In a scenario where the GDP to GTP exchange in the stimulatory G protein is inhibited, what would be the immediate consequence in the signaling pathway?

• A. The GPCR would undergo a conformational change without ligand binding.
• B. The alpha subunit would remain inactive and unable to dissociate from the beta gamma subunits.
• C. Protein kinase A would be activated without the need for cyclic AMP.
• D. Adenylate cyclase would be activated directly by the beta gamma subunits.

Answer: (B)
