Hexokinase and glucokinase are both liver enzymes that phorphorylate and trap glucose within the cell. The Km of hexokinase for glucose is about 100 times lower than the Km of glucokinase. What makes sense?

A. glucokinase traps glucose from blood in liver cells at lower concentration than hexokinase, so that liver cells function under fasting conditions

B. glucokinase traps glucose from blood in liver cells at lower concentrations in order to ensure production of glycogen for storage

C.	hexokinase traps glucose from blood at a lower concentration in order to store glycogen

D. hexokinase traps glucose from blood at lower concentration for cellular energy needs, while glucokinase traps glucose from blood at higher concentrations for glycogen storage and other long term metabolic needs

PART A: In a liver cell at 37 ?C the concentrations of both phosphate and glucose are normally maintained at about 5 mM each. What would be the equilibrium concentration of glucose-6-phosphate, according to the above data? ANS: Equilibrium concentration = 1.2×10?7 M PART B: This very low concentration of the desired product would be unfavorable for glycolysis. In fact, the reaction is coupled to ATP hydrolysis to give the overall reaction ATP+glucose?glucose?6?phosphate+ADP+H+ What is ?G?? for the coupled reaction?...

In humans, the concentration of glucose in the blood is maintained at roughly 5 mM. Hexokinase (HK II) in muscle is a Michaelis-Menten enzyme and its KM for glucose is about 0.1 mM. The blood glucose and intracellular glucose concentrations rapidly equilibrate so that the cellular glucose concentration can be considered to be essentially the same as the blood glucose concentration. Also, prolonged high concentrations of glucose in the blood can be toxic. a) What do the KM and the...
