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

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
