Question

Quizplus · Accepted Answer

Calcium provides rigidity for the bones and teeth, making up a significant portion of their composition. Only a small fraction of the body's calcium is involved in nerve impulse transmission and muscle contraction. Calcium does not provide energy for cells. Calcium provides rigidity for the bones, making up approximately 99% of the body's calcium supply. It also plays a role in muscle contraction and nerve transmission, but these functions use a much smaller portion of the body's calcium supply.
