Assignment Help:

A new drug named ANTAG-CaSR has been developed that is an antagonist at calcium-binding sites of CaSRs (Calcium-Sensing Receptors) in the plasma membranes of parathyroid gland cells. 

Healthy Person P receives regular doses of ANTAG-CaSR as part of a clinical trial.  When ANTAG-CaSR levels in the extracellular spaces surrounding parathyroid gland cells increase in Healthy Person P, this leads to

A. an increase in the levels of calcium in the blood plasma.
