Answer 1

levels of cAMP

Step-by-step explanation:

protein kinase A enzyme is also called as A kinass or the cyclic AMP-dependent protein kinase. It is an enzyme that covalently links aor adds proteins with phosphate groups. The activity of this enzyme is regulated by varying levels of cyclic AMP within cells, because of this the enzyme is also called as the cyclic AMP-dependent protein kinase.
