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.

where in your body is there an enzyme that does function at a high or low ph? what is the name of that enzyme and its function?
