According to Figure 39.3, what is the correct sequence of events in a general signal transduction pathway?

  • A: Transduction -> Reception -> Response
  • B: Reception -> Transduction -> Response
  • C: Response -> Reception -> Transduction
  • D: Reception -> Response -> Transduction

Explanation

The general model for signal transduction pathways, as depicted in Figure 39.3, involves three main stages: Reception the detection of a signal by a receptor , Transduction the relaying and amplification of the signal within the cell, often involving relay proteins and second messengers , and Response the activation of specific cellular activities .
