The correct answer is option 4 i.e. Sodium and potassium pumps.

  • The sodium potassium pump was discovered in 1957 by the Danish scientist Jens Christian Skou.
  • It's discovery marked an important step forward in the understanding of how ions get into and out of cells, and it has particular significance for excitable cells such as nerve cells, which depend on the pump to respond to stimuli and transport impulses.
