Question

Which one is not essential micronutrient
A. Boron
B. Sodium
C. Manganese
D. Molybdenum

Answer 1

Nutrients which are needed for the body for good nutritional status are provided by the food. Nutrition status is checked by eating food. These are organic and inorganic complexes. Examples include proteins, fats, carbohydrates, vitamins, and minerals. Nutrients are present in food that provide us with energy and facilitate repair , growth and help to carry out various life processes.

Complete step by step answer: Macronutrients are carbohydrates, proteins and fats which are often called as proximate principles because they form the main bulk of the food.

MICRONUTRIENTS- These are vitamins and minerals .They are called micronutrients because they are required in very small amounts. Some of these are listed below:
-Vitamin A (Retinol)- Necessary for normal vision and immunity.
-Thiamine (Vitamin B1)- Help to release energy from protein and carbohydrates.
-Riboflavin (Vitamin B2)- It helps in release of energy from proteins fat and carbohydrates.
-Vitamin C- Antioxidant in blood and cells.
-Vitamin D- Maintains calcium and phosphorus balance.
-Vitamin E- Antioxidant in cell membranes.
-Vitamin K- Assists in blood clotting.
-Calcium- Structural component of bones and teeth and muscle contraction.
-Chromium- Assists insulin action.
-Copper- Assists in energy production and iron utilization.
-Fluoride- Structural component of bones and teeth.
-Iodine- Component of thyroid hormones.
-Manganese- Component of antioxidant enzymes and proteins.

MACRONUTRIENTS- Required by the body in large amounts. These are carbohydrates proteins and fats
Carbohydrates are the body’s preferred energy source .
Proteins are very necessary for human as well as animal body growth.
The most energy-dense of the macronutrients is fat.
Sodium is not an essential micronutrients. Excess sodium increases blood pressure and many other diseases too. So, the correct answer is option (B).

Note: Micronutrients are those essential elements which are required by plants as well as animals in small amounts, less than 10 m mole/kg of dry matter. They are mostly involved in the functioning of enzymes; these micronutrients are required in small amounts so that these elements are called as trace elements. Micronutrients are a total eight in number and these are very useful for us as well as plants.
