Cell Signaling

It allows cells to perform various cellular activities, coordinate, and interact with other cells. All cells of an organism receive signals from their environments and respond accordingly. Even the unicellular eukaryotes receive signals secreted by other cells and respond. In the case of yeast, mating takes place by signaling between the yeast cells. Communication by cell signaling in a multicellular organism has become a vast and important part of various fields of biology.

Question

All cells of a multicellular organism may not respond in the same way
to a particular ligand (signaling molecule) that binds to a cell surface
receptor. The difference in response may be due to
a. the type of receptor for the ligand that the cell expresses.
b the affinity of the ligand for the receptor in a given cell type.
c. the type of signal transduction pathways that the cell expresses.
d. the type of target proteins that the cell expresses.
e. all of the above.
