Answer:

The conformational change in the G protein coupled receptor.

Explanation:

GPCR or the G protein-coupled receptor is one of the largest group of receptors in the eukaryotes.

The GPCR are seven-transmembrane receptors which are attached to the G proteins. The binding of the stimulus signalling molecules to the GPCR causes a conformation change in the GPCR. This conformational change in the GPCR disrupts the interaction between the G proteins and GPCR.

The change in the conformation of the receptor causes the dissociation of the G proteins and which can interact with other molecules of the membrane.

Thus, the conformation changes in the GPCR are the correct answer.
