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.
