What is the correct order of the strength of chemical bonds that may occur between a drug and a receptor, from strongest to weakest?

Suxamethonium is a drug that activates a type of ion channel permeable to sodium in neurons. What effect will this drug most likely have on neurons?

GABA prevents neurotransmitter release when it interacts with GABA-B receptors, by decreasing the activity of protein kinase What other second messenger activity is also most likely decreased when GABA-B receptors are activated?

β-adrenergic receptor activity can be altered when a phosphate group is added to certain amino acids located on the receptor. What cell-surface receptor would most likely mediate this process?

A new drug decreases the activity of selectins. What is the most likely purpose of this drug?

A drug company is developing an anticancer drug that works by inhibiting the activity of a nuclear receptor. What physicochemical property is most important to ensure the drug is able to reach the receptor target?

Drug A causes drug B to be metabolized faster, thus reducing drug A's overall effectiveness. What is this an example of?

What does the Kd of a drug measure?

Why can’t a partial agonist produce the maximum tissue response. even if it occupies the same number of receptors as a full agonist?

Three experimental drugs that interact with the cannabinoid type I receptor (CB1) were evaluated for their effect on the gastrointestinal system. The CB1 receptor, when activated, has an inhibitory effect on Gl activity. The first drug, Drug A, had no overall effect on Gl function. The second drug, Drug B, caused an overall increase in peristalsis and gastric acid secretion. The third drug, Drug C, caused an overall decrease in peristalsis and gastric acid secretion. Binding studies show that all three drugs bind to the active site on the CBI receptor. What type of drug is Drug B?

The concentration response curve for Drug A shifted to the left in the presence Of Drug B. The concentration of Drug A required to reach the maximum response was altered. What type of drug is Drug B?

Studies suggest that approximately 90% of beta-adrenoreceptors are spare receptors. What evidence would that this is true?
