photosynthesis; plant Background In C3 photosynthesis, the C3 cycle occurs mainly in mesophyll cells, where carbon dioxide is fixed by Rubisco and then enters into the Calvin cycle. Subsequently, carbohydrates are pro-duced by going through a series of enzymatic chemical reactions.1 In contrast to C3 photosynthesis, C4 photosynthesis

Three types of photosynthesis occur in the plant world, commonly re ferred to as the C3, C4, and cam pathways. The first to be described was C3 photosynthesis, discovered in experiments with algae, spinach, and barley (Calvin and Benson 1948).

Photosynthesis is the biochemical process by which every plant fixes carbon dioxide to form carbohydrates, and although the fundamental steps remain the same across all plants, slight tweaks have occurred throughout the history of the lineage to produce two main pathways, known as C 3 and C 4 photosynthesis.
