Qhov sib txawv tseem ceeb ntawm kev ua pa thiab combustion yog qhov ua pa yog oxidation ntawm cov piam thaj kom tso tawm lub zog lossis tsim ATP, thaum lub combustion yog qhov kub ntawm ib yam dab tsi los ntawm kev muab cov cua sov sab nraud kom tau txais lub zog.
Cov kab mob nyob hauv xav tau lub zog los ua haujlwm ntawm tes. Qee cov txheej txheem tshwm sim yam tsis siv lub zog, tab sis feem ntau cov txheej txheem ntawm tes siv lub zog. Cellular respiration yog cov txheej txheem uas tsim cellular zog, feem ntau nyob rau hauv daim ntawv ntawm ATP. Glucose yog lub zog tseem ceeb hauv cov txheej txheem no. Thaum ua pa, ATP molecules yog tsim los ntawm oxidation ntawm qabzib molecules nyob rau hauv lub xub ntiag ntawm oxygen.combustion kuj yog ib txoj kev uas tsim lub zog tab sis nyob rau hauv daim ntawv ntawm tshav kub. Nws yuav tsum tau muab cov cua sov sab nraud. Yog li ntawd, kev ua pa thiab combustion txawv ntawm ib leeg.
Ua pa yog dab tsi?
Kev ua pa yog ib txheej txheem uas muaj cov tshuaj tiv thaiv ua ke nrog oxidation thiab txo cov tshuaj tiv thaiv thiab hloov hluav taws xob. Thaum kawg ntawm kev ua pa, cov kab mob tsim lub zog hauv daim ntawv ntawm ATP (lub zog txiaj ntawm cov hlwb) los siv rau lawv cov txheej txheem metabolic. Kev ua pa tshwm sim thaum muaj cov pa oxygen thiab thaum tsis muaj oxygen. Raws li qhov ntawd, ua pa tuaj yeem ua pa aerobic lossis ua pa anaerobic.
Thaum lub sijhawm ua pa aerobic, cov pa oxygen molecules ua raws li cov khoom siv hluav taws xob zaum kawg thiab txo kom tsim dej. Qhov no tsim ib qho electrochemical gradient uas tsav ATP synthesis. Kev ua pa aerobic muaj peb theem tseem ceeb, nyob rau hauv qhov kev hloov pauv ntawm cov pa roj carbon molecules tshwm sim los ntawm cov enzyme-catalyzed cov tshuaj tiv thaiv kom tawm los ATP. Thawj theem tshwm sim rau ob qho tib si aerobes thiab anaerobes yog txoj hauv kev glycolytic, uas tsim ob lub pyruvate molecules los ntawm cov piam thaj molecule. Ntawm no, qhov kev hloov pauv no ua rau ob lub ATP molecules thiab ob lub NADH molecules.

theem thib ob yog lub voj voog tricarboxylic acid (TCA) lossis Krebs lub voj voog, uas yog lub hauv paus hub, qhov nruab nrab ntawm txhua txoj hauv kev metabolic koom ua ke los pab txhawb kev tsim hluav taws xob los ntawm kev tsim NADH, FADH2 thiab ob lub molecules ntawm CO 2 ntawm oxidation-txo cov tshuaj tiv thaiv. Lub voj voog TCA tsuas yog siv qhov chaw hauv aerobes. Hauv ob qhov txheej txheem no (glycolysis thiab Krebs lub voj voog), substrate-theem phosphorylation yuav siv qhov chaw los tsim lub zog.
theem kawg yog cov saw hlau thauj hluav taws xob lossis oxidative phosphorylation uas tshwm sim nyob rau hauv daim nyias nyias ntawm mitochondria. Cov txheej txheem no phosphorylates ADP los ua ke ATP los ntawm kev xa cov hluav taws xob raws li cov saw hlau thauj khoom. Nws siv NADH electron cab kuj thiab ATP synthase enzyme rau kev tsim ntawm ATP. Oxidative phosphorylation xav tau cov pa oxygen molecular raws li qhov kawg electron txais. Li no, oxidative phosphorylation yog ua tau tsuas yog nyob rau hauv aerobic tej yam kev mob, thiab nws ua tau ntau dua ntawm ATP nyob rau hauv cov kab mob aerobic.
Dab tsi yog combustion?
Combustion yog qhov hlawv ntawm ib yam dab tsi los tsim lub zog, feem ntau nyob rau hauv daim ntawv ntawm tshav kub. Nws tsis tshwm sim hauv cov cell nyob. Nws yuav tsum tau muab cov cua sov sab nraud. Yog li ntawd, thaum muab cua sov, nws tshwm sim sai heev nyob rau hauv ib tug uncontrolled yam, ua kom sov ib zaug.
Daim duab 02: Kev sib xyaw ua ke
Combustion tsis xav tau enzymes thiab lwm yam tshuaj. Qhov tseeb, nws yog cov txheej txheem tsis-cellular uas tsis tsim cov khoom nruab nrab. Ntxiv mus, combustion tshwm sim thaum tsis muaj dej, tsis zoo li ua pa. Kev hlawv cov roj kom tau txais lub zog yog ib qho piv txwv nrov ntawm kev sib txuas. combustion yog ib tug txheej txheem nyob rau hauv foob pob ua ntxaij cav.
Dab tsi yog qhov zoo sib xws ntawm Kev Ua pa thiab combustion?
- Ob leeg ua pa thiab combustion tsim lub zog.
- Lawv siv oxygen.
- Kub yog tsim nyob rau hauv ob txheej txheem.
Qhov txawv ntawm Kev Ua pa thiab combustion yog dab tsi?
Kev ua pa yog cov txheej txheem uas tsim ATP lossis tshuaj lom neeg lub zog hauv cov hlwb los ntawm kev rhuav tshem cov piam thaj molecules. Hauv qhov sib piv, combustion yog qhov hlawv ntawm ib yam dab tsi los tsim lub zog. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev ua pa thiab combustion. Tsis tas li ntawd, kev ua pa yog cov txheej txheem ntawm tes uas ua rau qeeb qeeb hauv kev tswj tau, thaum combustion yog cov txheej txheem uas tsis yog cellular uas tshwm sim sai heev hauv qhov tsis tuaj yeem tswj tau.
Cov lus qhia hauv qab no qhia txog qhov sib txawv ntawm kev ua pa thiab combustion.
Summary – Ua pa vs Combustion
Kev ua pa thiab combustion yog ob txheej txheem uas tsim kom muaj zog. Kev ua pa ua rau lub zog tshuaj lom neeg feem ntau nyob rau hauv daim ntawv ntawm ATP, uas tuaj yeem siv rau kev ua haujlwm ntawm tes; combustion tsim lub zog nyob rau hauv daim ntawv ntawm tshav kub. Tsis tas li ntawd, kev ua pa yog ib qho txheej txheem ntawm tes uas tshwm sim nrog kev pab ntawm cov tshuaj sib txawv xws li enzymes, thaum combustion tshwm sim vim yog cov khoom cua sov sab nraud. Tsis tas li ntawd, kev ua pa yog ib qho qeeb thiab tswj tau, thaum combustion yog txheej txheem ceev thiab tswj tsis tau. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm kev ua pa thiab combustion.
