Ib nrab ntawm glycolysis yog hu ua lub zog them nyiaj theem. Hauv theem no, lub xovtooj tau txais ob ATP thiab ob NADH compounds. Thaum kawg ntawm theem no, cov piam thaj tau dhau los ua ib feem oxidized los ua pyruvate.
Yuav ua li cas hauv lub zog them nyiaj ntawm glycolysis?
Nqe them nyiaj theem. Hauv series ntawm cov kauj ruam uas tsim ib NADH thiab ob ATP, glyceraldehyde-3-phosphate molecule hloov mus rau hauv pyruvate molecule. Qhov no tshwm sim ob zaug rau txhua molecule ntawm qabzib txij li cov piam thaj tau muab faib ua ob peb-carbon molecules, ob qho tib si yuav dhau los ntawm cov kauj ruam kawg ntawm txoj kev.
Dab tsi yog lub zog yielding theem ntawm glycolysis?
Lub zog them nyiaj theem ntawm glycolysis muaj tsib kauj ruam ntxiv thiab ua rau muaj plaub ATP, ob NADH + H +, thiab ob lub pyruvate molecules. Substrate theem phosphorylation yog cov txheej txheem uas ATP yog tsim los ntawm kev hloov ntawm ib pab pawg phosphate los ntawm substrate molecule nyob rau hauv ib tug metabolic txoj kev.
Dab tsi yog thawj kauj ruam hauv theem them nyiaj ntawm glycolysis?
thawj kauj ruam hauv glycolysis yog hloov D-glucose rau hauv qabzib-6-phosphate. Lub enzyme uas catalyzes cov tshuaj tiv thaiv no yog hexokinase. Qhov thib ob cov tshuaj tiv thaiv ntawm glycolysis yog kev hloov pauv ntawm qabzib 6-phosphate (G6P) rau hauv fructose 6-phosphate (F6P) los ntawm qabzib phosphate isomerase (Phosphoglucose Isomerase).
Yuav ua li cas hauv lub zog them nyiajtheem thiab cov txiaj ntsig ntawm ATP yog dab tsi?
Kev nqis peev yog them rov qab nrog cov paj laum thaum lub sijhawm them nyiaj lub zog, thaum ATP yog tsim los ntawm substrate-theem phosphorylation thiab NAD + raug txo rau NADH los ntawm kev tso tawm ntawm electrons thaum lub sij hawm oxidation ntawm qabzib. Lub zog tawm los ntawm glycolysis, ib cov piam thaj molecule, yog ob ATP ntxiv rau ob NADH.
Pom zoo:
Lub sijhawm kuv lub sijhawm dawb lossis thaum kuv lub sijhawm dawb?
yog li, qhov no txhais tau tias "thaum kuv lub sijhawm dawb" tsis siv ntauthiab koj muab "hauv kuv lub sijhawm dawb" ntau dua nyob rau qhov kawg ntawm kab lus. Piv txwv li: Kuv tau taug kev tus dev thaum kuv lub sijhawm dawb.
Lub sijhawm nyob qhov twg ntawm lub sijhawm teem sijhawm?
kab kab rov tav ntawm lub rooj ntu ntu yog hu ua ntu ntu. Lub sijhawm nyob rau ntawm lub sijhawm nyob qhov twg? Ib lub sijhawm yog kab kab rov tav ntawm lub rooj ntu ntu. Muaj xya lub sij hawm nyob rau hauv lub sij hawm ntawm lub sij hawm, nrog txhua tus pib ntawm sab laug.
Lub sijhawm them nyiaj ntawm glycolysis?
Ib nrab ntawm glycolysis yog lub npe hu ua theem them nyiaj, tus cwj pwm los ntawm qhov nce ntawm lub zog nplua nuj molecules ATP thiab NADH. Txij li cov piam thaj ua rau ob lub suab thaj triose nyob rau theem npaj, txhua qhov tshuaj tiv thaiv hauv theem them nyiaj tshwm sim ob zaug ntawm cov piam thaj molecule.
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?
Lub sijhawm glycolysis electrons tshem tawm ntawm cov piam thaj raug xa mus?
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.
