Question

Step 7 of Epinephrine Signal Transduction.

a) Activation of adenylate cyclase.
b) Binding of epinephrine to its receptor.
c) Conversion of ATP to cAMP.
d) Activation of protein kinase A.

Answer 1

The conversion of ATP to cAMP by adenylyl cyclase is a step in the epinephrine signal transduction pathway.

Step-by-step explanation:

The epinephrine signal transduction pathway involves several steps. One of these steps is the conversion of ATP to cAMP by the enzyme adenylyl cyclase. This occurs after the binding of epinephrine to its receptor and the activation of a G-protein, which then activates adenylyl cyclase. The resulting cAMP acts as a second messenger that mediates a cell-specific response.
