Which of the following reactions produces the oxygen released by photosynthesis? A)reduction of NADP⁺ B)splitting of water molecules C)chemiosmosis D)electron transfer in photosystem I.

Question

Quizplus · Accepted Answer

The oxygen released during photosynthesis comes from the splitting of water molecules, a process known as photolysis. This occurs in the thylakoid membrane of the chloroplast, specifically in photosystem II, as light energy is used to break apart water molecules into oxygen, electrons, and protons. The electrons are then used in the electron transport chain to generate ATP and NADPH, which are used in the carbon fixation reactions.
