Questions and Answers

What role do scaffolding proteins play in cell signaling?

  • They prevent signal transduction efficiency.
  • They group together different proteins involved in the same pathway to enhance efficiency. (correct)
  • They simplify the signaling pathways by separating different proteins.
  • They exclusively activate all relay proteins in the cell.
  • How do different cell types respond to the same signal?

  • They may respond differently due to the presence of different proteins or pathways. (correct)
  • Their response is always dependent on extracellular conditions.
  • They do not respond to the signal at all.
  • They respond in the exact same manner, regardless of cell type.
  • What is meant by 'pathway branching' in cell signaling?

  • It describes the process where a single signal leads to multiple signaling outcomes. (correct)
  • It indicates an increase in the number of signaling proteins present in the cell.
  • It suggests a slowing down of signal transduction within the cell.
  • It refers to the linear progression of a signal without any divergence.
  • What is a critical function of the proteins that allow cells to detect signals?
