What is produced during the light reactions and is used during the Calvin cycle?
In photosynthesis, the the electron transport chain is part of the light dependent reactions. The "light independent reactions" are the Calvin-Benson cycle and do not include an electron transport chain, but the Calvin Cycle cannot proceed without the ATP and NADPH produced during the light reactions.
It cannot occur in the dark. It contains an enzyme called rubisco which is a light-activated enzyme. Also the Calvin cycle uses the chemical energy produced in the light reactions, and the light reactions need sunlight energy in order to produce the energy needed in the Calvin cycle. Hope that helps :)
The light dependent reactions create compounds which store the energy necessary for the Calvin Cycle to take place. This energy is stored in ATP (Adenosine Triphosphate), among other compounds, during the LDR. In the Calvin cycle, these are broken down, which releses energy. The energy released is used to create bonds between the parts of Glucose Another way to explain it in a simpler way is, when the light reaction has gone through once, it…
