I keep getting “Light reactions” questions wrong in Photosynthesis in Higher Plants. What's the trap?
thinking the released oxygen comes from carbon dioxide.
The usual trap: thinking the released oxygen comes from carbon dioxide. How to avoid it: the O₂ you breathe from plants comes from splitting WATER (photolysis). Go back to the definition — occur in the thylakoid membranes, using light to make ATP and NADPH and releasing O₂ by splitting water.
