The active form of glycogen phosphorylase is phosphorylated, while the dephosphorylation of which active form occurs? Glycogen synthase Glycogen semisynthase Glycogen dehydrogenase Glycogen hydrolase TRUE ANSWER : ? YOUR ANSWER : ?
Phosphofructokinase, the major flux-controlling enzyme of glycolysis is allosterically inhibited and activated respectively by ATP and PEP AMP and Pi ATP and ADP Citrate and ATP TRUE ANSWER : ? YOUR ANSWER : ?
During catabolism, only about 40% of the energy available from oxidizing glucose is used to synthesize ATP. Remaining 60% remains in the products of metabolism is used to reduce NADP is lost as heat is stored as fat. TRUE ANSWER : ? YOUR ANSWER : ?
Why does the glycolytic pathway continue in the direction of glucose catabolism? 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 TRUE ANSWER : ? YOUR ANSWER : ?
