Starch, cellulose and glycogen MCQs with solutions

10 of the 12 published questions on this topic, exactly as they appear in a test. Answers and worked solutions come with your result rather than on this page.

  1. Question 1 · difficulty L1 · recall

    The principal storage polysaccharide in plants is

    • A. starch
    • B. cellulose
    • C. glycogen
    • D. sucrose

  2. Question 2 · difficulty L2 · understanding

    Cellulose is primarily a

    • A. structural polysaccharide in plant cell walls
    • B. storage polysaccharide in animals
    • C. disaccharide
    • D. protein

  3. Question 3 · difficulty L2 · understanding

    Glycogen is best described as

    • A. a highly branched glucose-storage polysaccharide in animals
    • B. a plant cell-wall polymer
    • C. a disaccharide of glucose and fructose
    • D. a nucleic acid

  4. Question 4 · difficulty L2 · understanding

    Starch and glycogen are built mainly from

    • A. alpha-D-glucose units
    • B. beta-D-fructose units only
    • C. ribose units
    • D. amino acids

  5. Question 5 · difficulty L3 · application

    Which polysaccharide is expected to be the most highly branched?

    • A. Glycogen
    • B. Cellulose
    • C. Amylose
    • D. Neither starch nor glycogen

  6. Question 6 · difficulty L3 · application

    Which component of starch is largely unbranched?

    • A. Amylose
    • B. Amylopectin
    • C. Glycogen
    • D. Cellulose only by definition

  7. Question 7 · difficulty L3 · application

    Which polymer contains beta(1→4)-linked glucose units?

    • A. Cellulose
    • B. Amylose
    • C. Glycogen
    • D. Amylopectin

  8. Question 8 · difficulty L3 · application

    Humans digest starch readily but not cellulose mainly because humans

    • A. lack cellulase to hydrolyse beta(1→4) linkages efficiently
    • B. cannot digest glucose
    • C. lack enzymes for alpha linkages
    • D. convert cellulose directly into protein

  9. Question 9 · difficulty L4 · application

    Which pair correctly matches polymer and biological role?

    • A. Starch—plant storage; glycogen—animal storage
    • B. Cellulose—animal storage; glycogen—plant wall
    • C. Starch—animal wall; cellulose—plant storage
    • D. Glycogen—plant storage; cellulose—animal storage

  10. Question 10 · difficulty L4 · application

    A glucose polymer is highly branched and stored in liver and muscle. It is most likely

    • A. glycogen
    • B. cellulose
    • C. amylose
    • D. sucrose

Common mistakes in Starch, cellulose and glycogen

Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.

  • Assumes monomer identity alone determines polymer function.
  • Uses glucose composition alone and ignores branching, linkage and biological role.
