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.
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.
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.
NADPH is used in the Calvin-Benson cycle to provide reducing power needed for the synthesis of carbohydrates. It helps to reduce 3-phosphoglycerate into glyceraldehyde-3-phosphate, a key intermediate in the cycle. This reduction reaction is catalyzed by the enzyme glyceraldehyde-3-phosphate dehydrogenase.
c) Uses ATP to add phosphorus group
NADPH donates high-energy electrons to the Calvin cycle, specifically to help reduce carbon dioxide into carbohydrates. These electrons come from the light-dependent reactions in photosynthesis and are crucial for the production of sugars in plants.
ATP adds chemical energy to the Calvin-Benson cycle.

During the light reactions of photosynthesis, ATP is made through a process called photophosphorylation. This process involves the conversion of light energy into chemical energy, which is used to add a phosphate group to ADP (adenosine diphosphate) to form ATP (adenosine triphosphate). This ATP is then used as an energy source for the Calvin cycle, the second stage of photosynthesis where glucose is produced.
ATP synthase
During the carbon reduction cycle in plants during phosphorylation, ATP is used to break down RuBP and form glucose and other sugars however ATP is Not used while the cycle is regenerating RuBP.
u add a hydrogen to a ADP and it makes ATP.

One molecule of ADP can be easily formed to make one form of ATP. All you need to do is add one phosphate group to the ADP and ATP is formed.ADP + P + energy --> ATPADP + P + energy --> ATP
