Unformatted text preview: 20. (1 pt for each codon) 27/64 GGG Gly 9/64 GGU Gly 9/64 GUG Val 3/64 GUU Val 9/64 UGG Trp 3/64 UGU Cys 3/64 UUG Leu 1/64 UUU Phe 21. It activates protein kinase A which phosphorylates phosphorylase kinase and glycogen synthase (2 pts). Phosphorylase kinase in turn phosphorylates phosphorylase making it more active (1 pt). The phosphorylated form of glycogen synthase is less active (1 pt). 22. (1 pt) Binds to CAP; (1 pt) CAP-cAMP facilitates binding of RNA polymerase to promoter. 23. (2 pts) NH3 + KG interact to give a labeled amino group of Glu; enzyme = glutamate dehydrogenase; (2 pts) Then the following aminotransferase reaction gives labeled Ala: Glu + pyruvate = Ala + KG 24. (3 pts) Val + Enz-Pyr-CHO = Enz-Pyr-CH 2 NH 2 + -KIV (3 pts) Enz-Pyr-CH 2 NH 2 + KG = Enz-Pyr-CHO + Glu 25. Terminal3-carbon fragment is prop CoA (1 pt) methymalonyl CoA succinyl CoA (1 pt) OAA (1pt) Glucose in gluconeogenesis....
