This video-based song describes the light-dependent reactions and processes of photosynthesis in a fun and memorable way. Students will learn how a plant uses energy from the sun, water, chlorophyll, and enzymes to produce ATP and NADPH, the energy-rich compounds that power the Calvin cycle, part 2 of photosynthesis. Be sure to check out the corresponding BioL-O-Gee R.A.P. "Photosynthesis Light Reactions" animated music video on our Biology Music Videos YouTube channel!
