Qhov sib txawv tseem ceeb ntawm kev ua pa thiab photosynthesis yog qhov ua pa yog cov txheej txheem biochemical uas siv cov pa oxygen thiab hloov cov zaub mov rau hauv lub zog thaum photosynthesis yog txheej txheem uas tsim cov carbohydrates thiab tso tawm oxygen rau hauv qhov chaw.
Ua pa thiab photosynthesis yog ob yam tseem ceeb tshaj plaws ntawm lub neej. Ob txoj kev ntxim nyiam no txawv ntawm ib leeg hauv ntau txoj hauv kev raws li tau tham hauv kab lus no. Feem ntau, ib qho ntawm cov txheej txheem no hloov lub zog siv tsis tau rau hauv cov zaub mov thaum lwm cov txheej txheem ua rau lub zog siv tau los ntawm cov khoom noj uas khaws cia. Tsis tas li ntawd, cov pa roj carbon dioxide tau koom nrog hauv ob qho tib si cov txheej txheem no, tab sis ntawm qhov chaw sib txawv.
Ua pa yog dab tsi?
Kev ua pa yog cov txheej txheem biochemical uas hloov cov zaub mov rau hauv lub zog nrog oxygen, thiab nws tshwm sim hauv cov hlwb ntawm txhua tus tsiaj. Hauv kev ua pa, lub zog biochemical ntawm cov zaub mov hloov mus rau adenosine triphosphate (ATP) thiab carbon dioxide raws li kev siv oxygen. Cov pa roj carbon dioxide yog cov khoom pov tseg thiab cov khoom tseem ceeb ATP yog daim ntawv siv lub zog ntawm cov kab mob. Qhov tseeb, nws yog lub zog txiaj ntawm cov tsiaj muaj sia. Yog li ntawd, kev ua pa yog txoj hauv kev tseem ceeb ntawm kev tau txais lub zog, uas yog qhov tseem ceeb los tswj tag nrho cov txheej txheem lom neeg. Yog li, nws tuaj yeem hais tau tias kev ua pa ua rau lub zog los ntawm kev hlawv cov zaub mov hauv hlwb. Qab Zib (glucose), amino acids, thiab fatty acids yog ib qho ntawm cov kev siv ua pa substrates hauv kev ua pa.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov txheej txheem ua pa yog aerobic lossis anaerobic nyob ntawm qhov kev koom tes ntawm oxygen hauv cov txheej txheem. Cov txheej txheem ua pa aerobic siv cov pa oxygen ua tus txais hluav taws xob zaum kawg thaum kev ua pa anaerobic tshwm sim thaum tsis muaj oxygen thiab siv lwm yam tshuaj xws li sulfur compounds los tsim lub zog.
Tag nrho cov txheej txheem ntawm kev ua pa aerobic suav nrog plaub kauj ruam tseem ceeb: glycolysis, citric acid voj voog (Krebs voj voog), oxidative decarboxylation ntawm pyruvate, thiab oxidative phosphorylation. Thaum kawg ntawm kev ua pa aerobic, nws tsim cov nyiaj tau los ntawm 38 ATP molecules los ntawm ib qho qabzib molecule (C6H12O. 6)..
Photosynthesis yog dab tsi?
Photosynthesis yog cov txheej txheem biochemical uas hloov lub zog ntawm lub hnub ci mus rau hauv cov organic tebchaw siv carbon dioxide. Cov pa roj carbon dioxide (CO2) reacts nrog dej (H2O) nyob rau hauv lub hnub ci los tsim cov piam thaj (C 6 H12O6) thiab oxygen (O2).
Photosynthesis tshwm sim hauv chloroplast ntawm cov hlwb ntawm cov nroj tsuag, ntsuab algae, thiab cyanobacteria. Qhov tseem ceeb tshaj plaws, photosynthesis tswj lub ntiaj teb CO2 qib ntawm qib qis thiab txhim kho O2 qib ntawm huab cua. Txawm li cas los xij, cov dej num anthropogenic tsis ntev los no muaj kev cuam tshuam rau cov photosynthetic purification ntawm CO2 hauv huab cua.

Cov xim ntsuab ntawm chlorophyll hauv chloroplast yog lub luag haujlwm rau kev ntes lub hnub ci ntawm qhov xav tau rau cov txheej txheem ntawm kev ua kom cov electrons. Muaj ob theem tseem ceeb hauv photosynthesis: cov tshuaj tiv thaiv lub teeb thiab cov tshuaj tiv thaiv tsaus. Cov tshuaj tiv thaiv lub teeb cuam tshuam nrog Z-scheme thiab dej photolysis thaum cov tshuaj tiv thaiv tsaus ntuj cuam tshuam nrog Calvin lub voj voog thiab cov pa roj carbon concentrating mechanisms. Kev ua haujlwm ntawm tag nrho cov txheej txheem ntawm photosynthesis sib txawv ntawm 3 - 6%. Txawm li cas los xij, nws nyob ntawm qhov tseem ceeb ntawm cov pa roj carbon dioxide hauv qhov chaw, lub teeb siv, thiab kub.
Dab tsi yog qhov Zoo sib xws ntawm Kev Ua pa thiab Photosynthesis?
- Ua pa thiab photosynthesis yog ob yam txheej txheem biochemical tseem ceeb tshwm sim hauv cov kab mob nyob.
- Cov pa roj carbon dioxide, oxygen, qabzib thiab dej ua lub luag haujlwm tseem ceeb hauv ob txoj haujlwm.
- Tsis tas li, lawv tshwm sim ntawm qib cellular.
- Ntxiv mus, ob txoj haujlwm tseem ceeb hauv ntiaj teb txhawm rau tswj hwm qib CO2 thiab O2.
Dab tsi yog qhov txawv ntawm Kev Ua pa thiab Photosynthesis?
Ua pa thiab photosynthesis yog ob yam txheej txheem biochemical tseem ceeb tshwm sim hauv cov kab mob nyob. Qhov sib txawv tseem ceeb ntawm kev ua pa thiab photosynthesis yog qhov ua pa hlawv cov zaub mov thiab tsim lub zog thaum photosynthesis tsim cov khoom noj los ntawm kev ntes lub hnub. Tsis tas li ntawd, kev ua pa tshwm sim hauv txhua yam kab mob uas muaj sia nyob tab sis photosynthesis tsuas yog tshwm sim hauv cov nroj tsuag, algae thiab cyanobacteria.
Ntxiv mus, qhov sib txawv ntxiv ntawm kev ua pa thiab photosynthesis yog qhov chaw uas nws tshwm sim. Kev ua pa tshwm sim hauv mitochondria thaum photosynthesis tshwm sim hauv chloroplasts. Tsis tas li ntawd, kev ua pa siv oxygen thiab tso cov pa roj carbon dioxide. Piv txwv li, photosynthesis siv carbon dioxide thiab tso pa oxygen. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm kev ua pa thiab photosynthesis.
Summary – Ua pa vs Photosynthesis
Ua pa yog txheej txheem catabolic uas hlawv zaub mov thiaj li tsim ATP. Hauv qhov sib piv, photosynthesis yog txheej txheem anabolic uas tsim cov khoom noj. Tsis tas li ntawd, kev ua pa tshwm sim hauv txhua yam kab mob. Tab sis, photosynthesis tsuas yog siv nyob rau hauv photoautotrophs xws li nroj tsuag, algae thiab cyanobacteria. Hauv eukaryotes, ua pa tshwm sim hauv mitochondria thaum photosynthesis tshwm sim hauv chloroplasts. Qhov tseem ceeb tshaj plaws, photosynthesis tso tawm oxygen thiab tswj cov qib carbon dioxide hauv cov huab cua. Yog li, qhov no qhia txog qhov sib txawv ntawm kev ua pa thiab photosynthesis.
