A G-protein receptor with GTP bound to it ________.
A) is in its active state
B) signals a protein to maintain its shape and conformation
C) will use cGMP as a second messenger
D) directly affects gene expression

Question

Quizplus · Accepted Answer

When GTP is bound to the G-protein receptor, it is in its active state and able to initiate downstream signaling pathways through second messengers such as cAMP or IP3. It does not directly affect gene expression or signal a protein to maintain its shape and conformation.
