Adrenaline Glucagon Messenger Receptors Enzyme Called Adenylate Cyclase

Adrenaline and glucagon bind to receptors, activating adenylate cyclase which produces cAMP (a second messenger). cAMP then triggers protein kinase A, initiating reactions that break down glycogen into glucose.

This card explains the second messenger model for adrenaline and glucagon: they bind to receptors, activating adenylate cyclase, which converts ATP to cAMP (the second messenger), activating protein kinase A to break down glycogen into glucose.

Front Second Messenger model of adrenaline and glucagon
Back Receptors for adrenaline and glucagon have specific teritary structures which make them complementary to their respective hormones

Adrenaline and glucagon bind to receptors and activate an enzyme called adenylate cyclase

Activated adenylate cyclase converts ATP into chemcial signal known as "Second Messenger"

Second messenger known as Cyclic AMP (cAMP)
cAMP activates enzyme called protein kinase A which activates a chain of reactions that break down glycogen into glucose
