kk so first u must understand tht the Light reaction and the calvin cycle r totally different

the light reaction aka the light dependent reaction depends on light, this reaction takes place in the stroma, in the chloroplast. U can research more about how it exactly works but basically the products of it is ATP and NADPH2. These products u get them after the light from the sun goes through cyclic or non cyclic reaction. ADP + Pi = ATP and NADPH+ + H+ = NADPH2

Then photosynthesis continues, the next step is carbon fixation. Carbon fixation is still part of the light dependent reaction. After the carbon gets fixed it enters the Calvin cycle.

the calvin cycle is now part of the dark reaction aka the light independent reactions, and like the name says it does not depend on light energy. The calvin cycle takes place in the thylakoid, which is in the chloroplast.

Here is goes through a series of steps in which enzymes to different stuff to it to get the CO2 into an organic molecule..The main enzyme is called Rubisco (which is a short form for Ribulose biphosphate carboxylase/oxygenase). the calvin cycle produces glucose, but u need 6 turns of the calvin cycle for every molecule of glucose. the calvin cycle also produces carbohydrates, like lipids.

Glucose is energy for the body, it can be broken down to get ATP, by a process called glycolysis

furthermore, there are other things tht happen in between these steps tht help photosynthesis continue, such as hydrolysis and chemiosmosis to produce more ATP through a concentration gradient and ATP synthataze. u must take into account tht these processes are very complex and the description above is only a brief overview, im not sure wut grade ur in n how much u need to kno. so with the names of it u can look it up

6CO2 + 6H2O -> C6H12O6 +6O2

carbon dioxide + water ( and photon energy ) = glucose + oxygen
