This is the second set of practice questions on vitamins. It continues with vitamin types and solubility, the coenzymes they form, and the deficiency diseases connected to each vitamin. Work through it after Part 1 for fuller coverage of the topic.
Vitamin C deficiency leads to scurvy, characterized by bleeding gums due to impaired collagen synthesis.

Vitamin E is fat-soluble, stored in the body’s fatty tissues, unlike water-soluble vitamins like B and C.
Ref: NCERT Class 12 Chemistry > Chapter 14: Biomolecules > Topic: Vitamins - Types, Coenzymes and Deficiency Diseases - Part 2
Vitamin C (ascorbic acid) is required for the hydroxylation of proline and lysine in collagen synthesis.
Ref: NCERT Class 12 Chemistry > Chapter 14: Biomolecules > Topic: Vitamins - Types, Coenzymes and Deficiency Diseases - Part 2
Vitamin H (Biotin) deficiency impairs carboxylation reactions, as it’s a coenzyme for carboxylases.
Ref: NCERT Class 12 Chemistry > Chapter 14: Biomolecules > Topic: Vitamins - Types, Coenzymes and Deficiency Diseases - Part 2
Vitamin E (tocopherol) acts as an antioxidant, protecting cell membranes from oxidative damage.
Ref: NCERT Class 12 Chemistry > Chapter 14: Biomolecules > Topic: Vitamins - Types, Coenzymes and Deficiency Diseases - Part 2
Scurvy is caused by a deficiency of vitamin C (ascorbic acid), which is crucial for collagen synthesis.
Ref: NCERT Class 12 Chemistry > Chapter 14: Biomolecules > Topic: Vitamins - Types, Coenzymes and Deficiency Diseases - Part 2
Vitamin B₁₂ deficiency leads to macrocytic anemia due to impaired DNA synthesis in red blood cell production.
Ref: NCERT Class 12 Chemistry > Chapter 14: Biomolecules > Topic: Vitamins - Types, Coenzymes and Deficiency Diseases - Part 2
Vitamin B₁₂ (cobalamin) deficiency causes pernicious anemia due to impaired red blood cell production.
Ref: NCERT Class 12 Chemistry > Chapter 14: Biomolecules > Topic: Vitamins - Types, Coenzymes and Deficiency Diseases - Part 2
Vitamin B₁ (Thiamine), as part of TPP, aids in the decarboxylation of pyruvate to acetyl-CoA.
Ref: NCERT Class 12 Chemistry > Chapter 14: Biomolecules > Topic: Vitamins - Types, Coenzymes and Deficiency Diseases - Part 2
Vitamin K deficiency impairs the synthesis of clotting factors, leading to poor blood clotting.
Ref: NCERT Class 12 Chemistry > Chapter 14: Biomolecules > Topic: Vitamins - Types, Coenzymes and Deficiency Diseases - Part 2
Vitamin K is essential for the synthesis of clotting factors, aiding in blood coagulation.
Ref: NCERT Class 12 Chemistry > Chapter 14: Biomolecules > Topic: Vitamins - Types, Coenzymes and Deficiency Diseases - Part 2
Vitamin B₆ (Pyridoxine) is a coenzyme in amino acid metabolism, particularly in transamination reactions.
