Glycolysis During catabolism, only about 40% of the energy available from oxidizing glucose is used to synthesize ATP. Remaining 60% is lost as heat 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 ANSWER DOWNLOAD EXAMIANS APP
