Phosphoglyceraldehyde ua haujlwm cov khoom pib rau kev sib txuas ntawm cov piam thaj thiab fructose Glucose thiab fructose ua rau disaccharide sucrose, uas mus rau hauv kev daws rau lwm qhov chaw ntawm cov nroj tsuag (xws li, txiv hmab txiv ntoo., roots). Glucose kuj yog monomer siv nyob rau hauv synthesis ntawm polysaccharides starch thiab cellulose.
G3P siv tau dab tsi?
G3P feem ntau suav tias yog qhov kawg - cov khoom ntawm photosynthesisthiab nws tuaj yeem siv los ua cov khoom noj tam sim ntawd, ua ke thiab rov ua dua los ua cov suab thaj monosaccharide, xws li qabzib, uas. tuaj yeem thauj mus rau lwm lub hlwb, lossis ntim rau kev cia li insoluble polysaccharides xws li starch.
Kev ua haujlwm ntawm glyceraldehyde 3-phosphate dehydrogenase yog dab tsi?
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) yog ib qho kev txuag enzyme hauv txoj hauv kev glycolytic. GAPDH catalyzes kev hloov pauv ntawm glyceraldehyde 3-phosphate rau glycerate-1, 3-biphosphate, txheej txheem nrog los ntawm kev tsim cov NADH.
Glyceraldehyde phosphate pom nyob qhov twg?
In glycolysis, glyceraldehyde phosphate yog tsim thaum lub sijhawm ntxov dhau los ntawm kev tawg ntawm fructose-1, 6-bisphosphate los ntawm kev ua ntawm enzyme aldolase. Thaum lub sijhawm no, ATP yog siv los tsim glyceraldehyde phosphate thiab dihydroxyacetone phosphate.
Lub hom phiaj ntawm phosphorylation ntawm glyceraldehyde 3-phosphate yog dab tsi?
txheej txheem tso cai ATP synthesis los ntawm phosphorylation ntawm qib substratethiab yog qhov tseem ceeb los tsim kom muaj kev faib tawm ntawm triose-P [Ga3P thiab dihydroxyacetone-phosphate (DHAP)] ntawm cov cell sib txawv. compartments thiab metabolic pathways (Plaxton, 1996; Givan, 1999).
