Question

Combine your understanding of ATP conversion and PKA activation to explain how cyclic AMP acts as a secondary messenger in the signaling pathway.

Accepted Answer

Cyclic AMP activates protein kinase A, which then phosphorylates target proteins to elicit cellular responses.

Answer

Cyclic AMP directly binds to the GPCR to initiate the signaling pathway.

Answer

Cyclic AMP inhibits adenylate cyclase to prevent further ATP conversion.

Answer

Cyclic AMP is converted back to ATP to sustain the signaling cycle.
