What does it mean to say that a signal is transduced?

#Section 3: Genetics, Cellular and Molecular Biology
  1. The signal enters the cell directly and binds to a receptor inside.

  2. The physical form of the signal changes as it passes from the cell membrane to the ultimate intracellular target.

  3. The signal is amplified, such that even one signal molecule evokes a large response.

  4. The signal triggers a sequence of phosphorylation events inside the cell.
