The beta adrenergic receptor is An integral membrane protein
     The beta adrenergic receptor is  An integral membrane protein with seven transmembrane spanning domains.  A soluble cytosolic protein that phosphorylates other proteins  An amphitropic protein that is regulated| by P13K phosphorylation  A heterotrimeric peripheral protein that binds to the membrane with electrostatic interactions 
  
  Solution
Ans- D- beta adrenergic receptor is an heterotrimeric protein (which contains 1,2, 3) binds to the membrane with electrostatic interactions meant for fight/flight response, increasing the lipolysisprocess.
