The receptor may well Handle calcium inflow through the outer cell membrane, thereby altering the concentration of free of charge calcium ions throughout the cell, or it may well Handle the catalytic action of one or more membrane-sure enzymes. A single of such enzymes is adenylate cyclase, which catalyzes the conversion of adenosine triphosphate (ATP) inside the cell to cAMP, which consequently binds to and activates intracellular enzymes that catalyze the attachment of phosphate teams to other functional proteins; these might be associated with numerous types of intracellular processes, for instance muscle mass contraction, mobile division, and membrane permeability to ions.
