Chapter 50.4, Problem 2CC

Summary Introduction

To explain: How is the amplification of signals (increase in signal strength during signal transduction) is beneficial in olfaction.

Concept introduction: GPCRs (G protein coupled receptors) are the membrane receptors that are most diverse and largest membrane receptors in case of the eukaryotes. In all the animals, for the purpose of feeding behavior, the chemical senses are essential. Perceptions of smell (olfaction) depends upon the chemoreceptors.
