Photorespiration. Photorespiration is a biochemical process in plants in which, especially under conditions of water stress, oxygen inhibits the Calvin cycle, the carbon fixation portion of photosynthesis.
Photorespiration is a problem for plants in hot, dry conditions. When it is hot and dry, plants close their stomata to conserve water. As a result, oxygen from the light-dependent reactions accumulates in leaf tissues.Oxygen competes with carbon dioxide for the binding site on rubisco.Photorespiration occurs when oxygen levels in the leaf are high relative to carbon dioxide levels.Some groups of plants have adapted to these conditions by using alternative pathways to fix carbon. C4and CAM plants avoid photorespiration in different ways. C4plants use spatial separation.hotorespiration occurs when oxygen levels in the leaf are high relative to carbon dioxide levels.
