7999509316Photosynthesis6CO2 + 12H20 (light) - > C6H12O6 + 6O2 Process by which plants convert solar energy into energy stored in chemical bonds (light dependent and light independent reactions)0
7999509317Light dependent reactionsLight splits water to produce oxygen as waste. Energy from released electrons is used to form NADPH and ATP.1
7999509322Calvin CycleUses ATP and NADPH from light dependent reactions to fix carbon dioxide into G3P (sugar building block)2
7999509323PigmentsChemicals that absorb light energy to provide energy for photosynthesis Absorb colors that it does not reflect; reflects color that it shows (e.g., chlorophyll a, b, carotenoids)3

Need Notes?

While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
