Place the following events in the proper order. 1) Activation of one or more cellular signaling proteins. 2) Dissociation of Ga from the G protein complex. 3) Production of a second messenger, like cAMP. 4) Replacement of GDP by GTP on the Ga after interaction with an activated GPCR. 5) Conformational change in the Ga subunit causing a decreased affinity for the Gb g subunit. 6) Ga-subunit with its attached GTP activates an effector like adenylyl cyclase.

4) Replacement of GDP by GTP on the Ga after interaction with an activated GPCR.

5) Conformational change in the Ga subunit causing a decreased affinity for the Gb g subunit.

2) Dissociation of Ga from the G protein complex.  

6) Ga-subunit with its attached GTP activates an effector like adenylyl cyclase.

3) Production of a second messenger, like cAMP.    

1) Activation of one or more cellular signaling proteins.

Explanation:

It is a signaling cascade initiated by G proteins. These G proteins function as molecular switches capable of activating signaling pathways in the presence of guanosine triphosphate (GTP), which is hydrolyzed in order to produce energy

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).
