Answer: B im pretty sure.
Answer:
The cascade is responsible for amplification of the signal, so one activated receptor can have a significant response.
Explanation:
Signal transduction is any process occurring within cells that convert one type of signal/stimulus into another type. It is known as cell signalling in which transmission of molecular signals from a cell's exterior to its interior. Signals transmitted by cells must be transmitted effectively into cell to ensure an appropriate response. This step is initiated by cell surface receptors which triggers a biochemical chain os events inside the cell, creating a response.
Cascades are responsible to relay the signals hence these multisteps pathways can amplify a signal. Hence,The cascade is responsible for amplification the signal, so one activated receptor can have a significant response.
