24. The following is the Higgins-Selkov model for the third step of glycolysis, which may have a limit cycle attractor. F' = 0.07 - kFA2 A' = kFA2 - 0.12A (Here, F represents the concentration of fructose 6-phosphate, and A represents the concentration of ADP.) If the reaction rate constant is k = 0.31, can this system have a limit cycle attractor? (Hint: Equilibrium points!)
