Metabotropic receptors
Alpha & beta receptors of adrenergic receptors are categorized as metabotropic or G-protein coupled receptors. Becase they act through the second messenger system of G-proteins. cAMP, IP3, DAG and Ca+2 are the importantt secondary messengers.
Alpha and beta receptors of adrenergic system act through sercondary messengers of GPCRS, They are metabtropic receptors.
G-protein coupled receptors are also known as heptahelical (seven transmembrane-spanning) receptors or metabotropicreceptors. They are connected to the intracellular system through G-protein molecules that activate secondary messengers. The three important secondary messengers are cAMP (cyclic adenosine monophosphate), IP3 (ionositol 1,4,5-triphosphate) act through calcium ions, and DAG (diacyl glycerol).

When neurotransmitters bind to metabotropic receptors, they bind to the _________ of the receptor, causing the receptor to change shape, which is the first step in an intracellular signaling cascade. One essential neurotransmitter, acetylcholine, can generally exert excitatory effects when binding to its ionotropic receptors but can have either excitatory or inhibitory effects when binding to _____________ receptors. When neurotransmitters like acetylcholine bind to _________ receptors they let ions (e.g. Na+, Cl-) into the neuron directly through that channel they...

There are two main types of adrenergic receptors: the alpha and beta adrenoceptors. Noradrenaline shows slight selectivitty for the alpha receptor, whereas isoprenaline shows selectivity for the beta adrenoceptor. Adrenaline shows no selectivity and binds equally well to both the alpha and beta forms of the adrenoceptors. Draw the chemical structures for noradrenaline, isoprenaline, and adrenaline. suggest an explanation for these differencse in selectivity relative to the binding site of each receptor.
