Glycolysis Why does the glycolytic pathway continue in the direction of glucose catabolism? The enzymes of glycolysis only function in one direction Glycolysis occurs in either 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 The enzymes of glycolysis only function in one direction Glycolysis occurs in either 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 ANSWER DOWNLOAD EXAMIANS APP
Glycolysis A kinase is an enzyme that removes water from a double bond removes phosphate groups of substrates uses ATP to add a phosphate group to the substrate uses NADH to change the oxidation state of the substrate removes water from a double bond removes phosphate groups of substrates uses ATP to add a phosphate group to the substrate uses NADH to change the oxidation state of the substrate ANSWER DOWNLOAD EXAMIANS APP
