Biology: The Light Dependent Reaction
In the Light Dependent phase of photosynthesis, light strikes Photosystem II, causing the electron to become excited. The excited electron bounces up to an electron acceptor, and is then passed down the electron transport chain. As the electron goes down the ETC, the electron
loses energy. The energy released is used to produce ATP. At the same time, light is hitting Photosystem I, which makes it's electron's excited. The electrons are passed to another electron …showed first 75 words of 181 total…

…showed last 75 words of 181 total…photolysis). Oxygen is released to the atmosphere. At the end of the second ETC, the electron is picked up by NADP+. The hydrogen + ions that resulted from photolysis are also picked up by the NADP+, making NADPH.
The light dependent reaction takes place in the thylakoid membrane.
