Suppose that each β-adrenergic receptor bound to epinephrine converts 100 molecules of g α s into its gtp-bound form and that each molecule of activated adenylate cyclase produces 1000 molecules of camp per second. with the assumption of a full response, how many molecules of camp will be produced in 1 s after the formation of a single complex between epinephrine and the β-adrenergic receptor?

1x10^5 molecules of cAMP

Explanation:

The beta_adrenergic receptor can convert 100 molecules of adenylate cyclase into its GTP bounded form per molecule of epinepfrine.

Also, each molecule of activated adenylate cyclase (the GTP bound form) can produce 1000 molecules of cAMP per seconds.

Assuming full response means that all molecules of activated adenylate cyclase will produce que maximum cAMP response.

So, we have 100  activated adenylate cyclase molecules, each one producing 1000 molecules of cAMP.

That means we have 1x10^5 (100000) molecules of cAMP will be produced one second  (1 s) after the formation of the complex epinephrine-beta_adrenergic receptor

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
