What does the sodium-potassium exchange pump transfer into and out of the cell during depolarization?

The sodium potassium pump does not function during depolarization, but rather after repolarization. During repolarization, potassium ions flow out of the cell into the extracellular space to reestablish membrane polarity. What the sodium potassium exchange pump does is reestablish the initial ionic concentrations. It does this by exchanging three sodium ions inside the cell for every two potassium ions outside the cell.

This is the process in which two chromosomes exchange DNA during prophase of meiosis?
This process is called crossing over .
Chromosomes exchange genetic information through the process of what?
Chromosomes exchange genetic information during a process called crossing over. This occurs during meiosis
What carries an amino acid to a ribosome during protein synthesis?
traspfar or rna
What is a process in which homologous chromosomes exchange portions of their chromatids during meiosis?
the process in which homologous chromosomes exchange portions of their chromatids during meiosis is the definition of the term "Crossing Over"
Does tRNA transfer amino acid during translation or transcription?
tRNA transfers amino acids during tranlation while mRNA is synthesized during transcription. tRNA Transfers Amino Acids during Translation
What channels are open during depolarization and during repolarization?
During depolarization Na channels are open During repolarization K channels are open
Depolarization of the sa node occurs during?
P wave
What global transfer of food plants and animals took place during the colonization of the Americas?
The Columbian exchange.
When is a neurolemma more permeable to potassium than sodium?
during depolarization
Which is the first step in a neuron production of an action potential?
Depolarization is the first event in action potential. During depolarization, the sodium gates open and the membrane depolarizes.
What does the electrical charge on the inside of the axon become when depolarization occurs?
During depolarization, sodium ions rush into the axon, making the inside negative, and the outside positive.
During depolarization of action potential the outer part of axon becomes?
Negative
What wave of the EKG occurs during depolarization of the ventricle?
QRS
Which electrolyte flows into the cell to initiate depolarization?
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.
Does the p wave in an ekg indicate atrial depolarization?
No it does not. Atrial repolarization is generally not visible on the telemetry strip because it happens at the same time as ventricular depolarization (QRS complex). The P wave represents atrial DEpolarization (and atrial systole). Atrial repolarization happens during atrial diastole (and ventricular systole).
What term is used to define this exchange of goods between the old world and the new world?
what do they call the transfer of goods,foods and ideas between the old world and the new world during the 1500s
What happens in the neurolemma as the result of an action potential?
It provides insulation to the axons and dendrites during depolarization or action potential.
