1. The following metal ion activates many enzymes, participates in the oxidation of glucose to produce ATP and with $Na$, is responsible for the transmission of nerve signals.
(a) Copper
(b) Calcium is an essential mineral that plays a crucial role in maintaining strong bones and teeth, supporting muscle function, and facilitating nerve signaling in the body. It is also vital for blood clotting and the release of hormones. A deficiency in calcium can lead to conditions such as osteoporosis, while excessive intake may result in hypercalcemia. Good dietary sources of calcium include dairy products, leafy green vegetables, and fortified foods. The recommended daily intake varies by age and gender, with adults generally needing around 1000-1300 milligrams per day. Calcium absorption is enhanced when consumed with vitamin D, which helps the body utilize calcium more effectively.
(c) Potassium is an essential mineral that plays a key role in maintaining fluid balance, nerve signaling, and muscle contractions. It also helps regulate blood pressure and supports proper functioning of the heart. A deficiency in potassium can lead to symptoms such as muscle weakness, cramps, and irregular heartbeats. Good dietary sources of potassium include bananas, oranges, spinach, potatoes, and tomatoes. The recommended daily intake for adults is approximately 2,600-3,400 milligrams, which can typically be achieved through a balanced diet.
