Glycolysis Why does the glycolytic pathway continue in the direction of glucose catabolism? The enzymes of glycolysis only function in one 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 Glycolysis occurs in either direction The enzymes of glycolysis only function in one 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 Glycolysis occurs in either direction ANSWER DOWNLOAD EXAMIANS APP
Glycolysis During catabolism, only about 40% of the energy available from oxidizing glucose is used to synthesize ATP. Remaining 60% is used to reduce NADP is stored as fat. remains in the products of metabolism is lost as heat is used to reduce NADP is stored as fat. remains in the products of metabolism is lost as heat ANSWER DOWNLOAD EXAMIANS APP
