Abstract:
K+ channels exist in all living systems. They allow a selective transition to the K+ ion, which enables the activity of various vital tissues such as muscle cells, neurons, and even bacteria and plants. Despite the mechanism variation in the gating process of K+ channels in different tissues, the selectivity for the K+ ion is preserved and the electrochemical cascade is maintained in these tissues. The electrochemical gradient of the K+ ion is very close to the diffusion rate of K+ ions in bulk water. On the molecular level, how does a K+ ion move across the ion conduction pathway? There are many molecular models that describe and answer this question, however, this is rarely described on the macro level. Here, a physical model can serve as a very good basis for enabling a deeper understanding of the K+ ion for ion transport. Classical physical energy and linear and angular momentum laws can provide a good explanation as to how and what happens to K+ ions when they pass through an ion conduction pathway. This model describes the passage of the ion even before it enters the ion conduction path until the last ion at the end exits. The simulation described here is fascinating and depicts the state of the ion at the farthest end released at almost the same speed as the first ion initially, while all the other ions remain almost at rest. How does this occur? What happens if we change the size or mass of the ion? In this work, I describe this principle and the related problems that could be studied.

The Role of Ion Channels in Neuronal Computation
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....
Electrochemical Gradient and Channel Proteins: An Overview
The electrical gradient: The electrical gradient across cell membranes refers to the difference in electric charge between the inside and outside of a cell. This difference drives the movement of ions towards or away from the cells. For instance, if the inside of the cell is more negatively charged relative to...
Voltage-gated Ion Channels
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several...
