Question

in a neuron, the opening of sodium (na⁺) gates leads to _________. depolarization of the plasma membrane hyperpolarization of the plasma membrane plasma membrane voltage returning to the resting membrane potential question 23 (1 point) listen an inhibitory post synaptic potential (ipsp) causes which of the following? repolarization of the plasma membrane depolarization of the plasma membrane hyperpolarization of the plasma membrane neutralization of the plasma membrane

Explanation:

1. When sodium ($Na^+$) gates open in a neuron, sodium ions rush into the cell. This makes the inside of the plasma - membrane more positive relative to the outside, which is depolarization.
2. An inhibitory post - synaptic potential (IPSP) occurs when inhibitory neurotransmitters bind to receptors on the postsynaptic neuron. This typically allows chloride ($Cl^-$) ions to enter the cell or potassium ($K^+$) ions to leave the cell, making the inside of the plasma - membrane more negative, which is hyperpolarization.

Answer:

1. depolarization of the plasma membrane
2. Hyperpolarization of the plasma membrane
