Understanding Photorespiration in Plants by ehani.randhawa is a document available to read on EtoBox.
Photorespiration is a light-dependent respiratory process in plants that occurs when CO2 levels drop, leading RuBisCO to bind O2 instead of CO2, resulting in the production of phosphoglycolate and a loss of CO2 fixation. This process reduces photosynthetic efficiency by up to 25% and is not essential for plant growth, yet it evolved due to the presence of oxygen in the atmosphere. C4 photosynthesis is an adaptation in some tropical plants that mitigates photorespiration by using PEP carboxylase to fix CO2,
