HUMAN GROWTH HORMONE
1. Describe the ligand and any external receptors that bind tothe ligand. If signaling can occur without an external ligand,explain how this can occur.
2. Describe how the signal is translocated from the exterior ofthe cell to the interior of the cell. Be sure to describe thespecific activity of the receptor in initiating the intracellularsignal.
3. Describe the propagation of the signal within the cell fromthe membrane receptor to the point of cellular response. Providethe details for at least one specific protein interaction thateither results in the activation or inactivation of a subsequentprotein or signaling molecule to propagate the signal.
4. What is a specific cellular response to the signal.Something will change- what is it?
