Place the events in the correct order to
describe the five basic steps in the pathway of a signal transduction system.
A. receptor binding
B. receptor activation
C. signal transduction
D. response
E. termination
The opening of an ion channel as a result of nicotine association is an example of
_________________.
________________ occurs when an influx of ions causes an action potential, which carries
the signal to the reward areas of the brain.
Nicotine interaction with the transmembrane protein that normally binds the neurotransmitter
acetylcholine is an example of _________________.
________________ occurs when the signal causes release of dopamine in the brain, which
causes relaxation and feelings of well-being.
Rapid elimination of nicotine from the body is an example of ____________.
