Glycolysis During catabolism, only about 40% of the energy available from oxidizing glucose is used to synthesize ATP. Remaining 60% is stored as fat. is lost as heat is used to reduce NADP remains in the products of metabolism is stored as fat. is lost as heat is used to reduce NADP remains in the products of metabolism ANSWER DOWNLOAD EXAMIANS APP

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