potassium
The answer of potassium is dead wrong.
Sodium is the electrolyte that flows into the cell to initiate depolarization. Potassium flows into the cell during repolarization.

Is depolarization in the heart passed cell to cell in the same way they are the neuromuscular junction?
false
What ion flows into a nerve cell when an axon's membrane depolarizes?
During the depolarization phase, sodium ions enter the cell through the open ion-channels (Na+ influx).
How does the sodium potassium pump help with your homeostasis?
When a nerve cell (neuron) or muscle cell react, they do so by a process called depolarization. Before depolarization, the inside of the cell is slightly negative and the outside is slightly positive. During depolarization, sodium ions rush into the cell while potassium channels leak out. This reverses the original polarization and now the cell is said to be depolarized. The sodium/potassium pump helps reverse this back to its original polarized state so the cell can react again.
What does it mean when a cell is depolarized?
Depolarization refers to the reversal of charges of neuron cell membrane, it occurs by moving in of 'Na' ions .
Which pump is responsible for muscle contraction through depolarization of muscle cell membrane?
Ca2+
Is depolarization in the heart passed cell to cell in the same way they are the neuromuscular junction?
false
What ion flows into a nerve cell when an axon's membrane depolarizes?
During the depolarization phase, sodium ions enter the cell through the open ion-channels (Na+ influx).
Define the term depolarization?
Depolarization is a term used in biology. It is the change in or loss of polarity or polarization in a cell by removing some of the negative charges.
A wet cell is an electrochemical cell in which the electrolyte is a?
true
Describe the action of depolarization and repolarization?
Depolarization is due to the influx of Na+ which causes the cell's internal membrane to become more positive, leading to an action potential. Repolarization occurs when K+ leaves the cell causing the interior of the cell to become negative again.
Is acid an electrolyte for a dry cell?
no; it is for a wet cell instead
What cell structure is used to prepare for depolarization?
Sodium potassium pump
The bending of sterocilia toward the direction of the kinocilium of a hair cell causes?
depolarization
What ion is released within the myocardial cell with the depolarization and acts on the contractile proteins causing the cell to contract?
myosin?
What are the cells called that initiate sperm cell production?
The spermatogonia are the cells that initiate spermatozoa
Is depolarization the same as contraction in the heart?
The nerve impulse causes the release of acetylcholine from the motor end plate. This causes the depolarization of the membrane of the adjacent muscle cell.
