Qhov sib txawv tseem ceeb ntawm photosynthesis thiab cellular respiration yog photosynthesis siv carbon dioxide thiab dej los tsim cov piam thaj thiab oxygen thaum lub cellular respiration siv qabzib thiab oxygen los tsim lub zog, carbon dioxide, thiab dej.
Photosynthesis thiab cellular respiration yog ob txheej txheem cellular uas tshwm sim hauv cov kab mob thiaj li tsim tau lub zog. Photosynthesis converts lub teeb lub zog ntawm lub hnub mus rau hauv tshuaj lub zog ntawm qab zib los ntawm tso pa oxygen raws li ib tug byproduct. Ntawm qhov tod tes, cellular respiration yog cov txheej txheem biochemical uas cov hlwb tau txais lub zog los ntawm cov tshuaj sib txuas ntawm cov khoom noj molecules. Photosynthesis thiab cellular respiration yog cov txheej txheem tseem ceeb ntawm lub neej. Kab lus no qhia txog qhov txawv ntawm photosynthesis thiab cellular respiration.
Photosynthesis yog dab tsi?
Photosynthesis yog txheej txheem uas ua los ntawm photoautotrophs. Photoautotrophs tsim lawv tus kheej cov zaub mov los ntawm cov txheej txheem no. Nroj tsuag, algae, thiab cyanobacteria yog cov pab pawg tseem ceeb ntawm photoautotrophs. Thaum lub sij hawm photosynthesis, siv lub teeb lub zog ntawm lub hnub ci, carbon dioxide, thiab dej hloov mus rau hauv qabzib thiab oxygen thaum photosynthetic pigments muaj. Oxygen, uas yog ib qho tseem ceeb rau tag nrho cov muaj sia nyob, raug tso tawm rau cov huab cua raws li ib tug byproduct ntawm photosynthesis. Photosynthesis yog cov txheej txheem tseem ceeb heev uas tso cai rau lub neej mus ntxiv hauv ntiaj teb. Oxygen tsim los ntawm photosynthesis yog qhov tseem ceeb rau cov txheej txheem ntawm kev ua pa ntawm feem ntau cov tsiaj nyob hauv ntiaj teb. Carbohydrate uas tsim los ntawm photosynthesis yog hom zaub mov yooj yim tshaj plaws uas tuaj yeem ua tiav los ntawm cov kab mob muaj sia kom tau txais lub zog.
Daim duab 01: Photosynthesis
Cov kab zauv hauv qab no yog daim ntawv qhia ntau tshaj plaws ntawm kev sau cov photosynthesis:
Carbon Dioxide (6CO2) + Dej (6H2O) --hloov nrog kev pab lub teeb zog -→ Glucose (C6H12O6) + Oxygen (6 O2)
Photosynthesis tuaj yeem muab faib ua ob txoj haujlwm tseem ceeb: txheej txheem teeb tsa (lub teeb pom kev zoo) txheej txheem thiab lub teeb ywj pheej (tshem tawm tsaus nti). Lub teeb-dependent photosynthesis xav tau lub hnub ci tiag tiag kom hnov mob, thaum tsaus ntuj cov tshuaj tiv thaiv tsuas yog xav tau cov khoom ntawm lub teeb tshuaj tiv thaiv mus ntxiv. Cov tshuaj tiv thaiv lub teeb xav tau cov photons thiab dej los muab cov pa oxygen uas ua rau kev tsim cov ATP thiab NADPH. NADPH yog ib qho kev txo qis uas tuaj yeem txo nws cov hydrogen molecule.
Tsaus cov tshuaj tiv thaiv photosynthesis, tseem hu ua Calvin lub voj voog, siv Carbone dioxide thiab tsim NADPH tshiab los tsim phosphogylcerides; peb cov suab thaj tuaj yeem ua ke tom qab tsim cov suab thaj thiab cov hmoov txhuv nplej siab. Nroj tsuag khaws cov khoom qab zib thiab cov hmoov txhuv nplej siab rau hauv cov txiv hmab txiv ntoo thiab yams, thiab lwm yam rau kev siv yav tom ntej. Feem ntau lwm cov kab mob nyob yog nyob ntawm cov carbohydrates uas tsim los ntawm cov nroj tsuag los ntawm photosynthesis. Yog li ntawd, photoautotrophs ua haujlwm tseem ceeb hauv cov khoom lag luam yuav luag txhua cov khoom noj hauv ib qho chaw nyob.
Cellular Respiration yog dab tsi?
Cellular ua pa yog txheej txheem biochemical uas cov hlwb hloov cov tshuaj zog ntawm macromolecules rau hauv lub zog hauv daim ntawv ntawm ATP. Kev ua pa ntawm tes siv cov carbohydrates, rog, thiab cov proteins ua roj. Glucose yog qhov siv zog tshaj plaws hauv kev ua pa ntawm tes. Txhua yam kab mob nyob ua pa ua pa: aerobic ua pa nyob rau hauv lub xub ntiag ntawm oxygen, thiab anaerobic ua pa thaum tsis muaj oxygen. Prokaryotic hlwb nqa tawm cellular ua pa nyob rau hauv lub cytoplasm whereas eukaryotic hlwb nqa tawm cellular respiration feem ntau nyob rau hauv lub mitochondria ntawm lub cell. Hauv kev ua pa aerobic, ib qho qabzib molecule tuaj yeem tsim 36-38 molecules ntawm ATP, tab sis hauv kev ua pa anaerobic (los ntawm glycolysis thiab fermentation) tsuas yog 2 ATP molecules tuaj yeem muab tau.
Daim duab 02: Cellular Respiration
Ntxiv mus, kev ua pa ntawm tes tuaj yeem muab faib ua peb txheej txheem metabolic xws li glycolysis, Krebs cycle thiab electron thauj saw. Glycolysis tshwm sim hauv cytosol thaum lub voj voog Krebs tshwm sim hauv mitochondrial matrix. Electron thauj saw tshwm sim nyob rau hauv lub puab mitochondrial membrane. Yog tias tsis muaj oxygen, kev ua pa yuav tshwm sim los ntawm ob txoj hauv kev metabolic hauv cytosol ntawm glycolysis thiab fermentation.
Dab tsi zoo sib xws ntawm Photosynthesis thiab Cellular Respiration?
- Photosynthesis thiab cellular respiration yog cov txheej txheem tseem ceeb ntawm cov kab mob nyob.
- Tsis tas li ntawd, ob qho txheej txheem nyob ntawm ib leeg.
- Nyob rau ib leeg.
Qhov txawv ntawm Photosynthesis thiab Cellular Respiration yog dab tsi?
Photosynthesis yog txheej txheem uas hloov lub teeb lub zog rau hauv cov tshuaj lom neeg lub zog ntawm carbohydrates nyob rau hauv lub hnub ci thiab chlorophylls. Txawm li cas los xij, kev ua pa ntawm tes yog txheej txheem uas hloov cov tshuaj zog ntawm cov organic sib txuas rau hauv ATP (lub zog txiaj) txhawm rau siv nws rau txhua txoj haujlwm tshwm sim hauv cov kab mob muaj sia. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm photosynthesis thiab cellular respiration. Tsis tas li ntawd, tsuas yog photoautotrophs nqa tawm photosynthesis thaum tag nrho cov kab mob nyob ua pa tawm ntawm tes. Li no, qhov no kuj yog qhov txawv ntawm photosynthesis thiab cellular respiration.
Ntxiv mus, qhov sib txawv ntxiv ntawm photosynthesis thiab cellular respiration yog qhov photosynthesis siv carbon dioxide thiab dej thiab tsim cov piam thaj thiab oxygen thaum cellular respiration siv qabzib thiab oxygen thiab tsim carbon dioxide, dej, thiab lub zog. Tsis tas li ntawd, photosynthesis tshwm sim ntawm ob kauj ruam: cov tshuaj tiv thaiv lub teeb thiab cov tshuaj tiv thaiv tsaus. Nyob rau hauv sib piv, cellular respiration tshwm sim ntawm peb kauj ruam: glycolysis, Krebs voj voog thiab electron thauj saw. Tsis tas li ntawd, qhov chaw ntawm photosynthesis yog chloroplasts thaum lub chaw ntawm cellular respiration yog cytoplasm thiab mitochondria. Yog li, peb tuaj yeem xav txog qhov no ib yam li qhov sib txawv ntawm photosynthesis thiab cellular respiration.
Summary – Photosynthesis vs Cellular Respiration
Hauv cov ntsiab lus, ob qho tib si photosynthesis thiab cellular respiration yog cov txheej txheem tseem ceeb uas tshwm sim hauv cov kab mob nyob hauv thiaj li yuav tau txais lub zog. Txawm li cas los xij, photosynthesis khaws lub zog ntawm lub hnub ci nyob rau hauv daim ntawv ntawm cov tshuaj muaj zog hauv cov suab thaj thiab cov hmoov txhuv nplej siab thaum lub sij hawm cellular respiration ua rau cov organic tebchaw xws li qab zib thiab hmoov txhuv nplej siab thiaj li tsim tau lub zog nyob rau hauv daim ntawv ntawm ATP (lub zog txiaj). Ob qho txheej txheem no yog nyob ntawm ib leeg; tsiaj pub rau cov txiv hmab txiv ntoo uas tsim los ntawm cov nroj tsuag kom tau cov organic tebchaw rau lawv cov cellular respiration; Lawv kuj siv cov pa tawm mus rau hauv huab cua kom ua pa thaum cov nroj tsuag nyob ntawm seb cov pa roj carbon dioxide exhaled los ntawm cov tsiaj mus rau saum huab cua rau cov txheej txheem ntawm photosynthesis. Nyob rau hauv tsis muaj ib tug, txoj kev muaj sia nyob rau lwm yam drastic degraded. Yog li, qhov no xaus cov ntsiab lus ntawm qhov sib txawv ntawm photosynthesis thiab cellular respiration.
