People with asthma generally will not be prescribed a beta-blocker drug because it can trigger an asthma attack. In this context, you can determine that blocked beta-adrenergic receptors in the tissue of the lungs cause the asthma attack as they allow:

ALBUTEROL QUESTION: 17. People with asthma who have trouble breathing often take an "inhaler" of a drug called Albuterol. Albuterol has been shown to bind to the same receptor as Epinephrine. Albuterol opens the airways and allows people to get more air into their lungs. 17a. (1pt) Is albuterol an AGONIST or an ANTAGONIST for the Epinephrine receptor? Agonist DO NOT COPY & PASTE TEXT FROM ONLINE SOURCES! USE YOUR OWN WORDS. I WILL CHECK FOR COPIED TEXT AND NOT GIVE FULL CREDIT. 17b. (2pts) In two sentences, link Epinephrine signal transduction to Albuterol's effect on breathing. ANSWER PROPANOLOL QUESTION: 18. Propranolol is an antagonist of receptors on the heart. Many actors, singers, and musicians will use this drug to slow their heart rate during a performance so that they don't feel as nervous. 18a. (1pt) Propanol is an antagonist drug. Is it an antagonist for the acetylcholine receptor OR an antagonist for the epinephrine receptor? Antagonist for the epinephrine receptor 18b. (2pts) In two sentences, link the signal transduction pathway to Propanolol's effect on heart rate. ANSWER
Sri K.
Drugs called beta-blockers do all of the following except: a) reduce high blood pressure. b) block signaling through adrenaline receptors c) reduce outward symptoms of anxiety. d) bind to the cytoplasmic side of a receptor protein. e) reduce the effects of adrenaline on the heart
