Which Step in Glucagon Signaling Occurs in the G_{s $\alpha$} protein?
1)A Hydrolysis Reaction Cleaves a Fatty Acid from the protein

Which step in glucagon signaling occurs in the G_{s $\alpha$} protein?
1) A hydrolysis reaction cleaves a fatty acid from the stored triacylglycerols to generate diacylglycerol and a fatty acid.
2) The regulatory protein G58 binds to adipose triglyceride lipase.
3) Perilipin is phosphorylated on the surface of lipid droplets.
4) Albumin transports the free fatty acid.
5) A GDP-GTP exchange stimulates cyclic AMP production by the enzyme adenylate cyclase.

A) 1
B) 2
C) 3
D) 5
