb coj mus as-ham los ntawm cov hnyuv thiab pumped nws mus rau hauv cov ntshav, uas yuav muab kev pab kom lawv lub cev. Yuav kom to taub tus txheej txheem no, cia saib raws nraim li cas digestible carbohydrates.

Los ntawm lub sij hawm lub carbohydrates muaj nyob rau hauv ib lub hamburger bun, mus txog hauv cov hnyuv, lawv raug tawg cia rau hauv qab zib, lub npe hu ua glucose. Microvilli muaj me me twj uas nqus nws los ntawm lub plab hnyuv lumen, thiab yog tsiv mus rau nws epithelial hlwb. Txawm li cas los, hais tias qab zib ua rau tus so ntawm lub cev, nws yuav tsum nkag mus rau hauv cov hlab ntsha. Tus lwm sab ntawm plab hnyuv epithelial hlwb muaj lwm twj tso kua mis, uas yog tus coj hauv zib nyob rau hauv cov hlab ntsha uas nyob ib ncig ntawm cov hnyuv.

Ntau dhau lawm zib nyob rau hauv cov ntshav yuav ua tau teeb meem loj, yog li ib feem ntawm nws yog xa mus rau lub siab rau cia. Hlwb ntawm no tseem ceeb heev lub cev cia tshaj qab zib raws li glycogen. Los yeej muaj, qabzib yog tauj mus rau tag nrho cov hlwb nyob rau hauv lub cev, uas siv nws los tsim cellular zog los yog ATP, yuav tsum tau mus raws li tag nrho cov kev xav tau ntawm lub hlwb thiab tus kab mob raws li ib tug tag nrho. As-ham - nws tsis yog ib yam uas zoo tsim nyog nyob rau hauv kev txiav txim hais tias lub cev tseem noj qab nyob zoo. Heev tseem ceeb yog cov txaus kom tsawg ntawm cov dej.

Assimilation hauv ib - yog dab tsi no?

Lub lom uptake yog ib tug ua ke ntawm ob tug dab, thaum lub sij hawm uas lub hlwb yog tauj as-ham. Tus thawj yuav lub nqus ntawm cov vitamins, minerals thiab lwm yam tshuaj los ntawm cov khoom noj khoom haus. Nyob rau hauv tib neeg, qhov no yog ua li cas nrog ib lub cev (qhov ncauj zom thiab lub plab Churning) thiab tshuaj degradation (enzymes thiab acids). Qhov thib ob hu ua bioassimilation, yog ib yam tshuaj hloov ntawm tshuaj nyob rau hauv cov ntshav, siab los yog ntawm tes tsis muaj kua.

Assimilation thiab dissimilation hauv ib

Dissimilation hauv ib yog tus txheej txheem ntawm decomposition ntawm cov organic tebchaw (cov nqaijrog, Sibhawm, carbohydrates, thiab t. D.) Nyob rau ib tug yooj yim tshuaj. Kev sib sau assimilation thiab dissimilation muab ib qho kev pauv ntawm qhov teeb meem thiab lub zog, uas yog lub hauv paus ntawm lub neej thiab muaj ib tug tas mus li daim ntawv rov ntxiv ntawm cov organic tshuaj thoob plaws tus kab mob lub neej voj voog.

Dissimilation nyob rau hauv nroj tsuag thiab tsiaj muaj tus kab mob

Dissimilation nyob rau hauv cov nroj tsuag yog central rau cov metabolism hauv ib tug xov tooj ntawm cov txheej txheem, nrog rau kev ua pa thiab glycolysis. Tus tso tawm ntawm lub zog siv thiab cov kev tshwm sim ntawm cov dab yog tsim nyog rau lub hav zoov ntawm cov tseem ceeb heev tshwm sim. Ntawm cov lus kawg khoom ntawm dissimilation ua txoj hauj lwm nyob los ntawm cov dej, carbon dioxide pa roj thiab ammonia.

Yog hais tias cov tsiaj cov khoom thaum lub sij hawm cia sawv ntsug sab nraud, cov pa roj carbon dioxide nyob rau hauv cov nroj tsuag (tsis) thiab ammonia yog siv rau lub biosynthesis ntawm cov organic teeb meem thiab yog cov raw khoom rau haum. Siv dab dissimilation ntawm cov nroj tsuag txawv nyob ntawm seb cov theem ntawm ontogeny thiab kab mob nyob ntawm ntau lwm yam tseem ceeb.

Piv txwv kev lom assimilation

Lub ntsiab qhov chaw ntawm lub zog rau tag nrho lub neej nyob rau hauv lub ntiaj chaw yog hnub ci tawg. Tag nrho cov muaj tus kab mob nyob rau lub ntiaj teb yuav tsum tau muab faib mus rau hauv autotrophic thiab heterotrophic. Thawj pab pawg neeg - yog feem ntau cov nroj tsuag ntsuab, muaj peev xwm hloov radiant zog los ntawm lub hnub thiab los ntawm photosynthesis tau organic tebchaw los ntawm inorganic tshuaj.

Lwm yam uas muaj sia nyob, tsuas yog ib co kab mob uas muaj peev xwm tau txais lub zog los ntawm txoj kev tshuaj uas metabolize cov organic teeb meem twb tsim thiab siv tau raws li ib tug lub zog qhov chaw los yog raws li ib tug yam ntxwv cov ntaub ntawv uas rau constituting lub cev. Ib lub sij hawm thaum muaj yog lub feem ntau kom nquag plias thiab mob siab heev assimilation hauv ib - yog cov hluas uas muaj hnub nyoog ntawm cov tsiaj thiab cov loj hlob rau lub caij ntawm cov nroj tsuag.

Metabolism hauv: txoj kev sib sau ntawm ob dab

Metabolism hauv yog cov kev sib sau ntawm ob dab: assimilation thiab dissimilation. Mastering yog lub sum ntawm cov txheej txheem ntawm creation ntawm nyob teeb meem: uptake ntawm tshuaj nkag mus rau tus kab mob los ntawm cov ib puag ncig, tus tsim ntawm ntau tshuaj tebchaw los ntawm yooj yim thiab thiaj li nyob. Assimilation hauv ib - ib tug txheej txheem nyob rau hauv uas hlwb siv ntaub ntawv sib txawv yog hloov mus rau hauv nyob teeb meem. Dissimilation - yog kev puas tsuaj ntawm nyob qhov teeb meem, lwj, degradation ntawm tshuaj nyob rau hauv cell haiv neeg, nyob rau hauv particular protein tebchaw. Assimilation (piv txwv nyob rau hauv cov xwm - yog photosynthesis, nitrogen fixation ntawm cov av, as uptake thaum lub sij hawm kev zom) thiab dissimilation inextricably txuas. Mastering dab nrog ib qho kev nce puas, uas nyob rau hauv lem, muab cov theem rau assimilation.
