Consider the steps in activation of a cellular response. I. Protein kinase A is activated. II. Ligand binds to G protein-coupled receptor. III. ATP is converted into cAMP. IV. The alpha subunit of the G protein activates adenylyl cyclase. V. GDP is replaced by GTP in the G protein. In what order do the steps for the activation of a cellular response take place
