Question

Warburg effect has not been observed in

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [D]
## CONCEPT FRAMEWORK
	**Primary Concept**: Warburg effect in plants
	**Related Topics**: Photorespiration, C3 and C4 photosynthesis, plant biochemistry
	**Prerequisites**: Basic understanding of photosynthesis and the Warburg effect
## SOLUTION PATHWAY
**Given Information**:
	The question asks where the Warburg effect is *not* observed.
	Options include different types of plants.
**Method & Steps**:
	1. Recall the definition of the Warburg effect: Increased oxygen consumption and decreased carbon dioxide fixation at high oxygen concentrations.
	Reasoning: This effect is associated with photorespiration, which is more prominent in C3 plants.
	2. Recognize that Maize, Sugarcane, and Sorghum are all C4 plants.
	Reasoning: C4 plants have a mechanism to concentrate CO2 around Rubisco, thus minimizing photorespiration and therefore the Warburg effect.
	3. Conclude that the Warburg effect is not observed in any of these plants.
	Result: Since the effect is not observed in any of the plants individually, the correct answer is 'All of these'.
 ## OPTION ANALYSIS
[A] :x: Maize is a C4 plant, therefore the Warburg effect is minimized.
[B] :x: Sugarcane is a C4 plant, therefore the Warburg effect is minimized.
[C] :x: Sorghum is a C4 plant, therefore the Warburg effect is minimized.
[D] ✓: The Warburg effect is not observed in any of the listed C4 plants.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing C3 and C4 plants.
		[How to avoid]: Remember that C4 plants have specialized mechanisms to reduce photorespiration.
		2.[Error 2]: Assuming the Warburg effect is prominent in all plants.
		[How to avoid]: Understand that C4 photosynthesis minimizes the Warburg effect.
	**Quick Tips**:
		1.[Helpful shortcut]: C4 plants generally do not show a prominent Warburg effect due to their CO2 concentrating mechanisms.
		2.[Memory aid]: Remember that C4 plants like Maize, Sugarcane, and Sorghum are adapted to minimize photorespiration.
