Question
Chapter 10.1, Problem 1CC
Summary Introduction
To describe: The diffusion of carbon dioxide (CO2) molecule used in the photosynthesis into the chloroplast of the leaf cells.
Concept introduction: Plasma membranes are selectively permeable. Non-polar compounds such as CO2, oxygen, and hydrocarbons can dissolve in the lipid bilayer and cross the plasma membrane without the help of plasma membrane proteins.

12. Why do the chlorophyll a molecules in photosystem II have an optimal absorbance of light at 680 nm, while the chlorophyll a molecules in photosystem I have an optimal absorbance of light at 700 nm? What does this tell you about the transfer of energy between these two photosystems during the light reactions?
