The ability of an animal to respond
to its external and internal environment depends on
both intercellular and intracellular signaling pathways.
Proteins along with small molecules such as ions, sugars,
lipids and nucleotides form the basis of communication
in intracellular signal transduction.
In this topic, you'll look at intracellular signal
transduction and see how it enables a female mosquito
to find her blood meal.
