Manganese plays several important roles in the body. From your list, the functions of manganese include:
- Metabolism - Manganese is involved in the metabolism of carbohydrates, amino acids, and cholesterol.
- Bone and cartilage formation - Manganese contributes to the formation of bone and cartilage.
- Wound healing - Manganese plays a role in wound healing due to its involvement in collagen synthesis.
- Antioxidant function - Manganese is a component of the enzyme superoxide dismutase, which helps protect cells from oxidative damage.
Muscle contraction is not a primary function of manganese.
Therefore, the correct selections are: metabolism, bone and cartilage formation, wound healing, and antioxidant function.
