According to the provided diagram and text in Concept 11.1, which of the following accurately describes the general three-stage cell-signaling pathway?

  • A: Signal Transduction -> Reception -> Cellular Response
  • B: Cellular Response -> Reception -> Signal Transduction
  • C: Reception -> Signal Transduction -> Cellular Response
  • D: Signaling Molecule -> Receptor -> Activation of Cellular Response

Explanation

The three-stage cell-signaling pathway consists of: 1 Signal reception, where a signaling molecule binds to a receptor; 2 Signal transduction, where the signal is relayed through a series of relay molecules; and 3 Cellular response, leading to an activation of cellular activity.
