State whether the following is true or false.
Signal amplification means a few hormone molecules can produce a large cellular response.

  • A.True only at large scales
  • B.False only at small scales
  • C.True
  • D.False

Answer: C

Each stage of the cascade multiplies the number of active molecules, so the effect grows geometrically. This is why hormones are effective at concentrations far below those of ordinary metabolites. Nanomolar concentrations suffice where metabolites need millimolar.
