Question 1

Grade 12 Biology entrance exam, 2018 E.C. (2026)

Which of the following is a major carbohydrate found in plants that humans cannot digest?

  1. A.Glycogen
  2. B.Fructose
  3. C.Cellulose
  4. D.Maltose
Show the answer and explanation

Answer: C Cellulose

Why

Plants store energy as starch and build their cell walls from cellulose. Both are chains of glucose, but the glucose units in cellulose are joined by beta 1,4 links, and the human gut makes no enzyme that can cut that link. So cellulose passes through us as dietary fibre. Glycogen tempts because it is also a glucose polymer, but it is the animal storage carbohydrate and our amylase and maltase break it down without trouble.
