Free-Response Question

Homeostatic maintenance of optimal blood glucose levels has been intensively studied in vertebrate organisms.

a)Pancreatic hormones regulate blood glucose levels. Identify TWO pancreatic hormones and describe the effect of each hormone on blood glucose levels.

b)For ONE of the hormones you identified in a), identify ONE target cell and discuss the mechanism by which the hormone can alter activity in that target cell. Include in your discussion a description of reception, cellular transduction, and response.

c)Compare the cell-signaling mechanisms of steroid hormones and protein hormones.
