EPP (end plate potential) is a physical term used in physiology and biophysics to describe the change in potential at the surface of a cell membrane. PEP measures the level of potentials that arise on the membrane and between cells as a result of chemical reactions.
PEP can be used to study various processes in cells, such as the transmission of nerve impulses, muscle contraction, transport of substances across the membrane, and many others. PEP measurements can also be used to analyze the mechanisms of action of drugs and other compounds.
However, it is important to understand that PEP is not the only method for measuring potentials at the surface of the cell membrane. There are other methods such as electrometry and microelectrode measurements. Each of these methods has its own advantages and disadvantages, and the choice of method depends on the specific research problem.
One example of the application of PEP is the study of the electrical characteristics of nerves in living organisms. Nerve signals are transmitted through electrical impulses that induce EPPs on the surface of the postsynaptic membrane (postsynaptic terminal membrane) near the synapse. Studying PEP allows scientists to gain insight into how
