Answer #1

option b is correct..

rapid effector pathways. effectors are group of proteins that interact with gpcrs which act as rapidly acting effector pathway through secondary messenger like calcium ion , adenylate cyclase.

option a is incorrect because it is not slow acting.

option c is incorrect because nmda glutamate receptors are ligand gated ion channel receptors not GPCR.

OPTION D is incorrect because it is not modulated effector pathwaybut secondary messenger pathway.

hope this helps. all the best ?

A patient arrives in the ED via EMS having a grand mal seizure. The ED physician instructs the RN to give 10 milligrams of Diazepam IV X1 dose STAT. The patient’s seizure breaks within 2 minutes of the Diazepam being administered. The mechanism by which this medication causes rapid resolution of seizure activity is via which receptor type (effector pathway/receptor subtype)? A. Slow effector pathways/G-protein coupled receptor B. Slow effector pathway/ion channel C. Rapid effector pathways/G-protein coupled receptor D. Rapid...

1. Receptor A and Receptor B are both G-protein coupled receptors (GPCRs), expressed in the same cell, but they control different biological responses. Receptor A and Receptor B are known to bind and respond to Hormone A and Hormone B, respectively. Treatment of the cells in the laboratory with Hormone A and B revealed that activation of Receptor A results in a dramatic increase in cyclic-AMP levels in the cell, while activation of Receptor B results in increased inositol triphosphate...
