The route of electron flow during the light reactions of photosynthesis that involves both photosystems (I and II) and produces ATP, NADPH, and O₂ is called linear electron flow.

Here are the steps:

1. Light energy is absorbed by the chlorophyll in Photosystem II, exciting the electrons to a higher energy level.

2. These high-energy electrons are captured by the primary electron acceptor and passed along a series of molecules in an electron transport chain.

3. As the electrons move along the chain, their energy is used to pump hydrogen ions across the thylakoid membrane, creating a concentration gradient.

4. The electrons eventually reach Photosystem I, where they are re-energized by light energy.

5. The re-energized electrons are captured by another primary electron acceptor and passed along a second electron transport chain.
