Question

The charge that a neuron at rest maintains is due to the presence of a high number of ________ charged ions inside the neuron's membrane.
A) actively
B) passively
C) negatively 
D) positively

Quizplus · Accepted Answer

The charge that a neuron at rest maintains is called the resting potential and it is due to the presence of a high concentration of negatively charged ions, such as chloride (Cl-) and proteins, inside the neuron's membrane. This creates an electrical gradient that attracts positively charged ions, such as sodium (Na+) and potassium (K+), but the membrane is selectively permeable, allowing only certain ions to pass through, which generates the resting potential.
