The two types of signals used by the body to transmit messages. Introduction: A signal transduction pathway includes a group of proteins and polysaccharides that carry the signals generated by the binding of the signaling molecule. The signals carried, leads to conformational changes in the proteins that further trigger a cascade of reactions leading to a cellular response.
