Some bacteria have developed a resistance to antibiotics through random mutations. One such mutation allows bacteria to produce enzymes that inactivate the antibiotics when they enter the bacteria. Which statement describes how this mutation occurs?

The statement 'epinephrine binds to a cell-surface receptor and then it stimulates the production of cAMP' CORRECTLY describes the initial steps by which epinephrine stimulates glycogen breakdown (Option 1).

Epinephrine (also called adrenaline) is a hormone well known to stimulate glycogen breakdown.This hormone (epinephrine) binds to specific G-protein-coupled receptors localized in the surface of hepatocytes to drive glycogen breakdown. This binding in turn activates an enzyme called adenylyl cyclase to increase the formation of cyclic adenosine monophosphate (cAMP), which is a common second messenger that mediates diverse biological responses.

In conclusion, the statement 'epinephrine binds to a cell-surface receptor and then it stimulates the production of cAMP' CORRECTLY describes the initial steps by which epinephrine stimulates glycogen breakdown (Option 1).
