Glucagon binding to its liver receptor a. Cyclic AMP binding to regulatory subunits of protein kinase a. increases b. decreases 12. A drug that activates glycogen phosphorylase phosphatase a. increases b. decreases 13. The debranching enzyme. The branching enzyme.
Caffeine inhibits the phosphodiesterase enzyme that is involved with the second messenger mechanism.
Identify the correct statement concerning the effect that glucagon, binding to its cellular receptor, has on the liver. It causes a GTP-alpha subunit complex to dissociate from a G protein. It causes the inhibition of protein kinase. It causes a G protein to hydrolyze GTP, thus causing its subunits to associate. It causes a drop in cyclic AMP in the cell.
