Enzyme activators are molecules that bind to enzymes and increase their activity.
-
 
+
*An example of an enzyme activator working in this way is fructose 2,6-bisphosphate, which activates [[Phosphofructokinase (PFK)|phosphofructokinase 1]] and increases the rate of [[Glycolysis Enzymes|glycolysis]] in response to the hormone [[glucagon]].
-
== Function ==
+
*[[Hexokinase]]-I (HK-I) is an enzyme activator because it draws glucose into the [[Glycolysis Enzymes|glycolysis]] pathway. Its function is to phosphorylate glucose releasing glucose-6-phosphate (G6P) as the product. HK-I not only signals the activation of glucose into glycolysis but also maintains a low glucose concentration to facilitate glucose diffusion into the cell.

This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
