Photorespiration is a process in plant which is otherwise called as photosynthetic oxidation cycle. It attempts to reduce the consequences of a wasteful oxygenation reaction by the enzyme RuBisCO. The ratio between 3-carbon intermediates (serine and glycerate) and 2-carbon (glycine) having NH\\\\(_{2}\\\\) group formed in photosynthetic oxidation cycle is 2:1.
