Question 4 Q . OH ATP OH POH ОН Fructose 6-phosphate Fructose 1.6-bisphosphate Figure 1. Reaction catalyzed by phosphofructokinase (PFK) during glycolysis Phosphofructokinase (PFK) is an enzyme that catalyzes the conversion of fructose 6- phosphate to fructose 1,6-bisphosphate during glycolysis, as represented in Figure 1. PFK can be allosterically inhibited by ATP at high concentrations. Which of the following is the benefit of regulating glycolysis by the concentration of ATP? Glycolysis proceeds when the intracellular concentration of ATP is low,...

please explain answer
Glycolysis. In the third step of glycolysis, the enzyme phosphofructokinase transfers a phosphate group from ATP to fructose-6-phophate to generate fructose- 1,6- bisphosphate. In contrast, in step 10, the enzyme pyruvate kinase transfers a phosphate group from phosphoenolpyruvate to ADP to generate ATP. Using what you know about the standard free energy change associated with phosphate bonds, (briefly) explain why we observe this difference.

A highly regulated reaction in glycolysis involves the addition
of a second phosphate to fructose-6-phosphate, which could be be
written as:
Fructose-6-phostphate + Pi à Fructose-1,6-bisphosphate + H2O
The ∆Go’ for this reaction is +16.8 kJ/mol
In a muscle cell at 37 oC, assume the concentration of
Fructose-6phosphate is 0.014 mM and the concentration of phosphate
is 1 mM.

Glycolysis. In the third step of glycolysis, the enzyme phosphofructokinase transfers a phosphate group from ATP to fructose-6-phophate to generate fructose- 1,6- bisphosphate. In contrast, in step 10, the enzyme pyruvate kinase transfers a phosphate group from phosphoenolpyruvate to ADP to generate ATP.
