ATP is required to establish and maintain resting electrochemical gradients and repolarize
membranes after depolarization and synaptic transmission and is essential for a host of intracellular signaling and biosynthetic functions.
During phase 3 of the AP, the L-type Ca [sup]2+ channels close, while the slow delayed rectifier K [sup]+ channels are still open, allowing more K [sup]+ channels to open, causing the cell to repolarize
The QT interval in an ECG represents the total time needed for the ventricles to depolarize and repolarize
The impulse then passes back up the fast pathway into the atria that, because of the long transit time down the slow pathway, have had time to repolarize
As depolarization lasts longer, the membrane is unable to repolarize
, resulting in flaccid muscles.
When the cardiac cells repolarize
(reload) they exchange potassium for sodium and calcium.
The earliest repolarization occurred in posterobasal region of RV whereas the areas over the LV apex and adjacent area of the free wall were the last to repolarize
Through the specific channels, sodium, potassium, and calcium ions move across the outer cellular membrane to depolarize and repolarize
2) Calling Marcus' essay "an unnecessary, and disingenuous, attempt to repolarize
American literary culture" (para.
A primary function of this channel is to repolarize
active neurons, so activation in the presence of ethanol would inhibit neuronal activity.
