Question 1 in the cyclic AMP second messenger system binding

Question 1. in the cyclic AMP second messenger system, binding of the first messenger to a surface receptor leads to activation of_________ which includes the conversion of intracellular_________ to cyclic AMP

a. phospilipase C, ADP

b. adenylyl cyclase, ADP

c, phospholipase C, ATP

d. adenylyl cyclase, ATP

e. protein kinase, ATP

question 2. ATP synthase

a. transport hydrogen ions from the matrix to the intermembrane space(outer compartment) of the mitochondria.
