a. What is the molecular shape around the labeled carbon atom?
b. What is the hybridization around that same carbon?
c. Based on this structure, would you expect this molecule to absorb light in the
visible spectrum? Why or why not?

"Photosynthesis is a process in which light energy is captured and stored by an organism, and the stored energy is used to drive cellular processes," (Blankenship, p. 1). Photosynthesis doesn't just happen in green plants; it can occur in bacteria, as well. It occurs when light- harvesting molecules absorb energy in the form of light and transfer it to a reaction center, where light energy is converted to chemical energy. Most of us know about chlorophyll as the light-harvesting molecule, but there are many forms of chlorophyll found in different organisms. However, they all have similar properties when interacting with light.
