Detailed explanation-1: -Rubisco can bind to either carbon dioxide or oxygen depending on environmental conditions. Binding to carbon dioxide and initiation of the Clavin cycle is favored at low temperatures and at a high carbon dioxide-to-oxygen ratio.

Detailed explanation-2: -Oxygen can bind to Rubisco instead of carbon dioxide, and through a process called photorespiration, oxygen reduces C3 plant photosynthetic efficiency and water use efficiency.

Detailed explanation-3: -RuBisCO’s primary function is photosynthesis and photorespiration. It catalyzes the first step in the C3 pathway or Calvin cycle, namely the carboxylation of RuBP. It leads to the production of two 3-PGA molecules. RuBisCO also has an affinity for oxygen, thus it binds to some O2 during the photorespiration process.

Detailed explanation-4: -RuBisCO is found in the mesophyll cell of
