Vedclass · Answer

(A) When adrenaline binds to its receptor on the surface of heart muscle cells,it activates the enzyme adenylate cyclase via a $G$-protein.This enzyme converts $ATP$ into cyclic $AMP$ $(cAMP)$.$cAMP$ acts as a second messenger that triggers a cascade of intracellular events,leading to increased calcium ion influx and enhanced muscle contraction.Therefore,$cAMP$ is the correct second messenger involved in this process.

In heart cells,which molecule acts as a second messenger and increases the contraction of muscle cells in response to adrenaline?
