Form I Rubisco, found in green algae and vascular plants, is a hexadecamer composed of 8 large subunits (RbcL), encoded by the chloroplast genome and 8 small, nuclear-encoded subunits (RbcS). "Biology for NGSS has been specifically written to meet the high school life science requirements of the Next Generation Science Standards (NGSS)." The reaction catalysed by RuBisCO is as follows: The reaction involves enolisation of RuBP followed by carboxylation, which leads to the formation of an intermediate 3-keto-2-carboxyarabinitol-1,5-bisphosphate. The Calvin cycle is part of photosynthesis, which occurs in two stages. The active site for the substrate is present in the large chain. When molecular oxygen is the substrate, it converts RuBP to one molecule of phosphoglycerate and phosphoglycolate in the process called photorespiration. b. actin and myosin.
