What is Lithiums most common ion?
MOST COMMON IONS: +1 Lithium is a soft, silvery alkali metal and has the lowest density of any metal. The word “lithium” is derived from “lithos” (Greek for “stone”). Johan A. Arfvedson discovered lithium in Stockholm, Sweden, in 1817.

Where is sodium used in the body?
Sodium is both an electrolyte and mineral. It helps keep the water (the amount of fluid inside and outside the body’s cells) and electrolyte balance of the body. Sodium is also important in how nerves and muscles work. Most of the sodium in the body (about 85%) is found in blood and lymph fluid.
What is the charge on the inside of the membrane?
A neuron at rest is negatively charged: the inside of a cell is approximately 70 millivolts more negative than the outside (−70 mV, note that this number varies by neuron type and by species).
Why does sodium move into the cell?
3), sodium ions must enter the cell. Because moving the ion from a low concentration to a higher concentration results in a decrease in entropy, it requires an input of free energy. Protein transporters embedded in the membrane are capable of using an energy source to move the molecule up a concentration gradient.
Why is equilibrium potential of sodium positive?
Because of this, the sodium equilibrium potential—the electrical potential difference across the cell membrane that exactly balances the Na+start text, N, a, end text, start superscript, plus, end superscript concentration gradient—will be positive. The channels open and Na+ can move through them.
What is the equilibrium potential of sodium?
~+60 mV
What is the threshold value of muscle cells?
Definition: The membrane voltage that must be reached in an excitable cell (e.g., neuron or muscle cell) during a depolarization in order to generate an action potential. At the threshold voltage, voltage-gated channels become activated. Threshold is approximately −50 to −40 mV in most excitable cells….
What is the value of F in Nernst equation?
Nernst equation is a general equation that relates the Gibbs free energy and cell potential in electrochemistry. It is very helpful in determining cell potential, equilibrium constant etc. At standard temperature T = 298 K, the 2.303RTF, term equals 0.0592 V.
