If you planned to organize a French dinner for your guests and surprise them with frog legs, but something went wrong, and your kitchen began to turn into a kitchen from a horror movie, do not panic and move out of the house. Have you ever wondered what happens when you put salt on a frog? Do frog legs jump when you cook them?
Does frog meat move after death? Do frog legs jump when you cook them? Frog legs will jump when you cook them if they are fresh and the skin is not scratched. Galvani proved that electricity could activate frog legs, and since salt contains sodium ions, it can act just like electricity and make frog legs jump as you cook them.

When you put salt on frog legs, they will twitch and shake. Muscle fibers contain unused stores of adenosine triphosphate, a nucleotide that is the main carrier of energy in a living organism. Salt acts as an activator that releases adenosine triphosphate and makes frog legs twitch.
After the frog’s death, unused adenosine triphosphate, the main source of energy in our body, remains in the muscles. It still works, but it requires a signal from the nervous system to activate it. Galvani connected a weak source of electricity, and here salt plays its role.
Galvani discovered that a frog muscle could be made to contract by placing an iron wire to the muscle and a copper wire to the nerve. This discovery played a historical role in bioelectricity as it proved that electricity was not direct in its action.
Sodium and potassium ions in the salt are connected to the biological machine, then a cascade of reactions begins. The inner side of the membrane of a nerve cell carries a negative charge and has so-called ion channels, which selectively pass chloride and sodium ions. Outside, the charge is positive. Some of the channels are open at the beginning of the reaction. When positively charged sodium ions enter them and into the cell, the following channels open, and frog legs twitch.
Why do frog legs twitch and shake with salt? After the frog’s death, unused adenosine triphosphate, the main source of energy in our body, remains in the muscles. The muscle only needs an activator, with which the negative charge will interact. The salt is this activator, releasing triphosphate and making frog legs twitch.
If you want to check what happens when you put salt on frog legs, the frog legs should be fresh, and the skin on them should not be scratched (cells should not be damaged with sharp objects), and then this incredible biochemical machine can surprise you and your guests.
Why Do Frog Legs Twitch and Shake With Salt?
Frog’s legs cells contain an unused negative charge, which is a coenzyme found in all organisms and is used as an energy stimulant. The muscle only needs an activator, with which the negative charge will interact. The amount of negative charge in the cells is limited, so the movement will not be constant. Galvani was the first scientist to show that electricity can activate frog legs, and since salt contains sodium ions, it can create potential differences just like electricity.
Salt contains sodium and potassium ions, which are used in cells to create potential differences. A nerve signal, or action potential, is the coordinated movement of sodium and potassium ions across the nerve cell membrane.
Why Do Frog Legs Shake With Salt Explained — What Happens When You Put Salt On A Frog?
- The inner part of the frog’s cell is slightly negatively charged (resting membrane potential-70 to-80 millivolts).
- Excitement (mechanical, electrical, or sometimes chemical) causes several sodium channels in a small part of the membrane to open.
- Sodium ions enter the cell through the open sodium channels. The positive charge they carry makes the inside of the cell less negative (depolarizes the cell).
- When depolarization reaches a certain threshold value, many more sodium channels in that open area. The ingestion of most of the sodium produces an action potential. The influx of sodium ions reverses the membrane potential in that area (making it positive on the inside and negative on the outside — the electric potential goes about +40 millivolts on the inside)
As in the case of the “dancing” octopus, a chemical reaction leads to the twitching of the frog’s muscles. Muscle fibers contain unused stores of adenosine triphosphate, a nucleotide that is the main carrier of energy in a living organism. Salt acts as an activator that releases adenosine triphosphate. Since the amount of unused nucleotide is limited, the “dance” of frog legs does not last long.
