Liver Liver protein activated after breakfast!

He has been reluctant to follow the diet prescribed by his physician, but as part of his recovery program, he has taken up running. Following an early morning run, he consumes a breakfast consisting of cereal, eggs, bacon, sausage, pancakes with maple syrup, doughnuts, and coffee with cream and sugar. Which of the following proteins will most likely be activated in his liver after breakfast?
A. Glycogen phosphorilase
B. PEP carboxykinase
C. Hydroximethylflutaryl-CoA reductase
D. Glycogen synthase
E. Carnitine acyltransferase
