A researcher is studying the function of a peptide hormone in rabbits and humans. He notices that this hormone has a different effect in these two mammals, even though the hormone receptor has the same sequence (and structure) in both animals. What accounts for this difference in hormone function?

Question

Quizplus · Accepted Answer

The difference in hormone function between rabbits and humans, despite having the same receptor sequence, can be attributed to sequence differences in components of the associated signal transduction pathway. These components are crucial for transmitting the signal from the hormone-receptor interaction to the final response in the cell, and variations in these pathways can lead to different outcomes in different species.
