ATP adds chemical energy to the Calvin-Benson cycle.
ATP is required in the Calvin-Benson cycle for the initial step of carbon fixation, where carbon dioxide is combined with ribulose-1,5-bisphosphate (RuBP) by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). This reaction produces an unstable intermediate compound that is quickly converted into two molecules of 3-phosphoglycerate.
The Calvin Benson cycle uses ATP (adenosine triphosphate), NADPH (Nicotinamide adenine dinucleotide phosphate), and CO2 (carbon dioxide) to create glucose.

NADPH serves as a reducing agent in the Calvin-Benson cycle, providing electrons to drive the conversion of 3-phosphoglycerate into glyceraldehyde-3-phosphate. This reduction step ultimately leads to the production of glucose during photosynthesis.
ATP adds chemical energy to the Calvin-Benson cycle.
In the Calvin-Benson cycle, ATP can donate a phosphate group to regenerate ribulose-1,5-bisphosphate (RuBP) in the regeneration phase of the cycle. This process is vital for the continuation of carbon fixation and the production of carbohydrates.

NADPH serves as a reducing agent in the Calvin-Benson cycle, providing electrons to drive the conversion of 3-phosphoglycerate into glyceraldehyde-3-phosphate. This reduction step ultimately leads to the production of glucose during photosynthesis.
In the second step of the Calvin-Benson cycle, the enzyme NADPH and ATP are needed to convert PGA (3-phosphoglycerate) into G3P (glyceraldehyde-3-phosphate).
ATP provides the necessary energy for the Calvin-Benson cycle, driving the conversion of carbon dioxide into glucose. During the cycle, ATP is used to phosphorylate intermediates, facilitating the reduction of 3-phosphoglycerate to glyceraldehyde-3-phosphate. This energy input is crucial for the synthesis of carbohydrates, making ATP a vital component of the process.
