  2. Justify the statement- “Except for Vitamin B 12 , all other vitamins should be supplied regularly in diet”.

  3. What do you mean by ‘reducing sugars’?

  4. Amino acids are alkaline, neutral or acidic”-How can this happen

  5. Name the product of hydrolysis of lactose.

  6. What are the ultimate products of digestion of proteins

  7. Write the structure of product obtained when glucose is oxidised with nitric acid

  8. What are biocatalysts

  9. What is the fullforms of RNA and DNA

  10. Why cannot Vitamin C be stored in our body

  11. Name the deficiency disease that resulting from lack of Vitamin A and Vitamin E

  12. What are the three types of RNA molecule that perform different functions?

  13. Give two examples of water soluble vitamins

  14. Name the components of α-glucose that make up starch.

  15. Give 2 examples for biocatalysts

  16. Name the component of starch, that is insoluble and also a branched polymer of α-glucose

  17. Name the water soluble vitamin, which is a powerful antioxidant. Give its one natural source

  18. Name the component of starch that is soluble in water.

  19. Name the vitamin whose deficiency causes pernicious anaemia

  20. Name the vitamin whose deficiency causes convulsions

  21. Give any two good sources of Vitamin A.

2 Marker

  1. Write the product obtained when D-glucose reacts with NH 2 OH. Explain-“Amino acids show amphoteric behaviour

  2. Identify the monosaccharide: Maltose, Fructose, Starch, Cellulose Write the name of vitamin, whose deficiency causes bleeding of gums.

  3. What type of bonding stabilizes the α-helix structure of proteins Write the product obtained,when D-glucose reacts with HCN

  4. Give the name of disease caused by deficiency of vitamin B 1 Identify the oligosaccharide: Starch, Glucose, Maltose, Fructose

  5. How are Vitamins classified into? Explain.

  6. Define the below given terms: Nucleoside and Enzymes

  7. Define: Vitamins and polysaccharides Give the difference between nucleoside and nucleotide Why are Vitamin C and Vitamin A important for us

  8. Explain: Peptide Linkage and Pyranose structure of glucose.

  9. Give the main structural difference between DNA and RNA. Write the names of bases that are common for both DNA and RNA.

  10. Explain the following terms: Invert sugar and polypeptide

  11. What are essential and non-essential amino acids? Give one example of each type

  12. Name the products of hydrolysis of sucrose. Given reason for why sucrose is not a reducing sugar

  13. Name the type of bonding that stabilises α-helix structure in proteins.

  14. What changes occur in nature of egg protein, on boiling

  15. Name the 2 components of starch. How do they differ from each other?

3 Marker

  1. Draw the Haworth structure of α-D-(-)-Glucopyranose. Give the significance of D

and (-) here.“Glucose do not give 2,4-DNP test”. What does this indicate?

  1. (a).What is meant by secondary structure of proteins

(b).Why don’t Glucose give Schiff’s test. (c).Amino acids have high melting points, but are still water soluble”- Give reason.

  1. Mention three such properties of glucose, which cannot be explained by its open

chain structure.

  1. (a).Give one reaction of glucose that cannot be explained using its open chain

structure (b).Differentiate between Keratin and Insulin. (Give one example each for essential and non-essential amino acids.

  1. (a).Identify the polysaccharide from below: Starch, Maltose, Glucose, Fructose

(b).Write the name of disease caused by deficiency of Vitamin B 12 (c).Give one difference between α-helix and β-pleated sheet structures of protein

  1. (a).Name the base that is only found in RNA

(b).Deficiency, of which vitamin causes night blindness (c).Glucose, on reaction with HI gives n-hexane”-What does this say about the structure if glucose
