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