Ib qho tshuaj tiv thaiv ntawm glycolysis tshem tawm 4 lub zog hluav taws xob siab, dhau mus rau tus neeg nqa hluav taws xob hu ua NAD+ . Txhua NAD+ lees txais ib khub ntawm lub zog hluav taws xob thiab dhau los ua NADH molecule. Lub NADH molecule tuav cov electrons kom txog thaum lawv tuaj yeem hloov mus rau lwm cov molecules.
Yuav ua li cas rau cov piam thaj thaum cov electrons raug tshem tawm?
Tshem tawm cov electrons los ntawm cov piam thaj ua rau glucose poob sib nrug ua ob lub molecules ntawm pyruvate. … Cov neeg nqa khoom siv hluav taws xob, thaum lawv tau tso tawm ntawm cov hluav taws xob mus rau cov saw hlau thauj hluav taws xob tsis pub rov qab mus rau cytoplasm thiab pab cov txheej txheem ntawm glycolysis.
Y Yuav ua li cas rau cov piam thaj thaum lub sijhawm glycolysis?
Thaum glycolysis, glucose kawg zom rau hauv pyruvate thiab lub zog; tag nrho ntawm 2 ATP yog muab los ntawm cov txheej txheem (Glucose + 2 NAD + + 2 ADP + 2 Pi 2 Pyruvate + 2 NADH + 2 H + + 2 ATP + 2 H2O). Cov pab pawg hydroxyl tso cai rau phosphorylation. Daim ntawv tshwj xeeb ntawm cov piam thaj siv hauv glycolysis yog qabzib 6-phosphate.
Yuav ua li cas cov electrons tshem tawm hauv glycolysis?
Molecular oxygen
Yuav ua li cas yog tias tsis muaj oxygen los ntes electrons?
Yog tias tsis muaj oxygen los txais cov khoom siv hluav taws xob (piv txwv li, vim tias ib tus neeg tsis ua pa oxygen txaus), cov saw hlau thauj hluav taws xob yuav tsum tsis ua haujlwm, thiab ATP yuav tsis raug tsim los ntawm chemiosmosis.
Pom zoo:
Thaum lub sijhawm ua pa ntawm tes uas ntawm cov hauv qab no tso tawm los ntawm cov khoom lag luam?
Thaum lub sijhawm ua pa aerobic cellular, qabzib reacts nrog oxygen, tsim ATP uas tuaj yeem siv los ntawm tes. carbon dioxide thiab dej yog tsim los ntawm cov khoom lag luam. Hauv kev ua pa ntawm tes, qabzib thiab oxygen hnov qab tsim ATP.
Thaum glycolysis uas coenzyme txais cov electrons los ntawm cov piam thaj?
Txais cov hluav taws xob hluav taws xob los ntawm txo cov coenzyme carrier molecules ( NADH thiab FADH 2 ). Dab tsi molecule tshem tawm electrons los ntawm qabzib thaum lub sij hawm glycolysis? Yuav kom glycolysis tshwm sim, uas yog txhawm rau txhawm rau faib cov piam thaj molecule rau hauv 2 lub molecules ntawm pyruvate, qee cov electrons yuav tsum tau muab tshem tawm ntawm cov piam thaj.
Lub sijhawm ua pa pa ua pa hloov cov piam thaj rau?
Nyob rau hauv cov ntsiab lus, poov xab yog ib leeg-celled fungus uas siv cellular respiration, uas converts qabzib thiab oxygen rau hauv carbon dioxide thiab ATP. Nco ntsoov tias cov piam thaj yog cov suab thaj yooj yim uas muab lub zog rau ntau lub neej.
Lub sijhawm glycolysis uas coa txais cov electrons los ntawm cov piam thaj?
Glycolysis, qhov twg cov piam thaj yooj yim tau tawg, tshwm sim hauv cytosol. Pyruvate, cov khoom lag luam los ntawm glycolysis, hloov mus rau acetyl CoA hauv mitochondria rau cov kauj ruam tom ntej. Dab tsi molecule tshem tawm electrons los ntawm qabzib thaum lub sij hawm glycolysis?
Dab tsi yog qhov ceev ntawm cov hlau raug tshem tawm los ntawm lub cuab yeej ntawm lub workpiece?
1. Kev nrawm . Kev txiav ceev (v) ntawm ib lub cuab yeej yog qhov ceev uas cov hlau raug tshem tawm los ntawm lub cuab yeej ntawm lub workpiece. Nyob rau hauv ib lub tshuab dhos, nws yog lub peripheral ceev ntawm kev ua hauj lwm yav dhau los cov cuab yeej txiav qhia nyob rau hauv meters ib feeb.
