Jack Frain Wanninger Biology Honors 23 October 2016 Harnessing the Power of Photosynthesis While it is highly effective, photosynthesis is not an entirely perfect system. The process uses two reactions: light reactions, which absorb energy from the sun, and dark reactions, which uses this energy to make simple sugars. However, the light reactions are much more operative and efficient than the dark reaction, so much of the light energy is being wasted in between the reactions. In this article, called “Tapping the Unused Potential of Photosynthesis (with a Heterologous Electron Sink)” Researchers at the University of Southamptom engineered an enzyme between the reactions so more light is used. The electrons are instead sent to degrade the pollutant atrazine, a banned herbicide. Amazingly, the enzyme was produced in a lab, not taken from another organism. This article has everything to do with our current unit. The topic of our unit was photosynthesis and cellular respiration, and we learned all about the two processes.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
