Detailed explanation-1: -When the levels of carbon dioxide within a leaf are minimal, photorespiration occurs. This occurs when a plant is forced to close its stomata on hot, dry days to avoid excess water loss.
Detailed explanation-2: -In the photorespiration pathway, 6 O2 molecules combine with 6 RuBP acceptors, making 6 3-PGA molecules and 6 phosphoglycolate molecules. The 6 phosphoglycolate molecules enter a salvage pathway, which converts them into 3 3-PGA molecules and releases 3 carbons as CO2.
Detailed explanation-3: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Detailed explanation-4: -Photorespiration is the phenomenon of light-dependent release of CO2 due to oxygenase activity of RuBisCo.
