Carbon dioxide is easily excluded in proteins that bind oxygen, such as myoglobin, due to its slight size difference. However, in rubisco, an oxygen molecule can easily bind in the location intended to bind to carbon dioxide. The oxygen is then added by Rubisco to the sugar chain, creating an improperly oxygenated product.
<h3>What is Photorespiration ?</h3>
The oxidative photosynthetic carbon cycle, also known as the C2 cycle or photorespiration, is a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis.
RuBisCO aids in the Calvin-Benson cycle's CO2 fixation (carboxylation), but it also fixes O2. The latter reaction is where photorespiration begins.
