Carbon-Fixing Reactions are also known as the Dark Reactions (or Light Independent Reactions). Calvin-Benson cycle: Also, known as the C3cycleas the 1ststable compound produced is a 3C compound Phosphoglyceric acid (PGA). The reactions that catalyze the reduction of CO2 to carbohydrates with the help of the ATP and NADPH2 generated by the light reactions are called the dark reaction. This step is also sometimes referred to as the 'Calvin-Benson Cycle,' as it gets its name from the scientists who discovered it. "@context": "http://schema.org", Light Reaction (also known as light dependent reaction) The light reaction uses chlorophyll (which is the main photosynthetic pigment) to capture light, and then uses the light energy to make ATP and NADPH. The light reaction process produces molecules that are required in the dark reaction stage. Notes on the C4 Cycle of Dark Reaction of Photosynthesis. This glucose molecule is the building block of creating everything else in the plant and what fuels every other organism that eats plants, like us. However, it is most active during the day when NADPH and ATP are abundant.

In dark reaction in photosynthesis, C3 pathway is noticed in green plants and C4 pathway is observed in desert plants. Photosynthesis is the process that transforms organisms from light energy into chemical energy. During the process, water is oxidized while carbon dioxide is reduced to produce carbohydrates. Calvin cycle is also known as the C3 cycle or light-independent or dark reaction of photosynthesis. Here, the carbon dioxide that we exhale as waste is used by plants performing photosynthesis. The key to creating sugars comes from carbon fixation, where inorganic carbon is fixed into organic carbon, such as sugars. In the dark reactions of photosynthesis, CO2 is added to a five-carbon sugar-phosphate known as A. cyclic AMP. It takes place in the stroma of the chlorophyll.

The dark reaction of photosynthesis takes place in the s troma of the chloroplasts as the enzymes of stroma do not require light but require ATP and NADPH 2 produced in the light reaction. The reverse reaction occurs, too, in glycolysis though in photosynthesis NADP is needed instead of the NAD consumed during glycolysis. The unstable 6C compound then breaks down into 2 3C compounds called glycerate-3-phosphate (GP). This equation for photosynthesis is a deceptively simple summary of a complex process.
