Which of the following is a possible function of a protein?
a. Long-term energy storage (There are better things that store energy such as Fats, Lipids, etc)
b. Insulating organisms (Eliminated)
c. Storing genetic information (Eliminated.. job of nucleic acids)
d. Sending signals across the organism (My answer)

They serve as enzymatic catalysts, are used as transport molecules (hemoglobin transports oxygen) and storage molecules (iron is stored in the liver as a complex with the protein ferritin); they are used in movement (proteins are the major component of muscles); they are needed for mechanical support (skin and bone contain collagen-a fibrous protein); and it goes on...
from this, which option you suggest ?

Don't proteins also send signals across the organism?
They are used for structure, transporting other substances, storage, signaling from one part of an organism to another, movement, and defense against foreign substances.
Proteins are used for structural support, movement, signaling from one part of an organism to another, transporting other substances, increasing the rate of chemical reactions, and defense against foreign substances.
