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

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

Glycolysis
Which of the following is not true of glycolysis?

The pathway does not require oxygen
The pathway oxidizes two moles of NADH to NAD+ for each mole of glucose that enters
