question 100

Multiple Choice

During the signal transduction process, the signal often triggers a signal transduction cascade. For example, an activated receptor activates hundreds of protein A.

• A)Having several intermediates allows for greater control of the response.
• B)The cascade serves to amplify the signal, so one activated receptor can have a significant response.
• C)Having a cascade allows the cell to respond to different signals.
• D)The cascade makes signaling easier to shut off or terminate.
