You are right, the phosphate group comes from inorganic phosphate. During glucose metabolism, glucose -6- phosphate is formed due to phosphate donated by ATP. Glucose-6-phosphate can be converted into ribulose-5-phosphate during certain reactions. Finally, ribulose-5-phosphate is converted to ribose-5-phosphate, used in nucleotide metabolism. As phosphate group of ATP, donated to glucose, comes from inorganic phosphate, it is possible to conclude that phosphate of nucleotide has the same origin.

Addition of Phosphate groups to molecules usually requires ATP as source of energy but in glycolysis a phosphate group is added to Glyceraldehyde-3-P without a ATP molecule. How?

Glyceraldehyde-3-P (GAP)  is also known as  triose phosphate. ATP molecule is not required when adding a phosphate group to Glyceraldehyde-3-P since the triosephosphate isomerase enzyme rapidly transforms the molecules so that...

In the case of glycolysis, glucose is the recipient of a phosphate group. What effect does the phosphate group have on glucose?

A phosphate group is transferred from ATPstart text, A, T, P, end text to glucose, making glucose-6-phosphate. Glucose-6-phosphate is more reactive than glucose, and the addition of the phosphate also...

Is H3PO4 a triprotic or diprotic acid, if it is a trprotic acid, then how do we explain its reaction with sodium hydroxide? i.e. H3PO4 + 2NaOH == Na2HPO4 + 2H2O.

H3PO4 is a trprotic acid,but the reactivity of cleavage ща proton determine the dissociation constant. For the third proton is much smaller than for the second and first H3PO4(s) +...

Ca5(PO4)3F + 5H2SO4 = 3H3PO4 + 5CaSO4 + HF if 24.5 g Ca(PO4)3F is mixed with 89.7 g H2SO4, how much H3PO4 will form? NEED IT TODAY

The quantity of Ca5(PO4)3F:(24.5 g) / (504.3 g/mol) = 0.0486 molThe quantity of H2SO4:(89.7 g) / (98.1 g/mol) = 0.9144 molThe ratio of these reactants must be 1:5, so H2SO4...
