Aerobic vs Anaerobic Metabolism
Cell metabolism yog txheej txheem ntawm hloov cov carbohydrates, rog, thiab cov proteins rau hauv lub zog xav tau los ntawm cov hlwb. Thaum lub sij hawm cell metabolism hauv, lub zog yog khaws cia nyob rau hauv high-zog phosphate bonds ntawm adenosine triphosphate molecules (ATP), uas ua hauj lwm raws li lub zog txiaj ntawm cov hlwb. Raws li qhov xav tau ntawm cov pa oxygen thaum lub sij hawm tsim cov ATP, muaj ob hom loj ntawm cov metabolism hauv lub cell; uas yog, aerobic thiab anaerobic. Tawm ntawm peb txoj hauv kev yooj yim metabolic, tsuas yog glycolysis raug suav tias yog cov metabolism hauv anaerobic, qhov seem suav nrog citric acid voj voog (Krebs voj voog) thiab cov saw hlau thauj hluav taws xob raug suav tias yog aerobic metabolism.
Aerobic Metabolism
Aerobic metabolism tshwm sim thaum muaj cov pa oxygen. Nws tshwm sim nyob rau hauv lub cell mitochondria thiab lub luag hauj lwm rau cov khoom ntawm 90% ntawm lub cev xav tau lub zog. Thaum lub sij hawm aerobic metabolism, tag nrho cov hauv paus substrate suav nrog carbohydrates, rog, thiab cov protein tau tawg thiab ua ke nrog cov pa oxygen molecular los tsim lub zog thaum tso cov pa roj carbon dioxide thiab dej ua cov khoom kawg. Feem ntau, oxidative metabolism tsim ze li ntawm 150 mus rau 300 mL dej hauv 24 teev ntawm lub sijhawm. Muaj ob txoj hauv kev koom nrog hauv aerobic metabolism; citric acid voj voog; uas tshwm sim nyob rau hauv lub matrix ntawm mitochondria, thiab electron thauj saw; uas tshwm sim nyob rau hauv lub electron thauj system nyob rau hauv lub puab mitochondrial membrane.
Anaerobic Metabolism
Anaerobic metabolism tsis xav tau oxygen rau kev tsim ATP. Nws tshwm sim los ntawm glycolysis, cov txheej txheem uas lub zog yog liberated los ntawm qabzib. Anaerobic metabolism hauv kev ua tau zoo yog tsawg, thiab tsim cov ATP tsawg thaum piv rau aerobic metabolism. Glycolysis tshwm sim hauv cytoplasm thiab tsis xav tau ib qho organelle. Yog li, nws yog ib qho tseem ceeb ntawm cov kab mob uas tsis muaj mitochondria xws li prokaryotes. Cov khoom kawg ntawm aerobic metabolism yog lactic acid, uas tej zaum yuav muaj teeb meem rau lub cev.
Aerobic vs Anaerobic Metabolism
• Aerobic metabolism yuav tsum tau oxygen, whereas anaerobic metabolism tsis.
• Anaerobic metabolism tsis tuaj yeem txuas ntxiv mus tsis kawg. Hauv qhov sib piv, aerobic metabolism tuaj yeem txuas ntxiv mus ib txhis, tsuas yog nyob rau hauv cov txheej txheem theoretical.
• Carbohydrate, rog, thiab proteins yog siv los ua qhov chaw ntawm aerobic metabolism thaum tsuas yog carbohydrate koom tes rau anaerobic metabolism.
• Aerobic metabolism cuam tshuam nrog kev ua haujlwm qis mus rau nruab nrab, thaum cov metabolism hauv anaerobic tsuas yog ua haujlwm siab xwb.
• Anaerobic metabolism tshwm sim hauv cytoplasm ntawm cov hlwb thaum aerobic metabolism tshwm sim hauv mitochondria.
• Aerobic metabolism ua rau lub zog ntau dua li cov metabolism hauv anaerobic yog tias tib cov nyiaj ntawm tib lub substrate.
• Glycolysis yog txoj hauv kev anaerobic metabolic, whereas citric acid voj voog thiab electron thauj saw yog aerobic metabolic txoj kev.
• Aerobic metabolism pab ntau dua (kwv yees li 90%) rau kev muab lub zog thaum anaerobic metabolism pab tsawg.
• Cov khoom kawg ntawm anaerobic metabolism yog lactic acid thaum cov metabolism hauv aerobic yog carbon dioxide thiab dej.
