What does “Light reactions” actually mean in Photosynthesis in Higher Plants, and why does it matter for NEET?
occur in the thylakoid membranes, using light to make ATP and NADPH and releasing O₂ by splitting water.
In simple words: occur in the thylakoid membranes, using light to make ATP and NADPH and releasing O₂ by splitting water. Getting Light reactions clear matters because NEET questions on Photosynthesis in Higher Plants usually test this idea directly, not just a formula you memorised.
Key point
Light reactions
Common mistake
thinking the released oxygen comes from carbon dioxide.
Memory tip
the O₂ you breathe from plants comes from splitting WATER (photolysis).
