PHOTOSYNTHESIS

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!

nice.. i like the music too. what program was it made with?

Very helpful!!!

@SamuelHammer I wonder why the 5 -C in the lightindependent process can restart the cycle? I mean the light dependent part needed NADP, not 5 - C? I am talking about the stage when NADP collected the electrons and H+ to become NADPH+. Is the 5 - C the same as NADP or will it be converted in a reaction you don't mention?

One last question. Why do 2 of the 12 C:s in the 12 3CO2 go away and become sugar? What reaction is making these 2 C:s to be removed from the 12 3CO2.

Please do add video about the role played by CO2, N, P, K and micro nutrient in Photosynthesis.
