5 0

Answer:

The correct answer is  B. A small substance generated in response to receptor binding that activate or inactivate specific proteins.

The AMPC is involved in cell signal transduction pathways before external and / or internal stimuli, (example: adrenaline hormone), being able to activate the enzyme called protein kinase A (PKA), which phosphorylates its target and thus the signal is transmitted.
