Final answer:The opening of sodium gates in a neuron typically leads to thedepolarization of the plasma membrane.Explanation:In a neuron, the opening of sodium gates typically leads to thedepolarizationof theplasma membrane. This process begins when a channel opens for the sodium ions (Na*) in the membrane. Because the concentration of Na* is higher outside the cell than inside, these ions rush into the cell driven by the concentration gradient.Sodium, being a positively charged ion, changes the relative voltage inside the cell, causing it to become less negative; a process called depolarization. This means that the membrane potential moves toward zero, away from its resting potential at -70 mV. So, the opening of sodium gates in a neuron typically leads to the depolarization of the membrane, a crucial step in the firing of a neuron or creation of an action potential.Learn more about Depolarization here:brainly.com/question/31795021#SPJ11...
