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 remains in the products of metabolism is used to reduce NADP is stored as fat. is lost as heat remains in the products of metabolism is used to reduce NADP ANSWER DOWNLOAD EXAMIANS APP
Glycolysis Phosphofructokinase, the major flux-controlling enzyme of glycolysis is allosterically inhibited and activated respectively by ATP and ADP AMP and Pi ATP and PEP Citrate and ATP ATP and ADP AMP and Pi ATP and PEP Citrate and ATP 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 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 The enzymes of glycolysis only function in one direction ANSWER DOWNLOAD EXAMIANS APP
