Which of the following statements is not true of the light stage of photosynthesis?

The statement that is not true of the light stage of photosynthesis is that "Water is formed." During the light stage of photosynthesis, chlorophyll absorbs sunlight energy, which is then used to split water molecules into hydrogen ions, electrons, and oxygen gas. The oxygen gas is released into the atmosphere as a by-product, and the hydrogen ions and electrons are used to produce energy-rich molecules such as ATP and NADPH2, which are used in the next stage of photosynthesis. Therefore, water is not formed during the light stage of photosynthesis; instead, it is split into oxygen gas, hydrogen ions, and electrons.
