If a hormone caused an increase in protein kinase activity, predict the type of hormone responsible and
the intracellular signaling mechanism of its action.
What will be an ideal response?
The hormone is most likely a peptide or protein--or other hydrophobic or non-lipid soluble molecule.
The receptor is a membrane bound receptor and a type of second messenger mechanism is involved.
The second messenger could either be cyclic AMP or G-proteins. In either case, the hormone-receptor
complex would either activate adenylyl cyclase or G-proteins. As a result, protein kinase would be
activated by the second messenger products.
