adds CO2 to RuBP in the carbon fixation stage in photoresp.
Rubisco is an enzyme that is located in chloroplasts. It is responsible for fixing carbon dioxide during photosynthesis and oxygenating glucose during respiration.
catalyzing the first step in the Calvin Cycle: Carbon Fixation
the chloroplasts
Rubisco
When ther is a higher concentration of O2 than CO2, rubisco can bind O2 in place of CO2.
carbon fixation
Ribulose-1,5-bisphosphate carboxylase oxygenase
It occurs in the stroma.
Rubisco is an important enzyme
Rubisco
yes it is
Two substrates of rubisco when it acts as a carboxylase are that it catalyzes the first reaction and it catalyzes the oxidation of RuBP to phospho-glycolate.
Rubisco
When ther is a higher concentration of O2 than CO2, rubisco can bind O2 in place of CO2.
Enzymes usually end with the suffix "ase". Though this is a more modern method of naming enzymes, and rubisco has been identified for awhile now.
