Question

The respiratory quotient (RQ) is defined as the:

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [Option B]
## CONCEPT FRAMEWORK
	**Primary Concept**: Respiratory Quotient (RQ)
	**Related Topics**: Cellular respiration, Metabolism, Gas exchange
	**Prerequisites**: Understanding of metabolic processes and gas exchange in respiration
## SOLUTION PATHWAY
**Given Information**:
		- RQ is concerned with the ratio of gases involved in respiration.
		- It relates to the type of substrate being metabolized.
**Method & Steps**:
	1.	Identify the definition of RQ.
		Reasoning: RQ is a ratio that helps determine the type of fuel being oxidized for energy.
		Formula/Rule: $$ RQ = \frac{V_{CO_2}}{V_{O_2}} $$
	2.	Apply the definition to the options given.
		Working: The correct definition states that RQ is the ratio of CO2 produced to O2 consumed.
		Key Point: Correctly interpreting the ratios is crucial for understanding metabolism.
	3.	Confirm the correct option based on the definitions.
		Result: The correct definition aligns with option B.
		Verification: By understanding the metabolic process, we verify that the answer is indeed the ratio of CO2 evolved to O2 consumed.
## OPTION ANALYSIS
[A] :x: The statement is incorrect as it describes the inverse relationship.
[B] ✓: This is the correct definition of the respiratory quotient, indicating the ratio of CO2 evolved to O2 consumed.
[C] :x: This option misrepresents the concept of RQ, focusing on a rate rather than a ratio.
[D] :x: Similar to option C, this option does not relate to the definition of RQ.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing RQ with other respiratory measurements: Focus on the specific ratio.
		2. Misunderstanding the significance of the ratio in metabolic contexts: Remember that it reflects substrate utilization.
	**Quick Tips**:
		1. Remember the acronym RQ as "Ratio of CO2 to O2" to keep the definition clear.
		2. Relate RQ values to different metabolic states (e.g., carbohydrate vs. fat metabolism) for better understanding.

Mr. NARESH KUMAR K · Answer
