[Q]: Question: Hepatic glycolysis differs from muscle glycolysis in that: 
 Options:  <0> A low blood glucose concentration results in the inhibition of hepatic pyruvate kinase but not of muscle. <1> Hexative hexokinase has more affinity for glucose than muscle hexokinase. <2> The glycolytic enzymes in the liver are located in the cytoplasm, while in the muscle they are in cytoplasms and mitochondria. <3> Hepatic glycolysis is anaerobic, while muscle glycolysis is aerobic. <4> The final product of hepatic glycolysis is acetyl-CoA, while in muscle glycolysis that pyruvate.
