Why does Photorespiration not occur in CAM Plants?

WebMar 18, 2024 · Rubisco aims to fix carbon dioxide, but can also fix oxygen molecules, which creates a toxic two-carbon compound. Rubisco fixes oxygen about 20 percent of the time, initiating a process called photorespiration that recycles the toxic compound. Photorespiration costs the plant energy it could have used to photosynthesize. WebThe CAM pathway is adapted to minimise water loss and photorespiration. Examples of CAM plants include cactus, pineapple, etc. CAM Photosynthesis CAM pathway is adapted in plants to perform photosynthesis under stress. The CAM pathway reduces photorespiration.
