Detailed explanation-1: -Signal transduction usually involves multiple steps, called a signal cascade. Multi-step pathways (signaling cascades) can amplify a signal; even just a few molecules can cause a large cell response. Advantage: multi-step pathways can provide for more ways to coordinate and regulate the response.
Detailed explanation-2: -Multistep pathways allows a small number of extracellular signaling molecules to be amplified to produce a large cellular response and also provide opportunity for regulation and coordination.
Detailed explanation-3: -One benefit of multiple steps is the possibility of greatly amplifying a signal. If some of the molecules in a pathway transmit the signal to numerous molecules at the next step in the series, the result can be a large number of activated molecules at the end of the pathway.
Detailed explanation-4: -Signal transduction pathways play a crucial role in controlling the molecular processes that underlie living things, including metabolism, immunological responses, cell development, differentiation, and proliferation, as well as various forms of cell communication.
