Photorespiration vs Respiration
(Similarities and Differences Photorespiration and Respiration)
Photorespiration is a type of respiration process occurs in plants in presence of light and at higher concentrations of oxygen. The photorespiration is also called C2 cycle or glycolate metabolism since the first stable product of the photorespiration reaction is a 2 carbon compound called glycolate. The respiration (also called normal respiration or dark respiration) is a metabolic pathway which releases energy-rich molecules by the breakdown of sugar molecules such as glucose. Even though the photorespiration and the normal respiration occur in the presence of oxygen, the two pathways are independent process and show considerable differences. The photorespiration is not universally present in all plants; rather it usually occurs in C3 plants. The process of photorespiration is essentially absent in C4 plants. The present post discusses the similarities and differences between photorespiration and normal respiration with a comparison table.
