Question

Which of the following is NOT a characteristic of cellulose?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
	**Primary Concept**: Carbohydrate Structure and Function
	**Related Topics**: Polymers, Monosaccharides, Digestion, Plant Biology
	**Prerequisites**: Basic knowledge of carbohydrates and their roles in living organisms.
## SOLUTION PATHWAY
**Given Information**:
	The question asks about characteristics that are NOT true for cellulose.
**Method & Steps**:
	1. Analyze each option based on the properties of cellulose.
		Reasoning: Evaluate each option against known facts about cellulose structure and function.
	2. Identify the incorrect statement.
		Working: Cellulose is a structural component in plants, made of glucose, and has beta-1,4 linkages. Humans cannot digest it.
		Key Point: Humans lack the enzyme to break the beta-1,4 glycosidic linkages in cellulose.
	3. Select the option that is NOT a characteristic of cellulose.
		Result: B. Provides energy for humans
		Verification: Cellulose is indigestible by humans and thus does not provide energy.
 ## OPTION ANALYSIS
[A] ✓: Composed of glucose monomers: Cellulose is a linear polymer of glucose monomers.
[B] :x: Provides energy for humans: Humans cannot digest cellulose; therefore, it does not provide energy.
[C] ✓: Forms a structural component of plant cell walls: Cellulose is a major component of plant cell walls, providing rigidity and support.
[D] ✓: Contains beta-1,4 glycosidic linkages: The glucose monomers in cellulose are linked by beta-1,4 glycosidic bonds, which humans cannot break down.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing cellulose with starch: Starch is also a glucose polymer but has alpha-1,4 linkages and is digestible by humans.
			How to avoid: Remember that cellulose is for structure in plants (beta-linkages), while starch is for energy storage (alpha-linkages).
		2. Assuming all carbohydrates are digestible by humans:  Many carbohydrates, like fiber (cellulose), are not digestible by humans.
			How to avoid: Learn the different types of carbohydrates and their digestibility.
	**Quick Tips**:
		1. 'Beta' in beta-1,4 linkage can be associated with 'building' (structural role in plants).
		2. 'Cellulose' sounds like 'cellular,' reminding you of its role in cell walls.
