Carbon Fixation in Photosynthesis Rubisco Enzyme is key

‪@RubiscoSeeds‬ RuBisCo is an abbreviation of Ribulose-1,5-bisphosphate carboxylase oxygenase, the key universal plant enzyme responsible for removing atmospheric carbon dioxide and converting it into plant sugars, which drive metabolism, growth, and final yields of food, feed, and fiber in all plant species. This animation of the Calvin cycle is designed to show, in 3 stages, the major events in the synthesis of sugar in the stroma of chloroplasts: describes the three phases of the Calvin cycle: Carbon Fixation, Phosphoglycerate (PGA) Reduction, and the Regeneration of Ribulose bisphosphate (RuBP). For the sake of clarity, all of the enzymes, except Rubisco, have been omitted, and only the carbon skeletons of the intermediates are shown.
