Photorespiration, a process in plants where oxygen competes with carbon dioxide for the active site of the enzyme Rubisco, leading to a less efficient photosynthetic pathway. The process involves a complex interplay between chloroplasts, peroxisomes, and mitochondria to recycle carbon and nitrogen, while also dealing with toxic byproducts. Although photorespiration seems wasteful, it is vital for plants and may have protective roles. Scientists are exploring strategies to minimize photorespiration in crops to increase yields, such as introducing carbon-concentrating mechanisms or engineering alternative pathways, but these efforts are challenging due to the complex and ancient nature of this pathway
