Which of the following statements accurately describes the three stages of cell signaling as presented in the text?

  • A: Signal reception always occurs with receptor proteins located inside the cell.
  • B: Signal transduction involves the conversion of the signal into a form that can elicit a specific cellular response.
  • C: Relay molecules are typically involved in the signal reception stage.
  • D: The final outcome of cell signaling, such as the release of glucose from glycogen, is termed the cellular response.
  • E: Signal transduction is always a single-step process.

Explanation

The text clearly defines signal transduction as the conversion of the signal into a form for cellular response, and the cellular response as the final outcome like glucose release. It also states that reception can occur on the cell surface or inside, and transduction often involves multiple steps with relay molecules.
