Question
1. Phosphofructokinase is allosterically regulated. Draw and label the following and briefly describe what the plots indicate in terms of the properties of the enzyme: a. The shape of a Michaelis-Menton plot of velocity vs. fructose-6-P concentration for phosphofructokinase. b. Add to the plot a curve that would illustrate the effect of relatively high concentrations of ATP. c. High concentrations of fructose 2,6-bisphosphate decrease the affinity of the enzyme for ATP and thus can overcome the allosteric effects of ATP on the enzyme. Add to the plot a curve that would illustrate the effect of high levels of fructose 2,3-bisphosphate in the presence of ATP.
Explanation / Answer
In this Michaelis-menton plot of velocity equation, it mainly accelerates a typical enezyme in the reaction of kinetic way.
Here functios of susbtrate concentration afre ploted by one of the enzyme - catalyzed. Mainly the hyperbolic shape was given by the curve that was drawn.
The reaction velocity is mainly measured by the concentration values of the various several substrates.When the plot is with frctose is sigmodial in profile.Generally the PFK activity is inhibited in the ATP and moreover in ADP,AMP,and the cyclic AMP citrate activation occurs.
