Which of the following statements correctly highlights a key difference between cellulose and chitin?

  • A: Cellulose is found in plant cell walls, while chitin is found in animal cell walls.
  • B: Cellulose is a nutrient for humans, but chitin is not.
  • C: Chitin contains a nitrogen-containing appendage on its glucose monomer, which is absent in cellulose.
  • D: Cellulose forms β linkages, whereas chitin forms α linkages.

Explanation

The text states that 'Chitin is similar to cellulose, with β linkages, except that the glucose monomer of chitin has a nitrogen-containing attachment.' This clearly highlights the nitrogen-containing attachment as the key structural difference.
