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

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

Glycolysis
Which of the following is not true of glycolysis?

The pathway requires two moles of ATP to get started catabo-lizing each mole of glucose
The pathway does not require oxygen
ADP is phosphorylated to ATP via substrate level phosphorylation
