Question

A G-protein receptor with GTP bound to it _____. Group of answer choices signals a protein to maintain its shape and conformation directly affects gene expression will use cGMP as a second messenger is in its active state.

Answer 1

Answer: Is in its active state

Explanation: G protein receptor, which is located in the cell membrane, by which they bind substances outside the cell, that is, extracellular, and transmit signals from these extracellular substances to internal, that is, an intracellular molecule, called G protein.

The G protein is activated and deactivated depending on which bond it is in question, i.e whether G protein is GTP or GDP bound. When G protein is bound to GTP then it is active and when it is bound to GDP then it is inactive. These two states, active and inactive, are also called two functional formations depending on the function. Such binding to one of these two guanine sub units (GTP and GDP) is easily accomplished by the alpha sub unit contained in the G protein, i.e by the chemical quality of the alpha sub unit.
