Fat Soluble Vitamin Quiz Question And Answers

Vitamin D is synthesized in the body through exposure to sunlight. It can also be obtained from dietary sources such as fortified milk or margarine, liver, sardines, salmon, and shrimp. Therefore, these sources are rich in Vitamin D.

Rickets and Osteomalacia are both conditions that are caused by a deficiency of Vitamin D. Vitamin D plays a crucial role in the absorption of calcium and phosphorus, which are essential for the development and maintenance of strong bones. A lack of Vitamin D can lead to weakened bones, bone deformities, and increased risk of fractures. Therefore, the correct answer is Vitamin D.

Vitamin A is essential for various functions in the body including vision, health of the cornea, epithelial cells, mucous membranes, skin, bone and tooth growth, regulation of gene expression, reproduction, and immunity. It plays a crucial role in maintaining good vision, promoting healthy skin, supporting the immune system, and aiding in the growth and development of bones and teeth. Vitamin A also helps in the production of certain proteins that are necessary for normal cell function and differentiation.

Vitamin D is responsible for the mineralization of bones by increasing the absorption of calcium and phosphorus from the digestive tract. It also helps in withdrawing calcium from bones and stimulating its retention by the kidneys. Vitamin A, Vitamin E, and Vitamin K do not have a direct role in bone mineralization.

The given sources such as fortified milk, cheese, cream, butter, fortified margarine, eggs, and liver are all rich in Vitamin A. Vitamin A is essential for maintaining healthy vision, promoting growth and development, and supporting the immune system. It also plays a role in maintaining the health of skin and mucous membranes. Therefore, these food sources are recommended for individuals looking to increase their intake of Vitamin A.

Hypovitaminosis A is a condition that occurs due to a deficiency of Vitamin A. Vitamin A is an essential nutrient for maintaining healthy vision, immune function, and cell growth. A lack of this vitamin can lead to various symptoms such as night blindness, dry skin, and impaired immune function. Therefore, the correct answer is Vitamin A.

Spinach and other dark, leafy greens, broccoli, and deep orange fruits and vegetables are good sources of beta-carotene. Beta-carotene is a precursor to vitamin A in the body, meaning that it can be converted into vitamin A. Therefore, the correct answer is Vitamin A.

Vitamin K is the correct answer because it is involved in the synthesis of blood clotting proteins, which are essential for the process of blood clotting to prevent excessive bleeding. Additionally, vitamin K is also important in the synthesis of proteins that play a crucial role in bone mineralization, helping to maintain strong and healthy bones.

Vitamin D is the correct answer because excessive intake of this vitamin can lead to toxicity, causing raised blood calcium levels, calcification of blood vessels and heart tissues, calcification of tooth soft tissues, thinning of tooth enamel, excessive thirst, headaches, irritability, loss of appetite, weakness, nausea, kidney stones, calcification of soft tissues such as the kidneys, lungs, and joints, and mental and physical retardation of offspring.

Vitamin E is the correct answer because it functions as an antioxidant, which means it helps to neutralize harmful free radicals in the body. It also plays a role in stabilizing cell membranes, supporting immune function, protecting polyunsaturated fatty acids, and promoting normal nerve development.

Vitamin K is the correct answer because it plays a crucial role in blood clotting. Anti-clotting medicines, such as warfarin, work by inhibiting the action of vitamin K, thus preventing excessive blood clotting. Therefore, an increase in vitamin K intake can interfere with the effectiveness of these medications and potentially increase the risk of blood clots.

Polyunsaturated plant oils, green and leafy vegetables, wheat germ, whole grain products, nuts, and seeds are all rich sources of Vitamin E. Vitamin E is a fat-soluble vitamin and acts as an antioxidant in the body, protecting cells from damage caused by free radicals. It is important for maintaining healthy skin, eyes, and immune function. Consuming foods high in Vitamin E can help meet the body's requirements for this essential nutrient.

Bacterial syntheses in the digestive tract, as well as green leafy veggies, cabbage type veggies, soybeans, and vegetable oils, are sources of Vitamin K.

Vitamin E toxicity can cause various symptoms including augmenting the effects of anti-clotting medications, general discomfort, nausea, blurred vision, and fatigue. Excessive intake of Vitamin E can interfere with blood clotting and increase the risk of bleeding. It can also cause gastrointestinal discomfort, blurred vision, and fatigue. Therefore, the correct answer is Vitamin E.
