This increases the blood glucose level. (iv) Antagonistic Effect: The effect of hormones which act against each other are called antagonistic effects. Many body cells use more than one second messenger.

WebThe second messenger, cyclic AMP, is made by the enzyme adenylate cyclase. Adenylate cyclase is a two‐component enzyme system. It ultimately catalyzes the cyclase reaction, but only when it is associated with the hormone‐bound receptor and a regulatory protein called a stimulatory G‐protein (guanylate nucleotide binding protein), which activates adenylate … WebAs you pointed urself, second messenger's are the once's that are free to move inside and outside the cell, and G proteins are membrane anchored proteins. Basically, G protein gets activated as a appropriate ligand ( a neurotransmitter or a hormone) comes and stimulates its receptors i.e The G-Protein Coupled Receptors.
