Final answer:
Both graded potentials and action potentials use sodium ions. Graded potentials can be depolarizing or hyperpolarizing and involve the movement of various ions, including sodium. Action potentials also rely on the participation of sodium ions for depolarization and propagation along the axon.
Step-by-step explanation:
Both graded potentials and action potentials use sodium ions. Graded potentials are temporary changes in the membrane voltage that can be depolarizing or hyperpolarizing. Depolarizing graded potentials are often the result of Na+ or Ca2+ ions entering the cell, while hyperpolarizing graded potentials can be caused by K+ leaving the cell or Cl- entering the cell.

Action potentials also rely on the participation of sodium ions for depolarization and propagation along the axon. Action potentials also involve the movement of Na+ ions, which play a crucial role in depolarization and the propagation of the action potential along the axon.
