Questions and Answers
  • 1. 

    Which of the following is not a fat-soluble vitamin?      

    • A.

      Vitamin A

    • B.

      Vitamin C

    • C.

      Vitamin D

    • D.

      Vitamin E

    Correct Answer
    B. Vitamin C
    Explanation
    Vitamin C is not a fat-soluble vitamin. Fat-soluble vitamins are those that can be dissolved in fats and oils, and are stored in the body's fatty tissues. Vitamin C, on the other hand, is a water-soluble vitamin, meaning it dissolves in water and is not stored in the body. It is important for immune function, collagen synthesis, and acts as an antioxidant.

    Excess fat-soluble vitamins typically accumulate in the:

    • A.

      Liver

    • B.

      Muscle

    • C.

      Small intestine

    • D.

      Pancreas

    Correct Answer
    A. Liver
    Explanation
    Excess fat-soluble vitamins typically accumulate in the liver because the liver is responsible for the storage and metabolism of these vitamins. Fat-soluble vitamins, such as vitamins A, D, E, and K, are absorbed in the small intestine and then transported to the liver where they are stored for future use. The liver plays a crucial role in regulating the levels of these vitamins in the body, ensuring that they are available when needed. Accumulation of excess fat-soluble vitamins in the liver can lead to toxicity and potential health problems.

    • A.

      Fortification

    • B.

      Pasteurization

    • C.

      Enrichment

    • D.

      Modification

    Correct Answer
    C. Enrichment
    Explanation
    Enrichment refers to the process of replacing lost nutrients in foods. It involves adding essential vitamins and minerals to food products to enhance their nutritional value. This is commonly done to prevent nutrient deficiencies and improve the overall nutritional content of the food. Fortification, on the other hand, refers to the addition of nutrients that are not naturally present in the food, while pasteurization is a heat treatment process to kill bacteria. Modification is a general term that does not specifically relate to replacing lost nutrients in foods.

    Too much water in spaces surrounding cells is known as:

    • A.

      Osmosis

    • B.

      Ions

    • C.

      Edema

    • D.

      Cations

    Correct Answer
    C. Edema
    Explanation
    Edema refers to the condition of excessive water accumulation in the interstitial spaces surrounding cells. This can occur due to various reasons such as inflammation, injury, or certain medical conditions. The excess fluid causes swelling and can lead to discomfort and impaired tissue function. Osmosis, on the other hand, is the movement of water across a semi-permeable membrane, ions are electrically charged particles, and cations specifically refer to positively charged ions. Therefore, edema is the correct term for the described condition of excessive water in spaces surrounding cells.

    Which mineral is responsible for making muscles contract or relax?

    • A.

      Boron

    • B.

      Magnesium

    • C.

      Sodium

    • D.

      Calcium

    Correct Answer
    D. Calcium
    Explanation
    Calcium is responsible for making muscles contract or relax. When calcium ions are released into muscle cells, they bind to proteins that are involved in muscle contraction, allowing the muscles to contract. When calcium ions are removed from the muscle cells, the proteins relax, causing the muscles to relax. Therefore, calcium plays a crucial role in the contraction and relaxation of muscles.

    Which mineral is known for transporting oxygen in the blood?

    • A.

      Iron

    • B.

      Zinc

    • C.

      Copper

    • D.

      Calcium

    Correct Answer
    A. Iron
    Explanation
    Iron is known for transporting oxygen in the blood. This is because iron is a key component of hemoglobin, a protein found in red blood cells that binds to oxygen and carries it from the lungs to the rest of the body. Without iron, the body would not be able to effectively transport oxygen, leading to a condition called iron deficiency anemia.

    Which mineral deficiency is the most common worldwide?

    • A.

      Sodium

    • B.

      Phosphorus

    • C.

      Iron

    • D.

      Calcium

    Correct Answer
    C. Iron
    Explanation
    Iron deficiency is the most common mineral deficiency worldwide because iron is essential for the production of hemoglobin, the protein in red blood cells that carries oxygen to the body's tissues. Without enough iron, the body cannot produce enough healthy red blood cells, leading to a condition called iron deficiency anemia. Iron deficiency is particularly common in developing countries where diets may lack iron-rich foods and in populations with limited access to healthcare and proper nutrition. Symptoms of iron deficiency include fatigue, weakness, pale skin, and impaired cognitive function.

    Over 99% of calcium in the body is found within the:

    • A.

      Liver and spleen

    • B.

      Muscles and skin

    • C.

      Bones and teeth

    • D.

      Stomach and small intestine

    Correct Answer
    C. Bones and teeth
    Explanation
    Calcium is a vital mineral for the body, and it is primarily stored in the bones and teeth. These structures serve as reservoirs for calcium, which is constantly being deposited and withdrawn from them to maintain the body's calcium balance. The liver and spleen play important roles in various bodily functions, but they do not store significant amounts of calcium. Similarly, while muscles and skin contain some calcium, it is not the primary location for its storage. The stomach and small intestine are involved in the absorption of calcium from food, but they do not store it. Therefore, the correct answer is bones and teeth.
