What's the chemical structure of 3 groups hormones
1. contain peptides and proteins therefore water soluble, 2. derived from cholesterol therefore lipid soluble. 3. based on AA tyrosine; catecholamines and thyroid hormone
how do hormones work
bind to receptor, receptor sends biochemical response into the cell

Is first messenger hormone faster or slower than second messenger
slower
What is the most common second messenger for hormones
cyclic AMP
Which enzyme inactivates cAMP to cancel out that message
phosphodiesterase
