ATP is produced during the light-dependent reactions of photosynthesis through photophosphorylation. It provides energy for the Calvin cycle (dark reactions) by powering enzyme activity and providing the necessary energy for carbon fixation and the synthesis of carbohydrates.
Light supplies the energy to remove electrons from water and to transport those electrons to NADP+.

How does ATP couple exergonic and endergonic reactions?
ATP couples exergonic and endergonic reactions by acting as an energy carrier. In an exergonic reaction, ATP donates a phosphate group to fuel an endergonic reaction, thereby providing the necessary energy for the endergonic reaction to proceed. This transfer of a phosphate group releases energy and drives the endergonic reaction forward.
Name one reaction were ATP is required?
The first reaction of glycolysis, where glucose is phosphorylated (a phosphate group is added) to give glucose - 6 - phosphate requires ATP. This reaction is catalyzed by the enzyme hexokinase
How the products of the light reaction use in the dark reaction?
Those are NADPH and ATP. they are made out in the light reaction.
Why ATP is needed not GTP for hexokinase reaction?
ATP is used in the hexokinase reaction because it acts as the source of phosphate for the phosphorylation of glucose to form glucose-6-phosphate. Hexokinase specifically recognizes and phosphorylates glucose, and it has a higher affinity for ATP compared to GTP. Therefore, ATP is the preferred energy source for this reaction.
Is the formation of ATP an endergonic reaction?
No, the formation of ATP is an exergonic reaction, meaning it releases energy. This is because the conversion of ADP and inorganic phosphate to ATP is coupled with cellular processes that release energy, such as the breakdown of glucose during cellular respiration.
What is the role of ATP synthetase in the light dependent reaction?
In the presence of ATP synthetase enzyme ADP is converted in to ATP by uniting one more phosphate bond, storing chemical energy.
Where do the lightdependent reactions take place?
on the thykaloid membranes of the chloroplast.
What is the role of photosynthesis in the light reactions?
photosynthesis make food for life. ATP and NADPH2 will form in the light reaction.
What is produced by the reaction of the light dependent reaction?
ATP and NADHP
What is the role of ATP in an catalobic reaction?
ADP reduces when involved in a catabolic reaction and gains an extra phosphate group, becoming ATP (three phosphates), a molecule with more chemical energy stored than ADP (two phosphates).
Is ATP a reverse reaction?
No, ATP is a chemical (adenosine triphosphate).
What are the rate-limiting enzymes for ATP-PC system?
The rate-limiting enzyme for the ATP-PC system is creatine kinase, which catalyzes the transfer of a phosphate group from phosphocreatine to ADP to form ATP. This enzyme plays a crucial role in regulating the rate of ATP production during short bursts of high-intensity exercise.
What type of chemical reaction is ATP H2O - ADP Pi energy?
This reaction is a hydrolysis reaction, specifically the hydrolysis of ATP into ADP and inorganic phosphate (Pi). It releases energy stored in the high-energy bonds of ATP.
What molecule produced during the light reaction of photosynthesis are needed to Cary out the dark reaction?
ATP and NADH2
Do plant cells produce ATP during photosynthesis?
yesYes,ATP is produced in the light reaction. These are utilized in the dark reaction
What type of reaction is phosphoenolpyruvate ADP to Pyruvate ATP?
This reaction is a phosphorylation reaction where phosphoenolpyruvate transfers a phosphate group to ADP to form pyruvate and ATP. It is catalyzed by the enzyme pyruvate kinase, an important step in glycolysis for ATP production.
When ADP is created from ATP what type of reaction occurs?
A hydrolysis reaction occurs when ADP is created from ATP. In this reaction, a water molecule is used to break the bond between the phosphate group and ATP, resulting in the release of energy.
