Metabolism vs Catabolism
Nws yuav yog ib qho tseem ceeb heev kom nkag siab qhov sib txawv ntawm cov metabolism thiab catabolism, vim cov no feem ntau nkag siab cov ntsiab lus yuam kev. Feem ntau, feem ntau ntawm cov tub ntxhais kawm tsis nyiam kawm physiology vim muaj teeb meem hauv kev nkag siab txog txoj hauv kev biochemical nyuaj heev. Txawm li cas los xij, yog tias tag nrho cov txheej txheem tau nkag siab nrog kev nkag siab zoo, cov txheej txheem metabolic no yuav yooj yim me ntsis ua raws. Yog li ntawd, tsab xov xwm no yuav yog ib qho tseem ceeb rau txhua tus neeg uas tsis nyob rau hauv physiology, raws li nws luv luv piav qhia txog dab tsi yog txhais los ntawm metabolism thiab catabolism cais. Tsis tas li ntawd, qhov nthuav qhia sib piv ntawm ob qho kev kawm yuav nthuav ua raws.
YMetabolism
Metabolism yog ib qho tseem ceeb heev ntawm cov tshuaj biochemical tshwm sim, txhawb nqa lub neej ntawm cov kab mob. Cov txheej txheem metabolic yog qhov tseem ceeb los tswj kev loj hlob thiab kev loj hlob ntawm cov kab mob, thiab tshem tawm lub zog los ntawm txoj hauv kev metabolic. Metabolism feem ntau yog tsim los ntawm ob txheej txheem loj hu ua catabolism thiab anabolism, uas yog lub luag haujlwm rau kev sau thiab siv zog. Tsis tas li ntawd, cov organic teeb meem tau tawg los ntawm cov txheej txheem catabolic ntawm kev zom zaub mov thiab cov no raug hlawv los ntawm kev ua pa ntawm tes kom rho tawm lub zog. Cov txheej txheem anabolic yog ua los ntawm kev siv lub zog los ntawm catabolism los tsim cov khoom tseem ceeb viz. cov proteins thiab nucleic acids los txhawb lub neej hauv lub cev. Cov tshuaj tiv thaiv kab mob metabolic tau teeb tsa zoo raws li txoj hauv kev, uas tswj tau siv cov tshuaj hormones thiab enzymes. Raws li cov metabolism ntawm cov kab mob sib txawv tau raug tshawb pom, nws tau pom tias cov txheej txheem metabolic no zoo sib xws txawm tias nyob hauv hom tshwj xeeb. Ecology thiab evolutionary biology muab cov lus piav qhia rau qhov zoo sib xws no. Qhov ntawd txhais tau hais tias lub peev xwm ntawm kev ua haujlwm metabolic txiav txim siab qhov kev ruaj khov ntawm lub neej ntawm ib yam kabmob.
Catabolism
Nyob rau hauv kev nkag siab catabolism, nws yuav yog qhov zoo tshaj plaws los txiav txim siab tag nrho cov txheej txheem metabolic, thiab cov molecules tau raug hluav taws xob los ua kom lub zog. Kev ua pa ntawm tes yog cov txheej txheem catabolic, thiab feem ntau cov piam thaj thiab cov rog tau hnov mob nrog oxygen rau hlawv kom tso tawm lub zog li ATP (adenosine triphosphate). Feem ntau, catabolism ua haujlwm ntawm kev hlawv cov monosaccharaides thiab rog, thiab tsawg heev ntawm cov proteins lossis amino acids yog siv los hlawv rau kev ntes lub zog. Catabolism yog txheej txheem oxidation, thaum lub sij hawm ib feem ntawm lub zog yog tso tawm thaum tshav kub kub. Lub generated cua sov los ntawm catabolism yog ib qho tseem ceeb rau kev saib xyuas ntawm lub cev kub. Cov pa roj carbon dioxide yog cov khoom pov tseg tseem ceeb ntawm kev ua pa ntawm tes los yog catabolism. Cov khoom pov tseg no raug xa mus rau hauv cov hlab ntsha ntawm cov hlab ntsha ntawm capillaries, thiab tom qab ntawd cov khoom no raug xa mus rau hauv lub ntsws kom ua pa tawm. Kev loj hlob thiab kev loj hlob ntawm cov hlwb ntawm cov kab mob yuav tsum muaj ntau ntawm ATPs, thiab tag nrho cov kev xav tau ntawm ATP tau ua tiav los ntawm kev ua pa ntawm tes. Yog li ntawd, catabolism yog qhov tseem ceeb hauv kev tsim lub zog. Hauv lwm lo lus, catabolism yog ib qho tseem ceeb ntawm cov txheej txheem metabolic kom tshem tawm cov tshuaj zog los ntawm cov khoom noj.
Dab tsi yog qhov txawv ntawm Metabolism thiab Catabolism?
• Catabolism yog ib hom metabolism. Hauv lwm lo lus, catabolism yog ib qho ntawm qhov metabolism yog sau ntawm ob yam.
• Lub zog raug rho tawm lossis khaws cia hauv catabolism, tab sis cov metabolism hauv kev noj, nrog rau kev sau lub zog.
• Catabolic tus nqi siab dua thaum tus neeg siv zog siv zog, qhov metabolic tus nqi siab dua txhua zaus thaum ob qho tib si catabolism thiab anabolism tshwm sim.
• Cov txheej txheem Catabolic zoo li rhuav tshem cov zaub mov rau hauv me me monomers thiab siv cov khoom noj uas khaws cia los tsim lub zog, thaum tag nrho cov txheej txheem metabolic zoo li tsim, kho, thiab muab cov ntaub so ntswg thiab lub cev los ntawm kev tsim thiab siv. lub zog.
