Homework Answers
Answer to the above question:
The following phosphate-containing compounds that are used in glycolysis are arranged in descending order according to their phosphoryl-transfer potential-
Phosphoenolpyruvate(PEP) (Highest phosphoryl-transfer potential)
1,3-bisphosphoglycerate
ATP
Glucose-6-phosphate (lowest phosphoryl-transfer potential)
Explanation: Phosphoryl-transfer potential is a means of comparing the tendency of organic molecules to transfer a phosphoryl group to an acceptor molecule.
PEP has high phosphoryl transfer potential because the phosphoryl group traps PEP into its unstable enol form. Once the phosphate group is transferred to ATP, the enol converts to a more stable ketone. PEP can transfer its phosphoryl group to ADP to form ATP;this is how ATP is generated directly during glycolysis.It is significant that ATP has a phosphoryl-transfer potential that is intermediate among the biologically important phosphorylated molecules. This intermediate position enables ATP to function efficiently as a carrier of phosphoryl groups ( accept phosphate from some, give phosphate to others) . Phosphoryl groups flow from high-energy donors, via the ATP-ADP system, to low-energy acceptors. So, PEP and 1,3-Bisphosphoglycerate can spontaneously transfer a phosphoryl group to ADP to make ATP, known as Substrate Level Phosphorylation .
