Your 14-year-old son suffers from asthma. The condition usually worsens in the early spring when the plants are pollinating. He carries a rescue inhaler to help him when he starts to have trouble breathing. The active ingredient in the inhaler is albuterol, which is a beta-2 agonist. Why would albuterol be a good choice as a rescue medication? What is its mechanism? A. A beta-2 agonist will trigger the release of acetylcholine and dilate the bronchioles. B. A beta-2 agonist will bind to beta-2 receptors and mimic the sympathetic nervous system actions on the bronchioles. C. A beta-2 agonist will bind to beta-2 receptors and block the sympathetic nervous system actions on the bronchioles. D. A beta-2 agonist stimulates the release of norepinephrine and epinephrine from the adrenal medulla.
Peanut and tree allergies are on the rise in modern, industrialized countries. Exposure to a protein in the nuts causes sensitive people to react with skin hives, reddened skin, breathing problems including the closing of the throat (anaphylaxis), and even heart attack. Much like a mosquito bite or other insect bite, this is all mostly due to the actions of one hormone in particular. 1) What hormone triggers this reaction? 2) Why does it cause swelling/closing of the throat/airways? 3) How does it change or impact the heart rate and/or blood pressure to life-threatening levels?
Many species have a third type of LDH subunit that is found predominantly in the testes. If this subunit, called C, were expressed in other tissues and could combine with the M and H subunits, how many LDH isozymes would be possible? What would their compositions be?
Vitamin K questionsa) What transformation of glutamate side chains is Vitamin K (as its reduced form, VitaminKH2) involved in, and what is the relevance of this reaction to blood clotting?b) How does the blood thinner Coumadin (warfarin) prevent clotting?c) How can the dietary intake of large amounts of green vegetables, such as broccoli or kaleinterfere with the action of Coumadin?
How is methionine metabolism related to the synthesis of phosphatidylcholine?

2 of 16 Compound Binds to Elicits biological receptor response A Yes Yes B Yes No C No No Refer to the table above. Compound X is the natural ligand that binds to a receptor and stimulates a signal transduction pathway associated with the receptor. Based on the information given in the table, what are the roles of compounds A, B, and C? O A is an antagonist, B is an agonist, and C is a ligand. A is an agonist, B is an antagonist, and C has no role. A is a ligand, B has no role, and C is an antagonist. A is an agonist, B is an antagonist, and C is an agonist. A has no role, B is an agonist, and C is an antagonist.
