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

Glycolysis Why does the glycolytic pathway continue in the direction of glucose catabolism? 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 The enzymes of glycolysis only function in one direction Glycolysis occurs in either direction ANSWER DOWNLOAD EXAMIANS APP
