Question

Which one of the following is resistant to enzyme action?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Resistance to enzyme degradation
	**Related Topics**: Plant cell walls, biomolecules, enzyme specificity
	**Prerequisites**: Basic knowledge of plant cell structures and enzyme function.
## SOLUTION PATHWAY
**Given Information**:
	*Question asks for a structure resistant to enzyme action.
	*Options include various plant-derived materials.
**Method & Steps**:
	1. Recall the composition and function of each plant structure.
		Reasoning: Understanding the chemical makeup of these structures helps determine their resistance to enzymes.
	2. Evaluate each option based on its known composition and resistance to degradation.
		Working: Cork contains suberin, wood fiber contains cellulose and lignin, pollen exine contains sporopollenin, and leaf cuticle contains cutin. Sporopollenin is known for its exceptional resistance to degradation.
	3. Identify the option with the most resistant structure.
		Result: Pollen exine contains sporopollenin, which is extremely resistant to enzyme action.
		Verification: Sporopollenin is a highly stable polymer known for its resistance to degradation.
## OPTION ANALYSIS
[A] :x: Cork (suberin) is relatively resistant but not as much as sporopollenin.
[B] :x: Wood fibre (cellulose and lignin) can be degraded by certain enzymes.
[C] ✓: Pollen exine (sporopollenin) is highly resistant to enzyme action.
[D] :x: Leaf cuticle (cutin) is resistant but not as resistant as sporopollenin.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing resistance to enzyme action with general durability: Some materials might be durable but not necessarily resistant to enzymes.
		2. Not knowing the specific composition of plant cell structures: This can lead to incorrect assumptions about their resistance.
	**Quick Tips**:
		1. Remember that sporopollenin is a highly stable and resistant polymer found in pollen exine.
		2. Focus on the unique chemical makeup of each structure when determining its resistance.
