Document Summary

The reason why you smoke tobacco leaves compared to mint leaves. Molecules that carry info from place to place throughout the body. Red material: squirted from one material to another cell (transfers info) Depending on the way it sticks depends on if it send msg or not shape change occurs gets transmitted all throughout the structure from outside. When messenger molecule sticks to receptor: receptor wraps around m molecule: of cell to inside. Alteration of shape: allows it to stick to another. Interaction permits a cascade of events to happen, ultimate result= biologic response. Agonist interaction: drug mimics receptor molecule: able to transmit messages in absence of the normal messenger, nicotine acts as an agonist for ach. Blocks normal signal shape in a not normal manner. Shape change is a bit different at high doses causes messenger to change. Not able to stick to receptor no signal sent. Drug occupies space but doesn(cid:495)t send signal.
