Question

Carbon monoxide, emitted by automobiles, prevents transport of oxygen in body due to

THIRUPATHI REDDY · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Carbon monoxide poisoning mechanism
	**Related Topics**: Hemoglobin, Oxygen transport, Chemical bonding
	**Prerequisites**: Basic understanding of blood physiology and gas exchange
## SOLUTION PATHWAY
**Given Information**:
	Carbon monoxide (CO) is emitted by automobiles
	CO prevents oxygen transport in the body
**Method & Steps**:
	1. Identify the key player in oxygen transport: Hemoglobin.
		Reasoning: Hemoglobin is the protein in red blood cells that binds to oxygen.
	2. Understand the interaction of CO with hemoglobin.
		Working: CO has a much higher affinity for hemoglobin than oxygen. This means it binds more strongly.
		Key Point: This strong binding creates a stable compound.
	3. Conclude why CO is dangerous.
		Result:  By forming a stable compound with hemoglobin, CO prevents oxygen from binding, thus hindering its transport.
 ## OPTION ANALYSIS
[A] :x: CO doesn't combine with oxygen in this context to form carbon dioxide in the blood.
[B] :x: CO doesn't destroy hemoglobin; it binds to it.
[C] :x: CO doesn't just prevent the reaction; it actively binds to hemoglobin, making it unavailable for oxygen.
[D] ✓: This is the correct answer as CO forms a stable carboxyhemoglobin compound with hemoglobin, preventing oxygen transport.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing CO's reaction with oxygen in combustion with its reaction in the blood: Avoid thinking that CO forms CO2 in the blood; it binds to hemoglobin directly.
		2. Thinking CO prevents the reaction: CO actively binds, making it unavailable for oxygen.
	**Quick Tips**:
		1. Remember CO's high affinity for hemoglobin.
		2. Visualize the competition between oxygen and CO for hemoglobin binding sites.
