Question

Hexokinase has a Km of 0.1 mM for glucose, whereas glucokinase has a Km of 10 mM for glucose. What does that mean for their relative affinities for glucose? Select one: a. Glucokinase has a higher affinity. b. Km does not measure affinity. c. Hexokinase has a higher affinity. d. They are different enzymes and affinity cannot be compared between enzymes.

Given: Glucokinase (in liver) catalyzes the same reaction as hexokinase, but compared to hexokinase, glucokinase has a substantially higher Km for glucose. Which of the following statements is most reasonable? When glucose levels rise after a meal, the hexokinase reaction speeds up but the glucokinase reaction does not. When glucose levels rise after a meal, the glucokinase reaction speeds up but the hexokinase reaction does not. When ATP levels rise after a meal, the glucokinase reaction speeds up but the hexokinase reaction does not.

What is the significance of the fact that glucokinase is found in liver and β cells of the pancreas and that hexokinase is found in most other cells? A. The role of hexokinase is to provide glucose 6-phosphate for the synthesis of fatty acids B. At low glucose levels, very little is taken up by the liver, so glucose is spared for other tissues C. Glucokinase phosphorylates glucose when blood glucose levels are low D. Hexokinase is not inhibited by glucose 6-phosphate, allowing accumulation in muscle for storage as glycogen E. Hexokinase has a high KM, so it does not become saturated until blood glucose levels are extremely high

00:01 Hello everyone in this question they have given two enzymes the first enzyme is exokinase the first enzyme is exokinase and for that the value km they have given that is michaelis maintenance constant that is 0 .1 mm molar and also they have given another enzyme that is glucokinase enzyme and for that the michael is maintained constant value is 10 millimolar and they have asked that which one having higher the affinity toward the glucose...
