Scurvy is caused by deficiency of vitamin ______.
- A
A
- B
B
- C
C
- D
D
Scurvy is caused due to a deficiency of vitamin C (ascorbic acid). Vitamin C plays a crucial role in the synthesis of collagen, which is essential for the proper functioning of blood vessels, connective tissues, and wound healing. The deficiency of vitamin C leads to the breakdown of collagen, resulting in symptoms of scurvy such as fatigue, weakness, joint pain, and gum bleeding. However, deficiencies of vitamins A, B, and D do not result in scurvy. Vitamin A is essential for vision and immune function, vitamin B encompasses a group of vitamins involved in various aspects of metabolism and nervous system function, and vitamin D is crucial for calcium absorption and bone health. While deficiencies of these vitamins can cause other health issues, they do not directly contribute to the development of scurvy.
Vitamin A: A deficiency of vitamin A primarily affects vision and immune function, leading to symptoms such as night blindness and increased susceptibility to infections. However, it does not cause scurvy.
Vitamin B: The B-vitamin complex, including B1 (thiamine), B2 (riboflavin), B3 (niacin), B6 (pyridoxine), and others, plays essential roles in energy metabolism, nervous system function, and cell health. Deficiencies of these vitamins can lead to various conditions such as beriberi (thiamine deficiency), pellagra (niacin deficiency), or anemia (B12 deficiency). However, they do not cause scurvy.
Vitamin C: Scurvy is primarily caused by a deficiency of vitamin C. Vitamin C, also known as ascorbic acid, is vital for the synthesis of collagen, a protein that is crucial for the health of blood vessels, connective tissues, and wound healing. When there is a lack of vitamin C, collagen production is disrupted, leading to the breakdown of connective tissues and the manifestation of scurvy symptoms.
Vitamin D: Vitamin D is important for calcium absorption, bone health, and immune system regulation. Deficiencies of vitamin D can lead to conditions like rickets in children or osteomalacia in adults. However, vitamin D deficiency does not result in scurvy.
