WebIn the second step of glycolysis, an isomerase converts glucose-6-phosphate into one of its isomers, fructose-6-phosphate. An enzyme that catalyzes the conversion of a molecule into one of its isomers is an isomerase. (This change from phosphoglucose to phosphofructose allows the eventual split of the sugar into two three-carbon molecules). Step 3. Web13 hours ago · GLUT1 is one of the key molecules responsible for glucose transport and initiating glucose uptake in cells, where it is also involved in the regulation of aerobic glycolysis [39., 40., 41.In CD4 + T cells, decreased expression of GLUT1 decreases the glycolysis level, thus inhibiting their activation [42, 43].TEPP-46 is an allosteric activator …
