Glucose transporters are a wide group of membrane proteins that facilitate the transport of glucose over a plasma membrane. Glucose is a vital source of energy for all life.

Chemical equation
![Glucose_{out} \rightleftharpoons Glucose_{in}](/wiki/images/math/1/d/f/1df253d28400fe40f15c5a6f95ae74a8.png)
Rate equation
Mono-Substrate reversible Michaelis-Menten with Haldane substitution is used[1].
![v = \frac{V_{mf}\Big([Glucose_{out}] - \frac{[Glucose_{in}]}{K_{eq}}\Big)}{K_{Glucose_{out}}\Big(1 + \frac{[Glucose_{in}]}{K_{Glucose_{in}}}\Big) + [Glucose_{out}]}](/wiki/images/math/5/2/f/52f388bcf345df8a8dae68f7aa8cb456.png)
