In C3 plants, RuBP is the primary acceptor of CO2 during the Calvin cycle.
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
In C₃ plants, CO₂ fixation leads to the formation of 3-phosphoglyceric acid (PGA) as the first stable product.
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
C₄ plants prevent photorespiration by maintaining high CO₂ levels in the bundle sheath cells, making them more efficient.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants C4 Pathway - Hatch and Slack and Photorespiration
C₃ plants have lower productivity in hot climates because they undergo high rates of photorespiration, reducing CO₂ fixation efficiency.
Ref: NCERT Class 11 Biology Chapter 11: Photosynthesis in Higher Plants C4 Pathway - Hatch and Slack and Photorespiration
RuBP captures CO2 in the Calvin cycle, forming the three-carbon compound 3-PGA.
