  3. Choose the best answer: • Biochemistry can be defined as the science concerned with • Chemical basis of life. • Studying chromosomes. • Studying effect of drugs on cancer cells. • Studying composition of blood cells. • Biochemistry is concerned with the study of chemical reactions in: • Human. • Viruses. • Plant. • All of the above.

  4. The monomers of Proteins are called: • DNA • Fatty acids. • Amino Acids • Enzymes. • Which of the following is measured in serum and used for disease diagnosis: • DNA • Enzymes. • RNA • Cellulose.

  5. The basic monomers of DNA are: • Fatty Acids. • RNA. • Amino Acids. • Nucleotide bases • In carbohydrates, For every carbon there is: • 2 hydrogen atoms and 1 oxygen atom. • 2 oxygen atoms and 1 hydrogen • 2 hydrogen atoms and 2 oxygen • 1 oxygen atom and 1 hydrogen

  6. Complex carbohydrates are: • Carbohydrates with monomers of the same type • Carbohydrates with monomers of different type • Carbohydrate joined to non-carbohydrate molecules. • None of the above. • Sucrose is an example of : • Monosaccharide • Disaccharide • Polysaccharide • Oligosaccharide

  7. Glycogen is a polysaccharide formed of monomers of: • Galactose • Cellulose • Glucose • Maltose • The most common storage polysaccharide in plants is: • Maltose • Lactose • Fructose • Starch

  8. Which of the following is known as animal starch: • Glycogen. • Galactose • Lactose • None of the above • Write the four major classes of biomolecules: • Write 3 major functions of carbohydrates:

  9. The monomers of Lipids are called: • DNA • Fatty acids. • Amino Acids • Nucleotide bases. • Which of the following is measured in serum and used for disease diagnosis: • DNA • Enzymes. • RNA • Cellulose.

  10. In carbohydrates, For every carbon there is: • 1 hydrogen atoms and 1 oxygen atom. • 2 oxygen atoms and 1 hydrogen • 2 hydrogen atoms and 2 oxygen • 1 oxygen atom and 2 hydrogen • Glycolipids are example of : • Polysaccharides. • Carbohydrates with monomers of different type. • Complex carbohydrates. • None of the above.

  11. Fructose is an example of : • Aldose • Ketose • Polysaccharide • None of the above • Excess glucose is stored in human liver in the form of • Amylopectin • Amylose • Glycogen • Starch

  12. True or False: • Lipids are Hydrophylic in nature ( true-False) • A triglyceride is a lipid molecule (true-false) • All 20 amino acids are biologically essential (True – False)

  13. Write 3 major functions of Amino acids: • Write 3 major functions of Lipids • Mention the reason why glycogen is highly branched than starch
