Worked practice questions

A carbohydrate that cannot be hydrolysed to a simpler unit is called a:

  1. Monosaccharide
  2. Monochromatic
  3. Monosyllabic
  4. Monotonously
Show answer and solution

Correct answer: A. Monosaccharide

1. Carbohydrates are classified by what hydrolysis does to them. 2. One class cannot be broken down any further. 3. A carbohydrate that cannot be hydrolysed further is called a monosaccharide. 4. Glucose, fructose and ribose are the examples given. _Source: syllabus Chemistry Part II, Ch 10 'Biomolecules'_

Carbohydrates yielding a large number of monosaccharide units on hydrolysis are:

  1. Polytechnical
  2. Polysaccharides
  3. Polychromatic
  4. Polysyllabic
Show answer and solution

Correct answer: B. Polysaccharides

1. The classes differ in how many units hydrolysis releases. 2. One class releases a very large number of them. 3. Carbohydrates which yield a large number of monosaccharide units on hydrolysis are polysaccharides. 4. Starch, cellulose and glycogen are the examples given. _Source: syllabus Chemistry Part II, Ch 10 'Biomolecules'_

The linkage between two monosaccharide units through an oxygen atom is called:

  1. Glycosidic
  2. Glycerine
  3. Glandular
  4. Gleaming
Show answer and solution

Correct answer: A. Glycosidic

1. Two sugar rings can be joined into one molecule. 2. The bridge between them runs through an oxygen atom. 3. Such a linkage between two monosaccharide units through oxygen is called glycosidic linkage. 4. So the answer is glycosidic. _Source: syllabus Chemistry Part II, Ch 10 'Biomolecules'_
