Answer the following questions using the virtual lab light phase video. Where do the electrons for the light reaction come from? How does light cause protons to be pumped? If photosystem 1 (the second photosystem in the chain) is mutated and does not work, will the plant still be able to provide ATP for the Dark reaction? PL Q Search

Question
**The Light Phase of Photosynthesis at the Molecular Level**

*Watch the video*  
An embedded video illustrates the molecular mechanisms of the light phase of photosynthesis, focusing on Photosystem II. The video provides a detailed visual representation of the processes involved.

**Exploration and Questions**

After watching the virtual lab light phase video, consider the following questions:

1. **Where do the electrons for the light reaction come from?**

2. **How does light cause protons to be pumped?**

3. **If Photosystem I (the second photosystem in the chain) is mutated and does not work, will the plant still be able to provide ATP for the Dark reaction?**

These questions guide you in understanding the mechanisms by which light energy is transformed into chemical energy during photosynthesis.
