Which mineral contributes to muscle function and is represented by the symbol Mg?

Magnesium, represented by the symbol Mg, plays a crucial role in muscle function. It is involved in muscle contraction and relaxation processes. Magnesium acts as a cofactor for various enzymes involved in energy metabolism and is essential for the proper functioning of muscle fibers. When muscles contract, they require energy in the form of ATP, and magnesium is necessary for the conversion of ATP to muscle energy. An adequate level of magnesium helps prevent muscle cramps and supports overall muscle health and performance.

Calcium, sodium, and potassium also contribute to muscle function but do so through different mechanisms. Calcium is vital for muscle contraction, sodium helps in nerve signaling that triggers contractions, and potassium is necessary for maintaining electrical balance in muscle cells. However, magnesium specifically supports the biochemical processes that allow for effective muscle performance, making it the correct choice in this context.
