Answer 1

Right answer is (d) G-proteins

The explanation is: Arrestins are a small group of proteins that bind to the G-protein coupled receptors. To bind to these receptors, the arrestins compete with heterotrimeric G-proteins. In the process of desensitization, arrestin binding prevents further activation of the G-proteins.
