Music by Ben Hammer. This animation is a very simplified description of the light-dependent reaction of photosynthesis, a unique biological process in which light energy (sunlight) is converted to chemical energy (adenosine triphosphate). The light-independent reaction takes place in all eukaryotic photoautotrophs (plants, algae, etc.). The process shown here occurs in less than a trillionth of a second, constantly (when light is available) and in great abundance (many many chloroplasts, many thylakoid membranes, and many chlorophyll molecules, etc.) in every photosynthetic cell. I was taught this process in graduate school at San Francisco State University and I have taught it in this simplified version for almost 15 years to my students at Boston University. After all this time, some of my students have begun to produce their own versions of this process, and I hope they will show up on YouTube soon!

  • hi, all the ATP ...

    hi, all the ATP produced in the light dependent reaction is used to fuel the enzymatic processes that run the "dark" reactions. actually the "dark" (i.e. light-independent) reactions take place at the same time as the light rxn is running. they occur in the stroma and continue running until about 20 minutes after sunset, when all the ATP from the light dependent reaction is used up.

  • The products of the ...

    The products of the light reactions, namely, ATP and NADPH, are used as the enrgy sources to power the Calvin Cycle (dark reactions).

    That was really helpful! But I have a question. How do dark reactions tie in?
