The epinephrine signaling pathway plays a role in regulating glucose homeostasis in muscle cells. The signaling pathway is activated by the binding of epinephrine to the beta-2 adrenergic receptor. A simplified model of the epinephrine signaling pathway is represented in Figure 1.
Cyclic AMP phosphodiesterase is an enzyme that catalyzes the conversion of cyclic AMP to a different molecule. Which of the following best predicts the effect of inhibiting cyclic AMP phosphodiesterase in a muscle cell stimulated by epinephrine?

Respuesta :

When cyclic AMP phosphodiesterase is inhibited in a muscle that is stimulated by epinephrine,there will be a crucial effect of making the phosphorylase kinase to remain active,this active state of the phosphorylase kinase is because the associated protein kinase A will not be deactivated any longer.

Epinephrine signaling pathway has varying steps,but the preceding step occurs when the associating hormone binds to the receptor of the epinephrine in the cell surface,the receptor then changes shape when the hormone triggers it,this makes the receptor to move to it's active form. GDP( guanosine diphosphate) is released after the G protein ( guanine nucleotide-binding proteins) binds to the receptor that is activated,the G protein then takes up a molecule of GTP (guanosine triphosphate) .

The Epinephrine signaling pathway is a series of steps in which a hormone binds to the epinephrine receptor present on the surface of the cell.

The enzyme cyclic AMP phosphodiesterase when inhibited in a muscle cell, which is stimulated by epinephrine, then there will be vital steps involved in the making of phosphorylase kinase to remain active.

The active state of the phosphorylase kinase is because the associated protein kinase A will not be deactivated.

Epinephrine signaling pathway consists of several steps, in which a hormone will bind to the receptor of epinephrine.

The shape of the receptor changes when a hormone binds and triggers the receptor to move in its active form.

Thus, the G protein from the guanine nucleotide-binding proteins is released and binds to the activated receptor, utilizing a molecule of GTP.
