Answer:

As their name implies, GPCRs interact with G proteins in the plasma membrane. When an external signaling molecule binds to a GPCR, it causes a conformational change in the GPCR. This change then triggers the interaction between the GPCR and a nearby G protein.

What happens to the membrane protein (gray) when it is activated by the signal molecules?

The membrane protein interacts with the nearby GPCR.

Answer:

The receptor protein that is embedded in the cellular membrane must accept the signal.

Step-by-step explanation:

When it receives the signal this protein will then go through a conformational change. This will change the shape and how it interacts with the molecules around it. Different receptor protein will act in different ways.
