example of photosystem 2 where
the first part of the reaction leaves
oxygen as its by product.

12. Photosystem 2 uses carbon dioxide and water
from the environment to begin the process of
making energy. This is driven by the presence
of sunlight and chlorophyll. A continuation of
this lab is set for next week when we will look
closer at the steps involved in the second step
in photosynthesis.
