Cellular Respiration 1
Photosynthesis - Chapter 8
Topics you are responsible forThis chapter goes into much more detail than for what you will be responsible. Thus, the outline of these powerpoint slides and the question bank will be guides to what you should understand. You won’t be responsible for the details of bacterial photosynthesis, energy processing in reaction centers, the enhancement effect, or the specific steps of the electron transport. However, be sure to read about the properties of light and the absorption properties of different pigments.
