Yog tias muaj cov pa oxygen, kev ua pa ntawm tes hloov lub zog los ntawm ib qho molecule ntawm qabzib mus rau 38 molecules ntawm ATP, tso carbon dioxide thiab dej. pov tseg.
Tsis tas li cov lus nug yog, cov khoom ntawm cov khoom siv hluav taws xob thauj khoom yog dab tsi?
Cov khoom kawg ntawm electron thauj saw yog dej thiab ATP. Ib tug xov tooj ntawm cov tebchaw nruab nrab ntawm lub voj voog citric acid tuaj yeem hloov mus rau hauv anabolism ntawm lwm cov biochemical molecules, xws li cov amino acids tsis tseem ceeb, suab thaj, thiab lipids.
Qhov thib ob, dab tsi nkag mus rau hauv thiab tawm ntawm cov saw hlau thauj electron? 2 CO2 thiab 2 ATP tawm los , nrog rau 6 NADH, thiab 2 FADH2. Dab tsi mus rau hauv electron thauj saw ? Cov electrons "poob" txhawm rau tso H + hla ib daim nyias nyias, thiab H + tsim ATP thaum lawv hla rov qab. Nyob rau hauv photosynthesis, lub electron tuaj los ntawm dej; hauv kev ua pa, lub electron tuaj los ntawm zaub mov.
Tom qab, lo lus nug yog, dab tsi yog cov khoom ntawm thawj electron thauj saw?
Feem ntau eukaryotic hlwb muaj mitochondria, uas tsim ATP los ntawm cov khoom ntawm citric acid voj voog, fatty acid oxidation, thiab amino acid oxidation. Ntawm mitochondrial inner membrane, electrons los ntawm NADH thiab FADH2 dhau los ntawm electron thauj saw mus rau oxygen, uas yog txo rau hauv dej.
Dab tsi yog cov khoom pov tseg ntawm cellular respiration?
Feem ntau ntawm cov kauj ruam ntawm kev ua pa ntawm tes muaj nyob rau hauv mitochondria. Oxygen thiab qabzib yog ob qho tib si reactants hauv cov txheej txheem ntawm kev ua pa ntawm tes. Cov khoom tseem ceeb ntawm kev ua pa ntawm tes yog ATP; cov khoom pov tseg suav nrog carbon dioxide thiab dej.

Dab tsi yog cov khoom pov tseg ntawm cov tshuaj tiv thaiv lub teeb?
Dej, thaum tawg, ua rau oxygen, hydrogen, thiab electrons. Cov electrons txav los ntawm cov qauv hauv chloroplasts thiab los ntawm chemiosmosis, ua ATP. Cov hydrogen hloov mus rau NADPH uas yog tom qab ntawd siv rau hauv cov tshuaj tiv thaiv lub teeb. Oxygen diffuses tawm ntawm cov nroj tsuag raws li cov khoom pov tseg ntawm photosynthesis
Dab tsi pov thawj siv cov duab ntawm lub dav hlau sib koom ua pov thawj cov khoom geometric?
Cov ntaub ntawv pov thawj uas siv cov duab ntawm lub dav hlau sib koom ua pov thawj geometric zog yog hu ua trigonometric
Dab tsi yog cov reactants thiab cov khoom ntawm electron thauj saw hauv cellular respiration?
Lub ntsiab biochemical reactants ntawm ETC yog cov electron pub succinate thiab nicotinamide adenine dinucleotide hydrate (NADH). Cov no yog tsim los ntawm cov txheej txheem hu ua citric acid voj voog (CAC). Cov rog thiab suab thaj tau tawg mus rau hauv cov molecules yooj yim xws li pyruvate, uas tom qab ntawd pub rau hauv CAC
Vim li cas nws nyuaj rau pov tseg cov pov tseg nuclear?
Nuclear pov tseg yog ib qho nyuaj tshaj plaws ntawm cov pov tseg rau kev tswj hwm vim tias nws muaj kev phom sij heev. Vim nws cov xov tooj cua thiab cov khoom muaj kev phom sij heev, cov khib nyiab nuclear yuav tsum tau ua tib zoo khaws cia lossis rov ua dua
Cov neeg nqa khoom ntawm cov saw hlau thauj electron nyob qhov twg?
Nyob rau hauv eukaryotes, ib qho tseem ceeb electron thauj saw yog pom nyob rau hauv lub puab mitochondrial membrane qhov twg nws ua hauj lwm raws li qhov chaw ntawm oxidative phosphorylation los ntawm kev ua ntawm ATP synthase. Nws kuj pom muaj nyob rau hauv thylakoid membrane ntawm chloroplast hauv photosynthetic eukaryotes
