The voltage at a receptor site has just changed from -70 millivolts to -75 millivolts.What caused the change

A)  excitatory postsynaptic potential 
B)  influx of potassium ions 
C)  influx of sodium ions 
D)  inhibitory postsynaptic potential

Millivolts

A unit of electric potential or electromotive force equal to one thousandth of a volt.

Inhibitory Postsynaptic Potential

A kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential.

Potassium Ions

Charged particles of potassium that play crucial roles in physiological processes, including nerve transmission and muscle contraction.

  • Identify the significance and role of key ions, like sodium and potassium, in neural processes.

Final Answer :
D
Explanation :
An inhibitory postsynaptic potential (IPSP) would cause hyperpolarization and a decrease in voltage, such as changing from -70 mV to -75 mV.
