Question
Chapter 4, Problem 9SA
Summary Introduction
To review:
Why electrons that are excited by light energy during photosynthesis, sometimes move from one molecule to another, and do not move at other times.
Introduction:
Photosynthesis captures solar energy due to the ability of electrons to become excited by light and pas the energy on to the photosynthetic machinery in the chloroplast.

- Chloroplasts contain chlorophyll and carotenoids. Chlorophyll directly absorbs light for use in photosynthesis. Carotenoids absorb light and transfer the energy from light to chlorophyll. The efficiency of photosynthesis varies with the wavelengths of the light that illuminates the chloroplasts. In an experiment to study the relationship between the incoming light wavelengths and the chemical reactions of photosynthesis using a species of green algae, a researcher labeled the CO2 supply to the algae with 14C, and the H2O with 18O. Which of the following results is expected? More 14C is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red light. More 18O is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red light. More 14C is found in the algae when it is illuminated by blue-violet and red light than when it is illuminated by green light.

In the equation, the combining reactants and resulting products are expressed along with their respective numbers of molecules. Putting this in a simplified formula, the following equation represents this process.
