MCQ on Vitamins: Water Soluble & Fat Soluble Vitamins

Ans. C

Explanation: Vitamins have just been divided into two categories based on their solubilisation: Fat-soluble vitamins are stored in fat cells and should be eaten with fat. Vitamins A, D, E, and K are fat-soluble vitamins. Water-soluble vitamins aren't stored in our cells since they are expelled in large amounts through urine. As a result, it is better to replenish these vitamins regularly. Vitamins B and C are water-soluble vitamins.

Ans. D

Explanation: Beriberi, commonly known as thiamine deficiency, is an illness caused by a vitamin B1 deficiency. It is more common in underdeveloped nations among persons who eat a diet heavy in white rice or processed carbs. The leading cause of beriberi is a thiamine deficient diet. In areas where vitamin-enriched foods, such as particular cereals and loaves, are available, the condition is quite rare.

Ans. D

Explanation: Vitamins are necessary for tiny portions in the diet to boost growth, fertility, and wellbeing. Vitamins A, D, E, and K are fat-soluble vitamins because they can dissolve in organic solvents and are digested and spread similarly to fats.

Ans. A

Explanation: Vitamin B3 is a water-soluble vitamin with Niacin's chemical term. It is a crucial vitamin. It is, in fact, essential for the proper working of every component of your body. Niacin, taken as a supplement, may help decrease cholesterol, relieve arthritis, and improve cognitive function, among other things.

Ans. C

Explanation: Pellagra is a disorder caused by a deficiency in vitamin B-3, often known as niacin. It can produce various symptoms, with diarrhea, dermatitis, and dementia most prevalent. If not identified and cured early, pellagra can be fatal. Adding Vitamin B3 into your diet can protect you from pellagra disease. 

Ans. A

Explanation: Vitamin A, commonly known as retinol, is fat-soluble alcohol found in abundance in fish, particularly fish liver oils. Vitamin A is also present in milk, egg whites, and liver, and margarine contains synthetic vitamin A. Retinoic acid is also required for the efficient immune function and the preservation of epithelial for sperm production.

Ans. D

Explanation: Vitamin C may be found in various fruits, including the following.

1. Tomatoes
2. Papaya
3. Guava

Vitamin C is required for:

It helps to make the skin, bone, and tissue healthy and can aid in wound healing and infection prevention, assisting in the absorption of iron from meals. 

Ans. C

Explanation: Some water-soluble vitamins can have adverse side effects if taken in overdoses. When ingested in large amounts of 1–3 grams per day as vitamin B3, B3 can cause high blood pressure, stomach discomfort, impaired eyesight, and liver disease.

Ans. B

Explanation: Pantothenic acid is a part of coenzyme A. The acyl protein is part of the fats synthesis complex and also contains pantothenic acid. Consequently, absorbed pantothenic acid must first be liberated from coenzyme A and ACP, a process involving peptidases and nucleosidases.

Ans: D

Explanation: Megaloblastic Anaemia is caused by a vitamin B12 or folic acid shortage. Insufficient intake of specific B vitamins or poor intestinal permeability can cause a deficit. Megaloblastic Anemias are caused by drugs or genetic deficiencies in vitamin B12 or folic acid delivery and metabolism.

Ans: B

Explanation: Vitamin K aids in the production of many proteins required for blood clotting and bone formation. Prothrombin is a vitamin K-dependent protein that aids in the coagulation of blood. Vitamin K is present in the liver, brain, heart, pancreas, and bones, among other places. 

Ans: a

Explanation: Warfarin is a rat toxicant that prevents the vitamin K-dependent carboxylation of prothrombin and is applied as an anticoagulant in therapeutic practice. Dicoumarol, a coumarin derivative, is just another anticoagulant. Dicoumarol is hydroxycoumarin methane with two hydrogens,each replaced by a 4-hydroxycoumarin-3-yl group.
