Q1. Discuss the importance of the experiments performed by Buck and Axel identifying a family of G-protein coupled receptors.
Q2. Review the later studies at Johns Hopkins that advanced our understanding of olfaction. Briefly review the results and discuss how they increased our understanding of this important sensory system.
Q3. Compare and contrast one other system in which G-protein coupled receptors transmit signals across cell membranes. For example, these receptors play in integral role in vision, but the means of signal amplification are very different.
