Hexokinase

The enzyme hexokinase phosphorylates (adds a phosphate group to) glucose in the cell's cytoplasm. In the process, a phosphate group from ATP is transferred to glucose producing glucose 6-phosphate.

Chemical equation

$Glucose_{in} + ATP \rightleftharpoons Glc6P + ADP$

Rate equation

Random Bi-Bi Michaelis Menten is used

$v = \frac{\frac{V_{mf}}{K_{Glu}K_{ATP}}\Big( [Glu][ATP] - \frac{[G6P][ADP]}{K_{eq}} \Big)}{1 + \frac{[Glu]}{K_{Glu}} + \frac{[ATP]}{K_{ATP}} + \frac{[Glu][ATP]}{K_{Glu}K_{ATP}} + \frac{[G6P]}{K_{G6P}} + \frac{[ADP]}{K_{ADP}} +\frac{[G6P][ADP]}{K_{G6P}K_{ADP}} + \frac{[Glu][ADP]}{K_{Glu}K_{ADP}} +\frac{[G6P][ATP]}{K_{G6P}K_{ATP}} }$
