During the signal transduction process, the signal often triggers a signal transduction cascade. For example, an activated receptor activates hundreds of protein A. Each activated protein A activates hundreds of protein B and so on until a cellular response occurs. What purpose does this cascade serve? The cascade serves to amplify the signal, so one activated receptor can have a significant response. Having several intermediates allows for the cell to determine what signals it will sense. Having a cascade allows the cell to respond to different signals. The cascade makes signaling easier to shut off or terminate.

The correct answer is: The cascade serves to amplify the signal, so one activated receptor can have a significant response

The signal transduction process is represented by series of molecular events that end up with cellular response (change of behavior or characteristic).

Component of a signaling pathway (based on their role) are:

• Ligands or first messengers

• receptors or the signal transducers

• primary effectors

• second messengers

• secondary effectors ...

Signal transduction is part of almost all type of processes in the cell such as cell growth control, proliferation, metabolism etc.
