VITAMINS AND THEIR DEFICIENCY DISEASES (Part-II)

1. ______ is mainly derived from citrus fruits and juices such as lemons, oranges and sweet limes/ mousambis. [S.S.C. JE Electrical Exam 24.03.2021 (Shift-II)]

(a) Vitamin C
(b) Vitamin E
(c) Vitamin K
(d) Vitamin B₂

Correct Answer: (a) Vitamin C

Solution:Citrus fruits are renowned for being excellent sources of Vitamin C (ascorbic acid). This vitamin is crucial for immune function, collagen synthesis, and acts as an antioxidant.

2. Which Vitamins are those if taken in excess can be dangerous as they are stored in the body? [S.S.C. Online Graduate Level (T-I) 10.09.2016 (Shift-I)]

(a) B Complex
(b) E and C
(c) A and D
(d) A, D and E

Correct Answer: (d) A, D and E

Solution:Vitamins are classified into fat-soluble and water-soluble. Fat-soluble vitamins (A, D, E, K) are stored in the body's fatty tissues and liver. Because they accumulate, excessive intake can lead to toxicity (hypervitaminosis). Water-soluble vitamins (B-complex and C) are not stored in significant amounts; any excess is typically excreted in urine, making toxicity less common, though not impossible with extremely high doses. Vitamin K is also fat-soluble but usually less toxic in excess than A, D, or E.

3. Which one of the following is a water soluble vitamin? [S.S.C. Online Graduate Level (T-I) 7.09.2016 (Shift-III)]

(a) A
(b) C
(c) D
(d) E

Correct Answer: (b) C

Solution:Vitamin C is a classic example of a water-soluble vitamin. It dissolves in water and is not stored in large quantities in the body.

A, D, E: These are all fat-soluble vitamins.

4. Which of the following is a water-soluble vitamin? [S.S.C. Online CGL (T-I) 16.08.2021 (Shift-I) S.S.C. Online CHSL (T-I) 17.03.2020 (Shift-II)]

(a) Vitamin K
(b) Vitamin A
(c) Vitamin D
(d) Vitamin C

Correct Answer: (d) Vitamin C

Solution:Vitamin C is a classic example of a water-soluble vitamin. It dissolves in water and is not stored in large quantities in the body.
Vitamin K, Vitamin A, Vitamin D: These are fat-soluble vitamins.

5. Intestinal bacteria synthesizes which of the following in the human body? [S.S.C. Online CHSL (T-I) 22.01.2017 (Shift-III)]

(a) Vitamin K
(b) Proteins
(c) Fats
(d) Vitamin D

Correct Answer: (a) Vitamin K

Solution:The beneficial bacteria in the human large intestine (gut microbiota) play a significant role in synthesizing Vitamin K₂, specifically menaquinones. While we also get Vitamin K from our diet (Vitamin K₁ from leafy greens), bacterial synthesis contributes to our overall supply.

6. Among the given nutrients, milk is a poor source of which of the following ? [S.S.C. Online Graduate Level (T-I) 10.09.2016 (Shift-I]

(a) Vitamin C
(b) Calcium
(c) Protein
(d) Carbohydrate

Correct Answer: (a) Vitamin C

Solution:Milk is a poor source of ascorbic acid (Vitamin C). It contains about 1 mg ascorbate per 100 g. Even the little Vitamin C is usually destroyed when the milk is heat treated. The richest sources of ascorbic acid are fruits and vegetables. Milk is a good source of retinol and thiamin.

7. Which of the following contains the highest amount of Vitamin C? [S.S.C. Online C.P.O.S.I. (T-I) 2.01.2017 (Shift-I)]

(a) Capsicum
(b) Grapes
(c) Tomato
(d) Lemon

Correct Answer: (d) Lemon

Solution:Lemons (and generally citrus fruits) are well-known for their very high Vitamin C content. While capsicum and tomatoes also contain Vitamin C, citrus fruits are typically richer sources. Grapes are not a primary source of Vitamin C.

8. Which of the following vitamins help in the absorption of calcium? [S.S.C. Online Graduate Level (T-I) 10.09.2016 (Shift-III)]

(a) Vitamin A
(b) Vitamin D
(c) Vitamin B
(d) Vitamin C

Correct Answer: (b) Vitamin D

Solution:Vitamin D is crucial for calcium homeostasis. It acts like a hormone, promoting the absorption of calcium from the gut into the bloodstream and regulating calcium levels in the blood, essential for bone health.

9. Cod liver oil is source of _____ . [S.S.C. Online MTS (T-I) 12.01.2017 (Shift-II)]

(a) Vitamin K
(b) Vitamin C
(c) Iodine
(d) Vitamin A

Correct Answer: (d) Vitamin A

Solution:Cod liver oil is traditionally known as an excellent natural source of fat-soluble vitamins, particularly Vitamin A and Vitamin D. The question only allows one option, and Vitamin A is a major component.

10. Cod liver oil from fish is rich in which vitamin? [S.S.C. Online Graduate Level (T-I) 9.09.2016 (Shift-II)]

Correct Answer: (e) Vitamin A and Vitamin D

Solution:Vitamin A and vitamin D are found in cod liver oil obtained from fish. 15 ml cod liver oil contains 4080 micrograms of vitamin A and 34 micrograms of vitamin D.
