Glycolysis A kinase is an enzyme that removes phosphate groups of substrates removes water from a double bond uses ATP to add a phosphate group to the substrate uses NADH to change the oxidation state of the substrate removes phosphate groups of substrates removes water from a double bond uses ATP to add a phosphate group to the substrate uses NADH to change the oxidation state of the substrate ANSWER DOWNLOAD EXAMIANS APP

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
