Question

Scurvy is caused by the deficiency of
(A) Ascorbic acid
(B) Glutamic acid
(C) Vitamin $B_2$
(D) Vitamin $B_{12}$

Answer 1

Hint : When compared to other dietary deficits, scurvy is a rare occurrence. It is more common in underdeveloped countries and is linked to malnutrition. According to reports, refugee rates range from 5% to 45 percent. Scurvy has been documented from the time of ancient Egypt. It was a stumbling block to long-distance marine transport, killing vast numbers of people in the process. During the Age of Sail, it was estimated that 50% of sailors would succumb to scurvy during a long voyage.

Complete Step By Step Answer:
Scurvy is an illness caused by a deficiency of vitamin C. (ascorbic acid). Weakness, fatigue, and painful arms and legs are early signs of deficiency. Reduced red blood cells, gum problems, hair changes, and skin bleeding may result if left untreated. Scurvy can cause poor wound healing, personality changes, and death from infection or bleeding as it progresses. Before symptoms appear, it takes at least a month of eating little or no vitamin C. Scurvy is especially frequent in those with mental illnesses, strange dietary habits, drunkenness, and elderly individuals who live alone in modern times. Vitamin C (also known as ascorbic acid or ascorbate) is a water-soluble vitamin that may be found in a variety of foods and is also available as a dietary supplement. Scurvy is a disease that may be prevented and treated with this supplement. Vitamin C is a necessary component for tissue healing and the enzymatic synthesis of some neurotransmitters. It is vital for immune system function and is essential for the operation of numerous enzymes. It also has antioxidant properties. Humans, apes, most bats, and some rodents and other animals, on the other hand, are unable to synthesize vitamin C and must obtain it via dietary sources. Vitamin C is well tolerated by the majority of people.
Hence option A is correct.

Note :
Vitamin C is an important vitamin for humans and other animals. Vitamin C refers to a group of vitamins that have vitamin C action in animals. Some dietary supplements contain ascorbate salts such as sodium ascorbate and calcium ascorbate. When they are digested, they release ascorbate. Because the forms interconvert according to pH, both ascorbate and ascorbic acid are naturally present in the body. Reducing agents convert oxidised versions of the molecule, such as dehydroascorbic acid, back to ascorbic acid.
