Caffeine prolongs the life span of acetylcholine molecules in the motor junctions. Explain how this fact is related to caffeine’s tendency to cause jitters, such as hand tremors and other small involuntary contractions.
Explain how inhibition can be produced by (a) muscarinic ACh receptors in the heart; and (b) GABAreceptors in neurons of the CNS.
Correct the following false statement:
"Any cell that has the acetylcholine receptor will have the same response as any other cell that also has the acetylcholine receptor when exposed to acetylcholine".
Explain why this statement is false.
