Lesson Worksheet: Carbohydrates Biology

In this worksheet, we will practice describing the structure of different carbohydrates and outlining the roles of carbohydrates in organisms.

Q1:

What type of reaction occurs when two or more monosaccharides join together?

  • AReduction
  • BSubstitution
  • CCondensation
  • DHydrolysis

Q2:

What type of bond is formed between two monosaccharides when they join together to form a disaccharide?

  • APeptide
  • BPhosphodiester
  • CGlycosidic
  • DEster
  • EHydrogen

Q3:

Which of the following best describes the relationship between monosaccharides and polysaccharides?
