This process can be illustrated by the simplified situation in which potassium ions are assumed to be inside the cell and sodium ions outside and when the initial transmembrane potential is equal to zero. When the potassium channels are opened, an increase in positive electrical charge outside ...
What does it mean for a neuron to be more permeable to sodium than potassium? According to study materials, solutes don't move across membranes; only water does. How does this explain the ions in our blood that move across to carry out nearly all life functions? Explain the process of ex...
Sodium ions are highest in: A. intracellular fluid B. interstitial fluidInterstitial Fluid:The interstitial fluid (also called the extracellular fluid) is the fluid that is found outside of cells. The interstitial fluid contains many dissolved ions such as sodium, potassium, chloride and calciu...

elegans expressing functional Pnlf-1::NLF-1::GFP exhibited GFP signals in its nervous system, with an enlarged view of a single neuron. The animal is outlined by a dashed line. (C) Confocal images of a wild-type ventral cord motor neuron coexpressing the nlf-1 genomic fragment and an ...
(Na+) is an important electrolyte in neuron function, and in osmoregulation between cells and the extracellular fluid. This is accomplished in all animals by Na+/K+-ATPase, an active transporter pumping ions against the gradient, and sodium/potassium channels.[95] Sodium is the most prevalent ...
During depolarization a. sodium ions move rapidly out of cell b. potassium ions move rapidly out of the cell c. sodium ions move rapidly into the cell d. potassium ions move rapidly into the cell Excitation-contraction coupling de...
Sodium will move outside of neurons through the assistance of a small protein in the neuron cell membrane. What type of transport is needed for sodium to move outsWhat are specialized membrane proteins that allow three sodium ions out of the cell and two potassiu...
Since the membrane potential of these cells is around −30 mV, therefore in the voltage window, there must be a continuous entry of sodium ions into the cells through the non-inactivated channels. Since the fast inward current is a sodium current, we checked its sensitivity to TTX which ...
Currently, some of the most challenging questions in the field directly accessible by modern atomistic simulations are the following: how is a great level of selectivity for the substrates/ions achieved and how is the energetics of ion transport coupled to the energetically unfavorable substrate ...
