Glucose concentration (mM)
The Michaelis Menten constant (KM) of hexokinase IV is higher than 5 mM
The Michaelis Menten constant (KM) of hexokinase I and hexokinase IV is equal.
Around [glucose] = 5 mM, hexokinase I activity has the strongest dependence on [glucose].
If [glucose] > 5 mM, the activity of hexokinase I is independent of [glucose].
If [glucose] > 5 mM, the activity of hexokinase IV is independent of [glucose].
Around [glucose] = 5 mM, hexokinase IV activity has the strongest dependence on [glucose].
At [glucose] = 5 mM, the activity of hexokinase I and hexokinase IV is equal.
The maximum reaction rate (V) of hexokinase I and hexokinase IV is equal.
The Michaelis Menten constant (KM) of hexokinase I is higher than 5 mM.
Hexokinase IV activity is constant at [glucose] > 5 mM.
