Protein phosphorylation is commonly involved with all of the following except
a. activation of receptor tyrosine kinases.
b. activation of protein kinase molecules.
c. activation of g protein-coupled receptors.
d. regulation of transcription by signaling molecules.

Protein phosphorylation is not involved in activation of G protein coupled receptor.

Further Explanation:

Roles of Protein phosphorylation are :

G- protein coupled receptor is activated through the external signals in the forms of ligand.

In this, ligand binds to the active site and cause conformation changes in receptor and active G- protein.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.
