Glycolysis
Why does the glycolytic pathway continue in the direction of glucose catabolism?

High levels of ATP keep the pathway going in a forward direction
The enzymes of glycolysis only function in one direction
There are essentially three irreversible reactions that act as the driving force for the pathway
Glycolysis occurs in either direction
