In the light reaction, when electrons are transferred from photosystem 1 to photosystem 2, it goes through an electron transport chain. This ETC pumps protons into the thykaloid. Those protons diffuse out of the thykaloid through ATP synthase which energizes a phosphate group to bond to ADP. This creates ATP.

Are ATP molecules made during the light-independent reactions of photosynthesis?
No, ATP molecules are not directly made during the light-independent reactions of photosynthesis (Calvin cycle). ATP is produced during the light-dependent reactions (Light reactions) of photosynthesis when light energy is used to convert ADP and inorganic phosphate into ATP. The ATP produced in the light reactions is then utilized as an energy source during the Calvin cycle to drive the conversion of carbon dioxide into glucose.
How is ATP made during the light reactions in photosynthesis?
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.
What is the role of ATP in light-dependent reaction?
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.
How are the dark reactions that occur in plants dependent on the light reactions?
The dark reactions that occur in plants are dependent on the light reactions because the dark reactions need ATP and NADPH. ATP and NADPH are energy molecules that dark reactions need to do their job.
Photosynthesis generates ATP and NADPH during what stages?
Photosynthesis generates ATP during the light-dependent reactions (photophosphorylation) and NADPH during the light-dependent reactions (photolysis of water and reduction of NADP+ to NADPH).
Are ATP molecules made during the light-independent reactions of photosynthesis?

What are the starting molecules for light independent reactions?
ATP and NADPH
What are the energy sources for the calvin cycle?
The energy sources for the Calvin cycle are ATP and NADPH, which are produced during the light-dependent reactions of photosynthesis. These molecules provide the necessary energy and reducing power for the conversion of carbon dioxide into carbohydrates in the Calvin cycle.
How much ATP is produced in the light dependent reactions?
In the light-dependent reactions of photosynthesis, ATP is produced through the process of photophosphorylation. Each cycle of the light-dependent reactions produces two molecules of ATP.
What is produced in light- dependent reactions?
In light dependent reactions ATP and NADPH are produced
What is made during the light dependent reaction and used during the light independent reactions of photosynthesis?

What are the energy carrying end products of the light harvesting reactions?
The energy-carrying end products of the light harvesting reactions are ATP and NADPH. These molecules serve as the main sources of chemical energy for the subsequent dark reactions of photosynthesis.
What is the high energy compound that is the result of light dependent reactions?
ATP is produced from the light reactions, which is then coupled with the light independent reactions. NADPH is also produced, but its job is to carry electrons which eventually make ATP.
