How does light-dependent reactions make carbon for the light independent reactions ?

Question

$\textbf{Light dependent reaction:}$ Uses light energy to split a water molecule like thus:
$$2H_2O\longrightarrow 4H^++4e^-+O_2(\uparrow)$$
The hydrogens reduce the Nicotine Amide Adenine Diphosphate (NADP) to $[NADPH+H^+]$, that is an important reducing agent in the dark reaction. The energy required to create this NADPH is extracted slowly from the excited electrons by transporting them step by step to lower energy cytochrome molecules. Also, a couple of ATPs are produced and utilized.
(NB: there may also be other reducing agents like FAD, depending on the reaction center)

$\textbf{Dark Reaction:}$ This is where the carbon from $CO_2$ is fixed to glucose. For  this process, NADPH, FADH and other such reducing agents from the light reaction are required.
