According to the text, what are the primary advantages of a multistep signal transduction pathway? Select all that apply

  • 1: Signal amplification, where a small number of signaling molecules can produce a large cellular response.
  • 2: Provides more opportunities for coordination and control of the cellular response.
  • 3: Enables faster signal transmission compared to direct signaling.
  • 4: Directly regulates gene expression without the need for relay molecules.

Explanation

The text explicitly states two benefits of multistep pathways: 'One benefit of using multiple steps is that a signal caused by a small number of signaling molecules can be greatly amplified.' and 'A second benefit of using multistep pathways is that they provide more opportunities for coordination and control than do simpler systems.'
