Minerals are important to the body because they?

Question

A. regulate important chemical reactions and supply the body with energy.

B. aid in the digestion of fruits.

C. regulate insulin releases and control muscle contractions.

D. give structure to bones and play an important role in heart and muscle contractions

Answer 1

D ....salts of calcium phosphorus makes bones..minerals are needed for electrolyte balance and play a role in any stimulation(nervous, muscular,heart..)
important chemical reaction areregulated by vitamins.
energy is provided by carbohydrates and fats.
digestionof of fruits by digestive enzymes(proteins).
insulin by harmones(protein)

Answer 2

Minerals is a very broad term for things like calcium, iron, selenium, fluoride, etc.

A- Minerals are not a source of energy because they don't yield calories. This answer sounds wrong.
B- Minerals do not aid in the digestion of fruits
C- Minerals do not regulate insulin secretions either.
D- The best answer in terms of calcium, a mineral. Calcium definitely gives structure to bones. Also, blood calcium levels help to control nerve impulses and muscle movement.

Answer 3

Minerals are inorganic elements that are found in both living and non-living things. Once a mineral is absorbed into a plant or animal it becomes biologically bound into the organic plant or animal system, but still remains inorganic in nature. Certain minerals are vital components of the human system, composing 4 - 5% of total body weight. Although only relatively small amounts of minerals are required, they are absolutely essential to normal mental and physical functioning. The body's only source for minerals is the diet. It must provide an adequate daily supply to maintain optimum health and fitness.

Minerals required in amounts greater than 100 mg are called 'macrominerals'. If less than 100 mg are needed for normal functioning, they are called either 'microminerals' or 'trace' minerals. In some cases, we're talking only minute quantities.
Macros include: Calcium, Potassium Sodium Phosphorus, Magnesium, Sulfur.
Micros include: Zinc, Copper, Iodine, Iron, Manganese.

Trace Mins include: Selenium, Molybdenum, Nickel, Vanadium, Chromium, Cobalt, Silicon.

Minerals in the body trigger enzymes, like an ignition key for a car. The key may be tiny by comparison, but the car is useless without it. Minerals and enzymes work together to control the responses of our muscles, the electrical impulses that surge endlessly through our nervous systems, the beating of our hearts, the delicate balance of our body fluids and many other complex events that must occur to maintain life.
Many mineral functions are interrelated with those of vitamins. For instance, phosphorus must be present for B-complex vitamins to be absorbed. Calcium could not be absorbed without vitamin D, and vitamin C enhances the absorption of iron.

Minerals also provide the stength to our skeletal structure and are important factors in digestion, the formation of antibodies and the production of hormones.

Answer 4

A because it really regulate important chemical reactions and supply the body with energy. man, u know your stuff :D
