Qhov sib txawv tseem ceeb ntawm Krebs thiab Calvin lub voj voog yog tias Krebs lub voj voog yog ib feem ntawm cov txheej txheem ua pa aerobic uas ua rau ATP thaum Calvin lub voj voog yog ib feem ntawm photosynthesis uas tsim cov khoom noj los ntawm kev noj ATP.
Biochemical pathways yog cov txheej txheem tseem ceeb heev los tswj lub neej hauv ntiaj teb. Krebs thiab Calvin cycles yog ob txoj hauv kev biochemical tseem ceeb uas tshwm sim hauv cov organelles ntawm cov hlwb. Ob qhov txheej txheem no yog cyclic, tab sis muaj ntau qhov sib txawv ntawm lawv. Cov chaw uas cov txheej txheem no tshwm sim thiab kev siv lossis kev tsim hluav taws xob sib txawv ntawm ib leeg.
Krebs Cycle yog dab tsi?
Krebs lub voj voog tsuas yog ib feem ntawm cov txheej txheem ua pa aerobic uas tshwm sim hauv cov hlwb. Kev tsim cov pa roj carbon dioxide thiab ATP (adenosine triphosphate) nrog rau lwm cov khoom siv los ntawm cov khoom tshwm sim thaum lub sij hawm tag nrho cov txheej txheem ntawm cellular respiration thiab Krebs voj voog yog ib qho tseem ceeb ntawm qhov ntawd. Cov kab mob khaws cia lub zog hauv daim ntawv ntawm ATP. Cov txheej txheem paub los ntawm ntau lub npe xws li Citric acid cycle, Tricarboxylic acid cycle, lossis Krebs cycle. Tab sis tag nrho cov npe no hais txog ib txheej txheem. Txij li cov kab mob feem ntau yog aerobic (nroj tsuag, tsiaj txhu, kab mob), Krebs lub voj voog tshwm sim hauv txhua yam kab mob aerobic.
Daim duab 01: Krebs cycle
Krebs lub voj voog yog ib kauj ruam tseem ceeb hauv txoj kev ua pa uas Acetyl coenzyme A tau tawg nrog oxygen uas ua rau tso tawm lub zog los tsim ATP molecules. Txawm li cas los xij, Acetyl coenzyme A yog tsim los ntawm kev ua pa substrates xws li qabzib, amino acid, lossis rog. Cov txheej txheem no tsis ua haujlwm thaum tsis muaj cov pa oxygen thiab cov pa substrates tau tawg hauv lub voj voog Krebs. Txij li thaum lub voj voog no suav nrog ob qho kev tawg (catabolic) thiab kev sib txuas (anabolic) cov kauj ruam, nws yog lub npe hu ua amphibolic txoj kev. Tag nrho cov txheej txheem tau muaj npe tom qab Hans Krebs, uas yeej Nobel nqi zog xyoo 1953 rau kev tshawb pom ntawm nws.
Calvin Cycle yog dab tsi?
Calvin lub voj voog yog ib kauj ruam tseem ceeb hauv qhov tsaus ntuj cov tshuaj tiv thaiv ntawm photosynthesis uas tshwm sim hauv stroma ntawm chloroplast ntawm cov nroj tsuag ntsuab. Nws yog txoj hauv kev biochemical cyclic uas pib nrog kev siv cov pa roj carbon dioxide thiab tsim cov pa oxygen. Raws li lub ntsiab txhais, Calvin voj voog yog ib txheej ntawm cov kev tshwm sim tshwm sim nyob rau hauv qhov tsaus ntuj cov tshuaj tiv thaiv ntawm photosynthesis, uas txhais tau hais tias nws tsis xav tau lub hnub ci. Kev ua kom cov electrons tsis tshwm sim hauv Calvin voj voog. Tab sis lub zog tsim nyog rau cov txheej txheem tau ua tiav los ntawm kev noj ATP.
Daim duab 02: Calvin cycle
tag nrho, lub voj voog no yog txoj hauv kev anabolic, uas tsim cov piam thaj los ntawm carbon dioxide thiab dej. Txawm li cas los xij, cov carbohydrates uas tsim nyob rau hauv lub voj voog Calvin tsis yog cov suab thaj hexose (qabzib nrog rau 6 carbons) raws li qhov kev tshawb pom tseeb; lawv yog triose (peb-carbon) qab zib phosphates, aka triose phosphates. Tom qab ntawd, nws ua rau tsim cov suab thaj hexose hauv mitochondria.
Dab tsi zoo sib xws ntawm Krebs thiab Calvin Cycle?
- Krebs lub voj voog thiab Calvin lub voj voog yog ob txoj hauv kev tseem ceeb ntawm biochemical.
- CO2 thiab ATP koom nrog ob txheej txheem.
- Ob leeg tshwm sim hauv cov nroj tsuag.
- Ob leeg yog cov txheej txheem cyclic uas tshwm sim hauv cov hlwb.
Qhov txawv ntawm Krebs thiab Calvin Cycle yog dab tsi?
Krebs lub voj voog yog ib feem ntawm cov txheej txheem ua pa aerobic thaum Calvin lub voj voog yog ib feem ntawm photosynthesis. Yav dhau los yog txheej txheem catabolic thaum kawg yog txheej txheem anabolic. Ntxiv mus, Krebs lub voj voog tshwm sim hauv matrix ntawm mitochondria thaum Calvin lub voj voog tshwm sim hauv stroma ntawm chloroplasts. Krebs lub voj voog tshwm sim hauv cov kab mob aerobic. Nws tsim ATP thiab CO2. Qhov tseem ceeb tshaj plaws, nws tshwm sim thaum muaj oxygen. Txawm li cas los xij, Calvin lub voj voog tsuas yog siv hauv cov nroj tsuag xwb. Nws siv ATP thiab CO 2 thiab tsim cov piam thaj. Tsis tas li ntawd, cov txheej txheem no tsis xav tau oxygen.
Summary
Krebs cycle thiab Calvin cycle yog ob txoj hauv kev tseem ceeb ntawm biochemical. Krebs lub voj voog tsim lub zog hauv daim ntawv ntawm ATP. Nws rhuav tshem cov piam thaj hauv qhov muaj oxygen. Cov txheej txheem no tshwm sim hauv txhua yam kab mob aerobic nrog rau cov nroj tsuag. Calvin voj voog yog ib feem ntawm photosynthesis. Nws yog lub npe hu ua cov tshuaj tiv thaiv tsaus ntuj thiab vim nws tsis muaj kev ywj pheej ntawm lub hnub, tsis zoo li cov tshuaj tiv thaiv lub teeb. Nws tsim cov piam thaj siv CO2 thiab ATP. Qhov no yog qhov txawv ntawm Krebs cycle thiab Calvin cycle.
