Detailed explanation-1: -Photorespiration begins in the chloroplast, when rubisco attaches O 2 to RuBP in its oxygenase reaction. Two molecules are produced: a three-carbon compound, 3-PGA, and a two-carbon compound, phosphoglycolate.

Detailed explanation-2: -In the photorespiration pathway, RuBP binds to O2 to create one molecule of PGA (3C chemical) and phosphoglycolate (2C compound). There is no sugar synthesis or ATP synthesis. Rather, it results in the emission of CO2 as a result of the use of ATP. It results in a 25% reduction in stationary CO2 emissions.

Detailed explanation-3: -The 3-phosphoglycerate produced during photorespiration, like that produced during photosynthesis, is converted to triose phosphate and used to regenerate RuBP.

Detailed explanation-4: -During photorespiration, RuBP binds with O2 to form No worries!

Detailed explanation-5: -Photorespiration (also known as the oxidative photosynthetic carbon cycle or C2 cycle) refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis.
