Calvin Cycle: Definition, Function, Steps & Products

WebCarbon fixation is an important pathway for autotrophs living in various environments. Plants and cyanobacteria fix CO2 as organic compounds using solar energy mainly by the reductive pentose phosphate cycle (also called Calvin cycle, Calvin-Benson cycle, or Calvin-Benson-Bassham cycle) [MD:M00165].There are, at least, five additional carbon … WebCalvin cycle, also known as the light independent reaction, is the second stage of photosynthesis which is a very important stage. In this stage the carbon dioxide present in the atmosphere is taken in by the plant and is converted into carbon in the form of sugar, lipids and protein, in the form of glucose.
