# photosynthesis 2. Water is the source of hydrogenduring the light dependent reaction of photosynthesis. Water is split into hydrogen and oxygen. The oxygen is released into the atmosphere and the hydrogen is transferred to a carrier molecule called NADP, to produce NADPH. The NADPH is then used in the light independent reaction to reduce carbon dioxide to carbohydrate. See my answer to this question on WikiAnswers: What connects the light dependent reaction to the light independent reaction?
Mitochondria
Oxygen is released as a by product of photosynthesis.
This is called the light phase oh photosynthesis as opposed to the dark phase. During the light phase, photons excite enzymes on the thylakoid. Also can be known as Light-Dependent Reactions
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
