Not all intercellular signals require transduction. Which one of the following signals may be processed without transduction?
A) a lipid-soluble signal
B) a signal that is weakly bound to a nucleotide
C) a signal that binds to a receptor in the cell membrane
D) a signal that binds to the extracellular matrix

Lipid-soluble signals can diffuse directly through the lipid bilayer of the cell membrane and interact with intracellular receptors without the need for a signal transduction pathway. This is because their solubility allows them to pass directly through the cell membrane to reach their target receptors inside the cell.
