Explanation / Answer

22) Starch

Starch is polysaccharide in which glucose monomers are joined by the alpha 1,4 linkage.

23) a material found in the cell walls

Cellulose is a structural polysaccharide made up of glucose molecules which are joined by the beta 1,4 linkages

24) Presence of glycerol and fatty acids

25) Both b and d but not a and c

Fructose and glucose are monosaccharide’s which are made up of six carbon atoms and they are reducing sugars.

26) All of the above

They are hexoses i.e. made up of six carbon atoms and they are monosaccharides.

27) Are monosaccharides

Glucose is a hexose and ribose is a pentose both are monosaccharides

28) A molecule of fructose and a molecule of glucose

Sucrose is a non-reducing disaccharide composed of fructose and glucose which are joined by the alpha-beta 1 2 linkage

29) Lactose

Lactose is disaccharide composed of galactose and glucose which are joined by the beta 1, 4 linkage.

30) Starch

Starch is polysaccharide in which glucose monomers are joined by the alpha 1, 4 linkage. It is storage form of polysaccharide in plants.

31) Both a and c but not b or d

Glycogen is storage form of polysaccharide in animals and made up of glucose units joined by the alpha 1,4 linkages.

32) Fats

Triglycerides are also called triacylglycerols which are made up of glycerol and three fatty acid chains.

33) Both a and b but not c or d

Oils are lipids they are liquids at room temperature and unsaturated.

34) All of the above

Lipids are a heterogeneous group of molecules soluble in organic solvents and insoluble in aqueous solvents.

35) Butter

Is an example of saturated fat due to the presence of saturated fatty acids in their structure.

36) Include fats that consist of one glycerol molecule and three fatty acid molecules

Lipids are a heterogeneous group of molecules soluble in organic solvents and insoluble in aqueous solvents.

37) Phospholipids

They are most abundant membrane lipids and responsible for the membrane fluidity.
