Please help with these questions! thanks!

Several prostaglandin derivatives were synthesized in the lab and tested for their ability to sensitize a prostaglandin-specific G-protein coupled receptor and modulate cholesterol metabolism. According to the information below, which of the prostaglandin derivatives (PD) would form the most stable complex with the receptor? A. PD1, Kp = 1 nM B. PD2, Kp = 1 uM C. PD1, Km = 1 nM D. PD2, KM = 1 uM In the cAMP-dependent activation of pyruvate kinase, which of the following amino acids is phosphorylated? A. His B. Thr C. Tyr D. Ser E. Lys

Explanation / Answer

B.PD2,KD=1um most stable complex with the receptor

E.LYS amino acid that is phosphorylated
