Biomolecules Question 125
Question: Which of the following is a micronutrient?
Options:
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 1000-1200 mg per day. Calcium absorption is enhanced when consumed with vitamin D, and it is important to maintain a balanced diet to ensure adequate calcium levels.
C) Phosphorus is an essential element for life, found in DNA, RNA, and ATP, and plays a critical role in energy transfer and cellular function. It is also a key component of bones and teeth.
D) Magnesium is an essential mineral involved in over 300 enzymatic reactions in the body, including energy production, protein synthesis, and muscle and nerve function. It also plays a role in maintaining healthy bones and supporting a healthy immune system.
