Question

In a lab you are conducting tests with various chemicals and neurotransmitter receptors. you notice that exposed frog muscle cells depolarize when you add the chemical nicotine to the acetylcholine (ach) receptors. what does this tell us about the relationship between neurotransmitters and their receptors?

Answer 1

The scenario above tell us that the effects of a neurotransmitter is based on the properties of the receptor to which they bind more than the neurotransmitter. Some neurotransmitters bring about stimulation when the bind to receptors while others brings about inhibition. The effect of a neurotransmitter on a receptor depends on the properties of that receptor.
