Problem:
Question: When glucagon binds to receptors on mammalian liver cells, it activates Protein Kinase A. This kinase will phosphorylate regulatory enzymes and have which of the following impacts on metabolism?
a) activation of Phosphofructokinase 1 followed by activation of gluconeogenesis
b) activation of Phosphofructokinase 2 followed by activation of glycolysis
c) activation of Phosphofructokinase 1 followed by inhibition of glycolysis
d) inhibition of glycogen phosphorylase followed by inhibition of glycogenolysis
e) activation of glycogen phosphorylase and activation of glycogenolysis
