Aerobic Respiration vs Anaerobic Ua pa
Ua pa feem ntau yog tsim lub zog hauv daim ntawv ntawm adenosine triphosphate (ATP) los ntawm kev hlawv cov zaub mov nrog oxygen, tab sis muaj lwm hom kev ua pa tshwm sim thaum tsis muaj oxygen hu ua anaerobic respiration. Muaj ntau qhov sib txawv ntawm ob hom kev ua pa tseem ceeb nrog rau txoj hauv kev biochemical nrog rau qhov ntim ntawm lub zog tsim.
Aerobic Respiration yog dab tsi?
Raws li lub ntsiab lus, kev ua pa aerobic yog ib txheej txheej xwm uas tshwm sim hauv lub hlwb ntawm cov kab mob, tsim ATP los ntawm kev hlawv cov zaub mov hauv qhov muaj oxygen. ATP yog daim ntawv zoo tshaj plaws los khaws lub zog hauv cov hlwb. Tom qab tag nrho cov txheej txheem ntawm kev ua pa aerobic, carbon dioxide yog tsim los ua cov khoom pov tseg. Qab Zib (glucose), amino acids, thiab fatty acids yog ib qho ntawm cov neeg siv ua pa substrates hauv kev ua pa. Cov txheej txheem ua pa aerobic siv cov pa oxygen ua qhov kawg electron txais. Tag nrho cov txheej txheem ntawm kev ua pa muaj plaub theem tseem ceeb hu ua glycolysis, oxidative decarboxylation ntawm pyruvate, citric acid voj voog (Krebs cycle), thiab oxidative phosphorylation. Tom qab tag nrho cov txheej txheem tau ua tiav lawm, yuav muaj 38 ATP molecules uas tsim los ntawm ib lub qabzib molecule (C6H12O 6). Txawm li cas los xij, vim yog cov kua dej xau thiab kev siv zog siv hauv kev txav qee cov molecules thaum lub sijhawm ua haujlwm, cov khoom tsim tawm tau txwv rau ib ncig ntawm 30 ATP molecules los ntawm ib qho qabzib molecule. Qhov loj ntawm txoj kev no loj heev; muaj ntau lab lab ntawm ATP molecules uas tsim los ntawm kev ua pa aerobic ntawm tag nrho cov naj npawb ntawm cov hlwb hauv lub cev, thiab cov pa oxygen ntau heev yog xav tau thaum tib cov pa roj carbon dioxide tsim tawm. Tag nrho cov kev xav tau thiab kev tsim khoom no tau txhawb nqa los ntawm kev ua pa sab nraud ntawm qhov nqus pa thiab nqus pa nrog kev txhawb nqa ntawm cov hlab ntsha kom thauj cov pa oxygen thiab carbon dioxide nce thiab nqis.
Anaerobic Respiration yog dab tsi?
Ua pa yog qhov tseem ceeb kom tau txais lub zog; Txawm li cas los xij, tsis yog txhua qhov chaw hauv ntiaj teb muaj cov pa oxygen, thiab qhov ntawd xav kom cov kab mob hloov pauv nrog cov txheej txheem sib txawv kom thiaj li nyob hauv ib puag ncig zoo li no. Kev ua pa anaerobic yog ib txoj hauv kev ntawm kev rho tawm lub zog los ntawm cov ntaub ntawv organic siv lwm cov tshuaj viz. sulphate los yog nitrate compounds raws li qhov kawg electron txais nyob rau hauv cov txheej txheem. Tsis tas li ntawd, cov khoom siv hluav taws xob ntawm lub davhlau ya nyob twg no tsis tshua muaj txiaj ntsig hauv lawv cov peev xwm txo qis thiab tsuas tuaj yeem tsim ob peb ATP molecules rau ib cov piam thaj molecule. Feem ntau, cov khoom pov tseg yog sulfides, nitrites, lossis methane thiab cov ntxhiab tsw tsw zoo rau tib neeg thiab lwm yam tsiaj feem ntau. Lactic acid yog lwm cov pov tseg uas tsim los ntawm kev ua pa anaerobic. Nws yog qhov nthuav kom paub tias kev ua pa anaerobic tuaj yeem tshwm sim hauv tib neeg lub cev ib yam nkaus, tshwj xeeb tshaj yog thaum muaj kev xav tau ntau ntawm oxygen los ua haujlwm cov leeg nqaij sai. Hauv cov xwm txheej zoo li no, lactic acid yog tsim, thiab ua rau cov leeg mob. Kev ua pa anaerobic yog ib qho piv txwv nrog fermentation, tshwj xeeb tshaj yog nyob rau hauv txoj kev glycolytic, tab sis ethanol thiab carbon dioxide yog tsim los ua cov khoom pov tseg hauv fermentation.
Qhov txawv ntawm Aerobic Respiration thiab Anaerobic Respiration yog dab tsi?
• Oxygen koom nrog hauv kev ua pa aerobic tab sis tsis nyob hauv kev ua pa anaerobic.
• Lub zog yielding efficiency yog ntau dua nyob rau hauv aerobic respiration dua nyob rau hauv anaerobic ua pa.
• Ntawm cov kab mob, kev ua pa aerobic ntau dua li kev ua pa anaerobic.
• Cov khoom pov tseg txawv raws li hom davhlau ya nyob twg electron txais hauv kev ua pa anaerobic, whereas carbon dioxide yog cov khib nyiab loj hauv kev ua pa aerobic.
• Kev ua pa aerobic pab tswj cov pa oxygen hauv huab cua thaum anaerobic ua pa pab tswj lub voj voog carbon, nitrogen voj voog, thiab ntau lwm yam.
