What are the molecules that control appetite? (hint: next sentence) How
do the orexins, leptin and ghrelin work together to control appetite? Which cells are responsible
for producing these molecules and what are the molecular pathways that are activated? Identify
the targets and how the signaling pathways are regulated. Which molecules oppose appetite and how do they suppress the craving for food? You may need to consider not only the signaling
pathways but the neural pathways as well.
This is the topic, these questions need to be addressed in the research paper.
