Multiple Choice
Which of the following is true of both starch and cellulose?
A
Both are digestible by humans.
B
Both are linear polymers.
C
Both have alpha-glycosidic linkages.
D
Both are composed of glucose monomers.
Verified step by step guidance
1
Understand the basic structure of starch and cellulose: Both are polysaccharides composed of glucose monomers.
Recognize the type of glycosidic linkages: Starch has alpha-glycosidic linkages, while cellulose has beta-glycosidic linkages.
Consider the digestibility by humans: Starch is digestible due to its alpha linkages, but cellulose is not digestible by humans because of its beta linkages.
Analyze the polymer structure: Starch can be both linear (amylose) and branched (amylopectin), whereas cellulose is a linear polymer.
Conclude that the commonality between starch and cellulose is that both are composed of glucose monomers, despite differences in linkage type and digestibility.
