Question

Photosynthesis occurs in two phases-X and Y. X phase is also called light reaction. $Y$ phase is also called dark reaction. X phase produces reduced coenzyme NADPH and energy rich ATP molecules. Y phase catalyses assimilation of $\mathrm{CO}_{2}$ to carbohydrates.\ What does $X$ phase of photosynthesis involve?\

Professor PC Thomas Classes · Answer

(a) : The splitting of water takes place during light reaction $(\mathrm{X})$. It is associated with $\mathrm{PS} \|$ where water is split into $2 \mathrm{H}^{+}$, [0] and electrons. This creates oxygen, one of the net products of photosynthesis.
