Which describes the complex carbohydrate cellulose ?
A) It’s composed of a complex arrangement of glucose molecules
B) it’s composed of a complex arrangement of many kinds of macromolecules
C) it’s composed of a complex arrangement of chitin molecules
D) it’s composed of a complex arrangement of multi disaccharides
The correct answer is A) It's composed of a complex arrangement of glucose molecules.
To determine the correct answer, you need to understand what cellulose is and its composition. Cellulose is a type of complex carbohydrate and is the main structural component of plant cell walls. It is made up of a complex arrangement of glucose molecules.
To arrive at this answer, you can eliminate options B, C, and D, as they are incorrect. Option B suggests that cellulose is composed of many kinds of macromolecules, which is not true. Option C incorrectly states that cellulose is composed of chitin molecules, which is a different type of complex carbohydrate found in the exoskeleton of arthropods. Option D implies that cellulose is composed of multi disaccharides, but cellulose is actually made up of many individual glucose molecules linked together.
Therefore, option A is the correct answer because cellulose is indeed composed of a complex arrangement of glucose molecules.
