First reaction of glycolysis
WebThe first reaction in Glycolysis is the phosphorylation of Glucose: Pi + Glucose → Glucose 6-Phosphate + water This is a thermodynamically unfavorable process with a ∆G0’ = +13.8 kJ/mol. In a liver cell at 370C the concentrations of both phosphate and glucose are normally maintained at about 0.005 M each. WebThe first series of reactions occurs with the first glyceraldehyde molecule from the orginal split. Then the second series of reactions occurs after the isomerization of the dihydroxyacetone into the glyceraldehyde. This …
