The value of K_m for the shown data for a hexokinase-catalyzed reaction is [Blank] with the unit of [Blank] The value of V_max for the same reaction is [Blank] with the unit of [Blank] Be sure to give the values with the correct number of significant figures. You might have to construct a kinetic plot. For units, choose one answer from (μM, 1/μM, μM/second, μM x second, mM, 1/mM, second, 1/second, mM/second, mM x second)

An enzyme catalyzed reaction has a Km of 3.76 mM and a Vmax of 6.72 nM/s. What is the reaction velocity in nM/s, when the substrate concentrations are: A. 0.500 mM B. 15.6 mM C. 252 mM D. Now assume you have added a competitive inhibitor that has a concentration of 15.6 µM with a KI of 7.30 µM to the enzyme in question 9. Calculate the velocity at the same substrate concentrations as above: E. 0.500 mM F. 15.6...

Imagine that you are observing an enzyme-catalyzed reaction in the laboratory. The reaction is progressing as expected. As you periodically add more enzyme, the reaction increases proportionally until suddenly it stops increasing. At this point, no matter how much more enzyme that you add, the reaction rate does not change. Assuming no other chemicals have been added or changed, explain why the reaction rate has leveled off.

A.) Let’s assume that the hexokinase reaction proceeds in the following manner as opposed to what we see in A) and B). Given this what is the new Keq? fructose-6-phosphate + ATP ↔ F16BP + ADP deltaG° = -14.2 kJ/mol B.) If we assume that the [ATP] is 10x greater than the [ADP] what is the new molar ratio of [F16BP]:[fructose-6-phosphate] at equilibrium? C.) If the cellular concentrations of fructose-6-phosphate and F16BP are 0.028mM and 0.014 mM respectively what does...
