• Energy in photosynthesis Photosynthesis is the process by which plants effectively capture energy from the sun and store it for
later use by organisms. It's the fundamental process that enables the entire food chain. Actual
photosynthesis is a highly complex process involving many steps and many different chemicals. But the
idea of what is happening to the overall energy balance can be seen even in simpler reactions.
Let's consider a toy model that shows how an input of energy (for example from the sun) could be used
to combine water and carbon dioxide to create an organic molecule (formaldehyde) and oxygen and
effectively "store" that energy for use later. The figure below shows a the simplest possible such process.
The potential energy (binding deficit) of each bond is shown on the bonds. Pages Files options SideBar BERG Home

Instructor Reflections A. First check the stoichiometry. Are the number of each kind of atoms balanced? PERG Home
ChERG Home B. After you have balanced your equation, calculate the amount of bond energy deficit on each side of
the equation and identify which side needs to have energy added to it to make the equation balance
energetically and how much. What does it mean to say "you have to add energy to one side of the
equation to make the energy balance?" Recent Activity C. A particular direction of the reaction is labeled as exothermic. Is it correct? Explain how you know
using some schematic visual representation of the energies (potential energy graphs or energy bars). Spring 2017 Phys 132 Training Reminders
edited by Kim Moore D. Discuss where the energy is "stored". This is not a question with a clear answer, since the energy
relations in the reaction are a result of all the different bonds in all the different molecules. But discuss
the two questions, "When the reaction goes in the exothermic direction and energy becomes available Spring 2017 Physics 132 Reminder from…
edited by Kim Moore for use, where does the energy come from?" and "Where is it useful to think of the energy as being
stored and why?" If these two answers are different, reconcile why it is OK for them to be different. Spring 2017 Physics 132 Reminder from…
