Which Sense is Based on Indirect, G Protein-Coupled Receptor Activation

Question

Which sense is based on indirect, G protein-coupled receptor activation?
A) Vertebrate touch
B) Insect hearing
C) Insect vision
D) Vertebrate hearing

Accepted Answer

Insect vision involves G protein-coupled receptors, specifically in the phototransduction pathway where light activates rhodopsin, a G protein-coupled receptor, leading to a cascade of intracellular events.
