C₄ plants, such as maize and sugarcane, use the C₄ pathway to minimize photorespiration and increase CO₂ efficiency.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants Photosynthesis - Significance and Bacterial Photosynthesis
Photorespiration reduces photosynthetic efficiency and does not generate ATP or glucose; its biological function remains unclear.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants Photosynthesis - Significance and Bacterial Photosynthesis
High carbon dioxide levels reduce RuBisCO’s tendency to bind with oxygen, minimizing photorespiration.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants Photosynthesis - Significance and Bacterial Photosynthesis
Photorespiration occurs when RuBisCO binds oxygen instead of carbon dioxide.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants Photosynthesis - Significance and Bacterial Photosynthesis
Photorespiration occurs in C₃ plants when O₂ concentration is high and CO₂ concentration is low, leading RuBisCO to function as an oxygenase instead of a carboxylase.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants Chemiosmotic Hypothesis and Factors Affecting Photosynthesis
Photorespiration occurs when RuBisCO binds oxygen to RuBP, leading to energy loss.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants Chemiosmotic Hypothesis and Factors Affecting Photosynthesis
Photorespiration reduces the efficiency of photosynthesis by consuming O₂ and releasing CO₂ without ATP synthesis.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants Chemiosmotic Hypothesis and Factors Affecting Photosynthesis
Photorespiration reduces photosynthetic efficiency by consuming ATP and releasing CO2.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants Chemiosmotic Hypothesis and Factors Affecting Photosynthesis
Photorespiration results in CO2 release and ATP consumption, reducing photosynthetic efficiency.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants C4 Pathway - Hatch and Slack and Photorespiration
Photorespiration increases when oxygen levels are high and carbon dioxide levels are low.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants C4 Pathway - Hatch and Slack and Photorespiration
C₄ plants use PEP carboxylase to initially fix CO₂, reducing photorespiration by maintaining high CO₂ concentration in bundle sheath cells.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants C4 Pathway - Hatch and Slack and Photorespiration
In C₄ plants, bundle sheath cells contain RuBisCO and maintain high CO₂ concentration to prevent photorespiration.
