Which of these is a fat-soluble vitamin stored in the liver?
Correct Answer: B. Vitamin A
Vitamins A, D, E, and K are fat-soluble and can be stored in the body's fatty tissues and liver. This means they do not need to be consumed every single day as the body can use its reserves. Excessive intake of these vitamins can, however, lead to toxicity.
Which nutrient is the primary component of 'Enzymes' that catalyze reactions in our body?
Correct Answer: B. Proteins
Almost all enzymes are proteins that speed up chemical processes like digestion and metabolism. They are highly specific and work best under certain temperature and pH conditions. Without enzymes, life-sustaining reactions would be too slow to occur.
Which vitamin is destroyed most easily during the process of cooking or heating food?
Correct Answer: C. Vitamin C
Vitamin C is highly sensitive to heat and light, and it can also leach out into cooking water. To preserve the Vitamin C content, it is best to eat fruits and vegetables raw or lightly steamed. It is the most unstable of all vitamins.
Which mineral helps in maintaining the 'Water Balance' of the human body?
Correct Answer: B. Sodium
Sodium is an electrolyte that regulates the amount of water in and around your cells. It helps maintain blood pressure and is essential for muscle and nerve function. Most people get more than enough sodium through common salt.
What is the common term used for the mixture of food and saliva in the mouth?
Correct Answer: A. Bolus
Bolus is the small, rounded mass of chewed food that is ready to be swallowed. Saliva softens the food and begins the chemical digestion of starch. The bolus then travels down the esophagus to the stomach.
Which nutrient is the primary source of energy for athletes during high-intensity training?
Correct Answer: C. Carbohydrates
Carbohydrates can be quickly broken down into glucose for immediate energy use by muscles. Athletes often 'carb-load' before events to maximize their glycogen stores. They are more efficient as an energy source during intense exercise than fats.
Which vitamin deficiency is associated with 'Burning Feet Syndrome'?
Correct Answer: D. Vitamin B5
Vitamin B5, also called Pantothenic acid, is involved in the synthesis of coenzyme A. A deficiency can cause numbness, tingling, and a burning sensation in the feet. It is found in a wide variety of foods, so deficiency is rare.
What is 'Kwashiorkor', a nutritional disorder seen in young children?
Correct Answer: C. Severe protein deficiency
Kwashiorkor is characterized by a swollen abdomen (edema) despite having adequate calorie intake. It occurs when a child's diet lacks enough protein for growth and fluid balance. It is common in areas where the diet is mostly starchy.
Which of these vitamins acts as a 'Coenzyme' in various metabolic reactions?
Correct Answer: C. Vitamin B Complex
The B vitamins work together to help the body convert food into energy (ATP). They act as helpers or coenzymes for various enzymes in the body's metabolic pathways. Each B vitamin has a specific role in maintaining health.
Which mineral is a key component of 'Enamel', the hardest part of the human tooth?
Correct Answer: A. Calcium
Calcium phosphate is the main mineral that provides the extreme hardness to the tooth enamel. Enamel protects the inner parts of the tooth from the wear of chewing and acidic foods. Fluoride is also important as it helps in the remineralization of enamel.
