Creatation from adenosine triphosphate is catalyzed? by [adenylic cyclase]?. Decomposition into [adenosite monophosphate]? is catalyzed by phosphodiestrase?.
cAMP controls many biological processes, one of more important of them is glycogen? decomposition into glucose. One of others is lipolysis?.
In Bacteria, cAMP is hormone of hunger?. It is crearted if level of glucose in cell is low and it activates production of enzymes that might possibly supply glucose.
[Adenylic cyclase]? is located at cell's membranes. It is activated by hormones glucagon? and adrenaline. These hormones can't go through cell membrane, so all they activity is mediated by cAMP.
Liver's [adenylic cyclase]? reacts more strongly to glucagon?, and muscle's [adenylic cyclase]? reacts more strongly to adrenaline.
