Place in the right order the sequence of biochemical events between the release of epinephrine by the adrenal glands and the breakdown of glycogen in the liver. (1) Epinephrine is released by the adrenal glands. ( ) Activated beta-adrenergic receptors cause GTP for GDP exchange in the alpha subunits of Gs G proteins ( ) The activated catalytic subunits of PKA phosphorylate the inactive phosphorylase kinase b, activating it. ( ) Epinephrine travels in the bloodstream ( ) Two cAMP...

Suppose that each β–adrenergicβ–adrenergic receptor bound to epinephrine converts 100100 molecules of the GαGα subunit to the GTP-bound form, Gαs.Gαs. If each molecule of activated adenylate cyclase produces 1000 molecules of cAMP per second, how many molecules of cAMP are produced in 10 seconds10 seconds after the formation of a single complex between epinephrine and the β–adrenergicβ–adrenergic receptor? Assume the pathway is fully responsive. Molecules of cAMP = ??

1. You are interested in how
cyclic-AMP-dependent protein kinase A (PKA) functions to affect
learning and memory, and you decide to study its function in the
brain. It is known that, in the cells you are studying, PKA works
via a signal transduction pathway like the one depicted in Figure
16-15. Furthermore, it is also known that activated PKA
phosphorylates the transcriptional regulator called Nerd that then
activates transcription of the gene Brainy. Which, if any
of the situations described...
