Solved in 3 steps
- Briefly describe the series of events that takesplace when cAMP acts as a second messenger.Heroin (diamorphine) is: O an opioid receptor antagonist. O a long-acting opioid agonist that produces dysphoria. O a drug that is metabolised in humans to morphine. a drug with high liability for physical dependence and low liability for psychological dependence. Question 4 Cocaine exerts sympathomimetic activity by: O acting directly as an agonist at alpha 1-adrenoceptors. inhibiting the re-uptake of noradrenaline at axon terminal sympathetic neurons. O inhibiting alpha 1-adrenoceptors. O inhibiting the breakdown of noradrenaline by monoamine oxidase.List examples of second messengers, and explain how they exerttheir effects.
