Glycolysis Why does the glycolytic pathway continue in the direction of glucose catabolism? Glycolysis occurs in either 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 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 There are essentially three irreversible reactions that act as the driving force for the pathway The enzymes of glycolysis only function in one direction ANSWER DOWNLOAD EXAMIANS APP
